Additional functions
MEDIBUS/MEDIBUS.X Protocol
MEDIBUS and MEDIBUS.X are software protocols for
use in transferring data between Apollo and an
external medical or non-medical device (e.g.
hemodynamic monitors, data management systems, or
a Windows-based computer) via the RS-232 interface
see:
– 9037426, 6th edition or higher
or
– 9052608, third edition or higher.

WARNING!
Risk of patient injury
Data transferred via MEDIBUS/MEDIBUS.X
interfaces are for information only and are not
intended as a basis for diagnosis or therapy
decisions. The data accessible via this interface
are not intended for a decentralized alarm system
in accordance with IEC60601-1-8:2012 (in the
sense of remote monitoring).

WARNING!
Risk of electric shock
Connecting devices to the auxiliary outlets of the
anesthesia machine can cause an increase in
leakage current beyond permissible values if the
protective conductor of a device fails.
Part Number: 9053586, 3rd edition

Check the leakage current when connecting

devices to the auxiliary outlets. If connecting a
device (or devices) increases the leakage current
to a value which exceeds the permissible value,
do not use the auxiliary outlets of the anesthesia
machine: use a separate wall socket.
The system must fulfill the requirements for
medical electrical equipment in accordance with
the relevant standards, see page 308.

 System Components

Vaporizers (Optional)
Note: Before operating the vaporizer, pay special
attention to the Instructions for Use of the
vaporizer being used. Note especially the
vaporizer flow limits.
The Dräger Vapor anesthetic agent vaporizers are
used to enrich the fresh gas with a precisely metered
quantity of vapor from the liquid anesthetic agent
being used, i.e. Isoflurane, Halothane, Enflurane,
Sevoflurane, or Desflurane.
When using a Desflurane vaporizer, it must be
connected to mains power. The auxiliary power outlet
(IEC/EN 60320-2-2/F) near the vaporizer exclusion
system is provided for that purpose.
The vaporizers being used must comply with
standard ISO 8835-4. If the internal gas
measurement system fails, an independent
measurement system complying with ISO 21647
must be used

WARNING!
Risk of patient injury
Risk of ambient air contamination
To prevent vaporizer leakage, which may lead to
low fresh-gas delivery, impaired manual
ventilation, or contamination of the ambient air,
the D-Vapor must be mounted very carefully.
Avoid catching the D-Vapor power cable behind/
underneath the housing. Make sure that the
D-Vapor is upright. Always perform a leak test
Part Number: 9053586, 3rd edition

after mounting the vaporizer.

CAUTION!
Risk of patient injury
If the vaporizer is not correctly mounted, the fresh-
gas flow will not be supplied with anesthetic agent
and the patient will not receive the correct
anesthesia.
Always double-check the position of the vaporizer,
make sure it is correctly mounted and do not mount
the vaporizer park holder close to the operable
vaporizer.

Instructions for Use Apollo SW 4.5n 33

System Components

CAUTION!
Risk of ambient environment contamination and
patient injury
The parked vaporizer may be mistakenly opened if
the park holder is positioned right next to the
vaporizer mount on the anesthesia machine.
To avoid contaminating the ambient environment
and endangering the patient, always doublecheck
to make sure the correct vaporizer is being opened
before doing so.

Vaporizer exclusion systems

The exclusion systems available for the Apollo are
described below.

Dräger Vapor Interlock 2 System Figure 2. Dräger Vapor Interlock 2 System

(Optional)
The Dräger Interlock 2 system is used to ensure that
only one of two vaporizers can be used at a time. It
OP00520
has a selector lever used to select which vaporizer is
enabled.
Moving the selector lever away from the desired
vaporizer allows that vaporizer to be used and the
other to be locked out of use.
1
Note that the selector lever (1 in Figure 2) is shown in
the center position. This ensures that both vaporizers

Part Number: 9053586, 3rd edition

are in the locked position. Also, this is the
recommended position for the selector lever when
moving the Apollo.

Selectatec (Optional)
The interlock system for the Selectatec is built into
the vaporizers. When a vaporizer is selected for use,
the interlocking index pins will protrude from the
sides of the vaporizer thereby not allowing the
adjacent vaporizer to be opened. For more specific
information on the Selectatec, refer to the Selectatec
Vaporizer’s instruction manual.

 System Components

Dräger Auto Exclusion 2-Vaporizer

Mount (Optional)
This system has an automatic interlock system that
ensures only one vaporizer can be used at a time.
When one of the two vaporizers is selected for use
(opened), the interlock mechanism within that
vaporizer’s mounting system is activated
automatically, preventing the other vaporizer from
being used.

Note: Only vaporizers labeled as “AUTO Table 1. Dräger Auto Exclusion Vaporizer Technical Data
EXCLUSION” vaporizers are compatible with Normal ≤ 10 L/min Dräger Vapor 2000
the Dräger Auto Exclusion 2-Vaporizer Operating Instruction for Use
Mount. See Table 1 for the Auto Exclusion Range Manual’s delivered
Vaporizer technical data. concentration accuracy
values apply.
When using a Desflurane vaporizer, it must be
plugged into the auxiliary power outlet located on the Extended >10 ≤ 15 L/min Dräger auto exclusion
side of the machine above the vaporizer mount. Operating vaporizer concentration
Range output accuracy may be
reduced.

Dräger Auto Exclusion 3-Vaporizer Figure 3. Dräger Auto Exclusion 3-Vaporizer Mount
Mount (Optional)
This system has an automatic interlock system that
ensures only one vaporizer can be used at a time.
When any one of the three vaporizers is selected for
use (opened), the interlock mechanism within that
Part Number: 9053586, 3rd edition

vaporizer’s mounting system is activated

automatically, preventing the other two vaporizers
from being used.
1
Note: Only vaporizers labeled as “AUTO
EXCLUSION” vaporizers are compatible with
the Dräger Auto Exclusion 3-Vaporizer
Mount. See Table 1 for the Auto Exclusion
Vaporizer technical data.
When using a Desflurane vaporizer, it must be
plugged into the auxiliary power outlet located on the
side of the machine above the vaporizer mount.
Note: The Desflurane vaporizer should be installed
in the far left position (1 in Figure 3) with the
Dräger Auto Exclusion 3-Vaporizer Mount in
order to have optimum viewing area of the
display screen.

System Components

APL valve
The APL valve has two functions. It limits the
maximum pressure during manual ventilation and
exhausts excess gas into the scavenger system
during manual and spontaneous ventilation.
The APL valve is connected to the patient airway
through the ventilator. It functions only when the
ventilator is in Manual/Spontaneous mode.
The adjustment knob (1 in Figure 4) is used to select
between spontaneous and manual modes of
ventilation. It’s labeled to indicated approximate
pressure settings.
For spontaneous ventilation: Figure 4. APL Valve
Pressure is released for spontaneous ventilation
when the adjustment knob is rotated fully
counterclockwise, when the index mark on the knob
lines up with the index mark on the bottom of the APL
valve (2 in Figure 4). Spontaneous ventilation 1
eliminates both resistance to patient exhalation and
the need to readjust back pressure.
For manual ventilation:
In manual mode, the APL valve adjustment knob can
be rotated to change the approximate pressure at
which gas will flow through the valve and into the
scavenging system. Clockwise rotation of the
adjustment knob increases the pressure, and 2
counterclockwise rotation of the adjustment knob
decreases the pressure. Pulling up on the APL valve
head will temporarily relieve pressure.
Note: The APL valve is automatically excluded

Part Number: 9053586, 3rd edition

from the breathing circuit whenever an
automatic ventilation mode is selected. It is
suggested that even in automatic ventilation,
the APL valve is adjusted to a pressure that
is safe for the patient.

WARNING!
Risk of patient injury
If the APL valve becomes blocked due to e.g.,
lines or cables being caught under the valve
head, the patient may be endangered.
Route all cables away from the APL valve; do
not hang lines, hoses or cables, e.g. the sample
line, on or near the APL valve.

 System Components

O2 flush Figure 5. Location of O2 Flush

A manually operated O2 flush valve is located on the
front of the machine (1 in Figure 5). When actuated,
the valve delivers an unmetered flow of at least
35 L/min to the breathing system and breathing bag
while bypassing the ventilator. The Apollo does not
have to be switched on to use the O2 flush. 1
1. To operate the O2 flush, press the O2+ button.
Oxygen flows into the breathing system without
anesthetic gas as long as the button is pressed
in.

Auxiliary oxygen flow meter

The auxiliary oxygen flow meter delivers a metered Figure 6. Auxiliary Oxygen flow meter
flow of pure oxygen, used, for example in the delivery
of oxygen through a nasal cannula. Auxiliary oxygen
can be used in any ventilation mode, in Standby, or
O2

even if the machine is switched off. 10

CAUTION! 6

Risk of inadequate pressure monitoring 4

The optional auxiliary outlets are not pressure 2

monitored.
Pressure monitoring must be ensured by the 1
connected device.

WARNING!
Part Number: 9053586, 3rd edition

Risk of fire
Cauterizing close to a source of oxygen can
lead to fire. Make sure that all connectors (e.g.,
Y-piece, breathing hoses including the
breathing bag, breathing system, external fresh-
gas outlet, oxygen therapy, anesthetic gas
receiving system) are leak-free so that oxygen
leakage cannot endanger the user or the patient.

Instructions for Use Apollo SW 4.5n 37

System Components

WARNING!
Risk of patient injury
If the patient is connected to the auxiliary
oxygen outlet without a means of pressure
relief, high pressure will be applied and the
patient endangered.
Do not connect the patient directly to the
auxiliary oxygen outlet without ensuring a
means of pressure relief.

When finishing oxygen therapy, make sure the flow

tube is completely closed:
1. Turn the flow knob (1 in Figure 6) clockwise until
it is completely closed to cut off the oxygen flow.

humidity falls below a minimum set point, the
following undesirable reactions can occur,
independent of the type of lime and the
inhalation anesthetic being used:
– reduced CO2 absorption;
– increased heat build-up in the absorber and
thus, an increased breathing gas
temperature;
– formation of CO;
– absorption and/or decomposition of the
inhalation anesthetic.
These reactions could pose a danger to the
patient.
If using dry gases, only briefly flush the
anesthesia system and only if necessary.

Connecting the backup gas cylinders

Figure 23. Cylinder Yoke Locations

CAUTION!
Risk of gas supply failure
Should the pipeline gas supply fail, the backup gas
cylinders on the anesthesia machine will provide a
reserve gas supply.
To prevent a complete gas failure, the backup gas
cylinders should remain on the device, valves
closed, in reserve even if the anesthesia machine is
connected to pipeline gas supply.

The Apollo is equipped with ANSI standard pin-

indexed hanger yokes for E-size cylinders to connect
backup gas cylinders to the anesthesia machine. The
yoke for O2 is standard, the yokes for N2O and Air
are optional. All cylinder yokes are located on the
back of the machine as shown in Figure 23.

WARNING!
Risk of gas supply failure
When attaching a cylinder, ensure that only one
washer is installed between the cylinder and the
yoke gas inlet. The use of multiple washers will
inhibit the pin-index safety system. Be sure to
verify the presence of the index pins each time a
cylinder is installed. Never attempt to override
the pin-index safety system.

WARNING!

Part Number: 9053586, 3rd edition

Risk of supply failure
If pressure reducers not having the required
sensors and measurement features are used
instead of Dräger pressure reducers, backup
gas cylinders and their fill levels will not be
subject to alarm and monitoring functionalities
during the power-on self test and operation.
Without this monitoring, in the event of a loss of
the pipeline gas supply, the backup functionality
of the backup gas cylinders may not be
available. If monitoring for the remaining
capacity of the backup gas cylinders is not
available, the user must take other equivalent
measures.

blocked HME filter or filter in this position at the

Y-piece, the measurement system would produce
negative pressure situations in the patient’s lungs.

Observing the resistance and compliance

WARNING!
Risk due to additional components in breathing
circuit
When additional components are used or in the
case of hose configurations that differ from the
standard or recommended hose configurations,
the inspiratory and expiratory breathing
resistances may exceed the standard
requirements.
If such configurations are used, the user must
pay particular attention to the measured values.
Observe the instructions for use of the
additional components.

WARNING!
Risk of increased rebreathing
If coaxial hoses are used, leakages between the
inner and outer hose cannot be detected during
the leak test.
To avoid insufficient gas exchange and
rebreathing of CO2, monitor the measured gas
concentration extremely carefully.
Part Number: 9053586, 3rd edition

WARNING!
Risk due to incorrect measured values
Replacing the breathing hoses, filters,
vaporizers, or soda lime may change the
calculated leakage and compliance values of
the anesthesia machine and affect the therapy.
– Perform a leakage and compliance test after
replacing breathing hoses, particularly
extendable hoses, vaporizers, and soda
lime.
– Perform a leakage and compliance test after
adjusting the length of extendable hoses.

Instructions for Use Apollo SW 4.5n 81

System Setup

WARNING!
Risk when adjusting the hose length
When the hose length is changed, resistance
and compliance may change. This can result in
an increased or reduced ventilation volume for
neonates.
Do not use extendable hoses, particularly for
neonates.

During spontaneous breathing, higher resistance

values mean that the patient must do more breathing
work.
In volume-controlled ventilation, an increased
resistance has a slight effect on the applied volume
during the inspiration. However, the peak pressure
increases at a constant plateau pressure. For this
reason, the time constant increases during the
expiratory phase. If the expiration times are too short,
the lungs might not be emptied completely, resulting
in a dynamic overfilling of the lungs (air trapping).
In pressure-controlled ventilation, an increased
resistance can reduce the inspiratory or expiratory
volume.
Before the self test is performed, all accessories1) to
be used must be connected. The extendable hoses
must be drawn out to the length required by the user.
This is the only way of ensuring that the compliance
of the breathing system and breathing hoses is
determined correctly and a corrected tidal volume is

Part Number: 9053586, 3rd edition

automatically applied during volume-controlled
ventilation.

1) If necessary, take into consideration additional parts such

as water traps or additional hoses.

82 Instructions for Use Apollo SW 4.5n

 System Setup

Calculating the resistance of the breathing sys-

tem and connected accessories
To keep the patients' work of breathing as low as
possible, according to ISO 8835-2 and
ISO 80601-2-13 a total inspiratory and expiratory
resistance of 6.0 hPa (cmH2O) at 60 L/min may not
be exceeded.
The "Specifications" chapter states the inspiratory
and expiratory breathing resistance of the breathing
system, not including the breathing hoses. This
allows for the calculation of the resistance of the
breathing circuit using different hose sets and/or
filters.
The following formula are used to calculate the
resistance (R):
RInspiration =
RBreathingsystem_insp + RInspHose + RBagHose +
RInsp-Filter(port) + RInspFilter(Y-piece)
RExpiration =
RBreathingsystem_exp + RExpHose + RExpFilter(port) +
RExpFilter(Y-piece)
When calculating the resistance, only accessory
resistance values and peak flows must be used that
are applicable for the respective accessory category
and patient category, e.g., resistance value for adults
(60 L/min), for children (30 L/min), or for neonates
(5 L/min).

 System Setup

WARNING!
Risk of electric shock
Connecting devices to the auxiliary outlets of
the anesthesia machine can cause an increase
in leakage current beyond permissible values if
the protective conductor of a device fails.
Check the leakage current when connecting
devices to the auxiliary outlets. If connecting a
device or several devices increases the leakage
current to a value which exceeds the
permissible value, do not use the auxiliary
outlets of the anesthesia machine. Instead, use
a mains power socket on the wall.
The system must fulfill the requirements for

WARNING!
Risk of patient injury
The soda lime loses humidity. Generally, if the
humidity falls below a minimum set point, the
following undesirable reactions can occur,
independent of the type of lime and the
inhalation anesthetic being used:
– reduced CO2 absorption,
– increased heat build-up in the absorber and
thus an increased breathing gas
temperature,
– formation of CO,
– absorption and/or decomposition of the
anesthetic agent.
These reactions could pose a danger to the
patient.
If using dry gases, only flush the anesthesia
system briefly, and only if necessary.

WARNING!
Risk of patient injury
If the flow controls are left open, the ensuing
flow of gas may dry out the soda lime,
endangering the patient.
The flow control valves should be closed when
the machine is in the standby mode or when it is
switched off.

Note the Instructions for Use of the Drägersorb 800 +

Verify that the scavenging system is ready for
use:
1. Check that the scavenger hose between the
AGS and the scavenger connection on back of
the machine is securely connected.
2. Check that the hose between the output
connector on the scavenger and the hospital
waste-gas disposal system is securely
connected.
3. Make sure that the AGSS is ready for operation.
Check if the flow indicator at the AGS floats
between the two marks.

WARNING!
Risk of device failure and/or patient injury
Canceling the self test may lead to
malfunctions. Special attention is required
during operation.
Always perform a complete self test, unless
acting in an emergency situation. If canceled for
an emergency situation, perform a complete
self test as soon as practicable.

System compliance
Apollo determines the current compliance of the
breathing circuit consisting of filters, hoses, and a
Y-piece. Typical values for the inspiratory system
compliance are between 0.5 and 2.6 mL/hPa
(mL/cmH2O).
In volume-controlled ventilation, system compliance
is compensated. For this purpose, Apollo increases
the applied tidal volume on the basis of the difference
between PEEP and plateau pressure in accordance
with the determined compliance value.

Leak tests
The Apollo tests for leaks in the mechanical
subsystem and in the Man/Spont system.
Part Number: 9053586, 3rd edition

Setting the fresh-gas flow

Figure 53. Flow Control Knobs
1. Set the fresh-gas flow to desired levels using the
flow control knobs on the front panel of the
machine (1 in Figure 53).

CAUTION!
Risk of patient injury
The use of minimum flow or low flow settings may
lead to the accumulation of metabolic products in
the breathing system.
To avoid this risk, use appropriate soda lime, or set
higher fresh-gas flows, and always use the gas
measurement module provided by the anesthesia
machine. Vol. AF

SORC (Sensitive Oxygen Ratio Controller)

The Apollo is equipped with an O2 minimum delivery
system to avoid hypoxic gas mixtures when N2O is
selected as the carrier gas.
At flow rates of 200 mL/min and above, the N2O
concentration can be freely set between 0 and 79%.
During an O2 shortage, the SORC limits the N2O
concentration in the fresh gas, so that the O2
Part Number: 9053586, 3rd edition

concentration does not fall below 21%. When the

N2O flow control is open and the O2 flow control is
closed (or O2 flow is less than 200 mL/min), the
SORC prevents N2O flow. During N2O failure, O2 can
still be administered.
The SORC is not active when Air is selected as the
carrier gas and 100% Air can be metered throughout
the entire flow range.

Fresh-gas Failure Detection

During operation, the Apollo checks that the piston
cylinder unit has a sufficient level of fresh gas.
If a sufficient level of fresh gas is not possible, the
system first displays the message "FGAS LOW OR
LEAK".

Instructions for Use Apollo SW 4.5n 113

Operation Summary

In addition the alarm “PINSP. NOT ACHIEVED” or “VT

NOT ACHIEVED” is displayed if the system is unable
to maintain the defined ventilation.
To ensure continued ventilation, the anesthesia
machine will use ambient air to supplement the gas
volume if it is too low. This may change the gas
composition. Carefully check the gas composition.

WARNING!
Risk of patient awareness
If a complete gas supply failure occurs, the
anesthesia machine will continue to function
with ambient air. However, anesthestic agents
will no longer be delivered and the inspiratory
gas composition will be diluted.
Carefully monitor the gas mixture and, if
necessary, use IV anesthetics.

DrägerService can change the behavior of the device

so that it does not use ambient air for supplementing
the gas volume. The device will then ventilate with
limited VT or PINSP. if possible.
1. Increase the fresh-gas flow.
2. Seal any possible leaks.

Operation Summary

Changing soda lime

In Standby Conf., see “Configuring the default
settings in Standby” on page 201 , the maximum
number of use days can be set for the absorber
based on clinical hygiene guidelines. Use days
monitoring is then available on the Check List, during
the Self Test and on the Self Test Results page (“Self
test results” on page 102).
A reusable absorber or the disposable CLIC
absorber can be used with the Apollo. The soda lime
must be exchanged, if:
– the soda lime in the absorber has turned violet.
The color indicator can regenerate slowly and
the soda lime may revert to white, but its
absorption capacity is nevertheless spent. You
should therefore dispose of used absorbers
immediately.
– the fractional inspiratory CO2 concentration
FiCO2 exceeds 5 mmHg.
Information on when the soda lime has been
changed will be logged in the system when the

Changing between ventilation

modes
When changing to a different ventilation mode, the
presettings are adopted or appropriately derived from
the parameters of the preceding mode.
Parameters which are identical in both ventilation
modes are adopted directly (e.g. Freq., TINSP, ΔPPS,
Trigger).
When changing from volume-controlled to
pressure-controlled ventilation modes:
The measured parameter PLAT is adopted as the
new value for PINSP. If a valid plateau pressure value
is not available, the last value used in the case will be
used as the preset value (the preset value of PINSP
will be at least PEEP + 5). The PAW LOW alarm limit
will be pre-set to PINSP-2 if the alarm limit was higher
than PINSP-2 during volume-controlled ventilation.
When changing from pressure-controlled to
volume-controlled ventilation modes:
The new tidal volume VT is adopted from the
measured minute volume MV and the set frequency
Freq. Only the minute volume applied by the
ventilator is taken into account. Pressure supported
breathing strokes by the patient are disregarded.
When changing from automatic ventilation
modes to Pressure Support mode (optional):
The set PEEP, ΔPPS, and Trigger are adopted.
If ΔPPS and/or Trigger were set to “OFF”, the last
values used are adopted in Pressure Support mode.
In all other cases the configured default settings are

used.
The PAW LOW alarm limit will be pre-set to
PEEP+ΔPPS-2 if the alarm limit was higher than
PEEP+ΔPPS-2 during automatic ventilation mode.
When changing from Pressure Support mode
(optional) to automatic ventilation modes:
The set PEEP, ΔPPS, and Trigger values are
adopted. The last values that were set are used for
the other parameters and the configured default
settings in all other cases.
Note: In minimum flow mode, the following
secondary effects may occur that affect
ventilation of the patient:
– Leakage: Check if the breathing bag is
adequately filled.

146 Instructions for Use Apollo SW 4.5n

 Ventilation

– Increased condensation: possible

impairment of the flow measurement and
increased water collection in the upper
diaphragm of the ventilator. Check the
upper diaphragm on a daily basis and
empty if necessary.
– Difference between O2 setting and
inspiratory O2 concentration: The O2
consumption of the patient causes a
difference between the set parameter and
measured value.

Changing from manual ventilation Man.Spont. to

automatic ventilation modes:
The ventilation parameters correspond to the last
values set. When the ventilation mode (e.g., Volume
Mode) is used for the first time, the configured default
settings can be adopted. This also applies when the
patient is ventilated in an automatic ventilation mode
(e.g., Pressure Mode) before switching to manual

Certain alarms are disabled automatically in order to

avoid artifacts. See the chapter “Alarms” for complete
information.
Excess fresh gas can be discharged into the
anesthetic gas scavenging line via the breathing
system of the Apollo. For this purpose, the non-
rebreathing system must be connected to the
Y-piece of the breathing hoses connected to the
breathing system.

WARNING!
Risk of patient injury
If the bag does not inflate, the patient will not
receive adequate ventilation. Switch to the
Apollo internal breathing system and ventilate
the patient using an automatic ventilation mode.

Overview
The Apollo has three basic screens for the display of
monitoring information: standard, data, and trend.
The gas measurement and gas delivery windows
remain displayed in all three screens, but the
information presented in the graphical/numerical
window will change, depending on the selected
screen and user configuration.
This chapter defines all monitoring parameters and
provides instructions for selecting and configuring
monitoring screens and parameters.

WARNING!
Risk of patient injury
If the display loses patient data, it is possible
that active monitoring is not being performed.
Close patient observation or alternate
monitoring de-vices should be used until
monitor function is restored.

minute volume

WARNING!
Risk of insufficient ventilation
The displayed spontaneous minute volume
(MVSPON) indicates the volumes of the patient's
breathing and the mechanical breathing
support. If the mechanical breathing support is
triggered by small tidal volumes of the patient, a
major portion of the spontaneous minute
volume is not achieved by the patient's
breathing but the mechanical breathing
support. In this case, MVSPON indicates a high
value although the actual spontaneous minute
volume is very low.
Do not make therapy decisions based solely on
the displayed value of MVSPON.

The low flow wizard

Part Number: 9053586, 3rd edition

WARNING!
Risk of patient injury
If used incorrectly, the reaction time of fresh-
gas concentration changes could increase,
increasing also the risk of undesirable soda
lime compounds.
This tool should not be used when higher flows
are required such as during induction,
emergence, or other times when rapid changes
to the concentration of gases in the circuit are
desired, or when the chemical pharmacology of
the agent being used indicates otherwise.

The low flow wizard shows bar graphs for the

minimum required flow (leak and uptake) and for the
total fresh-gas flow. Both graphs have the same
scale.

Instructions for Use Apollo SW 4.5n 161

Monitoring

The total fresh-gas flow bar graph has three ranges:

Bar graph
Indication Meaning
color

too much yellow fresh-gas delivery is more

than 1 L/min above the
gas consumption
(leak + uptake)
efficient green fresh-gas delivery efficient
too little red fresh-gas delivery less
than minimum flow
required (leak + uptake)

Gas consumption depends on patient uptake,

leakage, and the CO2 volume converted in the
absorber.
If fresh-gas data is unavailable, the bar graph will be
inactive and the text will appear grayed out.
Volumeter Module
The volumeter module shows the tidal volume VT
and minute volume as bar graphs. The scales can be
configured by the user (see the chapter

Part Number: 9053586, 3rd edition

“Configuration” for more information).
The Tidal Volume (Upper) Graph
The tidal volume graph increases during the
inspiratory flow and decreases during the expiratory
flow. A blue vertical line remains on the graph to
indicate the inspiratory volume, while the bar recedes
from the line to indicate the expiratory phase.
The expiratory tidal volume is shown in numerics
above the graph. Leakage is indicated by the bar
remaining in the graph at the end of the expiratory
phase.

 Monitoring

Inspiratory phase Expiratory phase End of expiratory phase

The Minute Volume (Lower) Graph

The minute volume, or volumeter, provides a
graphical and numerical indication of the expiratory
minute volume. Each unit in the graph represents
one breath. The total volume is shown above the
graph and the expired time is shown beside the
graph in seconds. The measured values are
displayed for four minutes and the deleted.
To start the volumeter
1. Press the rotary knob.
The measurement begins and stops automatically
after 60 seconds. The volumeter is stopped if the
rotary knob is pressed again within 60 seconds; the
values are deleted and the rotary knob must be
pressed again to restart.

Gas measurement
The concentration of O2, CO2, and of the anesthetic
agents N2O, halothane, enflurane, isoflurane,
desflurane, and sevoflurane is measured.
Part Number: 9053586, 3rd edition

Apollo automatically identifies the anesthetic agent

used and adjusts the measurement and monitoring
of the anesthetic gas concentration to suit the gas
identified.
When no anesthetic agent is applied, the message
“No agent” appears below the O2/N2O
measurement.

Instructions for Use Apollo SW 4.5n 163

Monitoring

WARNING!
Risk of gas measurement failure
The presence of aerosols in the breathing
circuit should be avoided, as the displayed
agent concentrations and/or the water trap
membrane may be affected.
The presence of organic cleaning agents or
gases containing haloalkanes (e.g. CFC) will
impair the accuracy of the integrated gas
analyzer.

Calibration
The patient-gas measuring module is automatically Figure 86. Example of Calibration Messages
calibrated every time the device is started and then 1 2 3
regularly with ambient air, as long as the device is
switched on (see “Zeroing interval” on page 298).
During calibration, messages informing the user
about the calibration appear on the screen
(1 and 2 in Figure 86), and the measurement values
are replaced with the word CAL (3 in Figure 86).

CO2 and O2
The CO2 and O2 concentrations are side-stream
measured, thus delaying an indication of the real-
time values by approximately four seconds. The
displayed CO2 and O2 curves are not synchronized
with the pressure and flow curves.
If apnea occurs, the display for etCO2 is replaced by
the message apnea CO2. The apnea time [min:sec]

Part Number: 9053586, 3rd edition

is displayed instead of the measured value.

164 Instructions for Use Apollo SW 4.5n

 Monitoring

Anesthetic agents
The anesthetic agents are side-stream measured in
the same way as CO2 and O2.

Mixture detection
Apollo automatically detects the anesthetic gas used
and switches the measurement and monitoring of
anesthetic gas concentration to the gas detected.
If there is a mixture of two volatile anesthetic agents,
the concentration of the secondary anesthetic agent
is displayed if the xMAC value is 0.1 MAC or greater.
The gas with the higher expiratory xMAC value is
displayed above the secondary anesthetic agent.
A secondary anesthetic agent becomes the main
anesthetic agent if its xMAC value exceeds the MAC
value of the main anesthetic agent by 0.2 MAC.
A mixture of more than two volatile anesthetic agents
cannot be reliably detected. In this case, the
anesthetic gas values are no longer displayed and an
alarm is generated.
Note: A mixture of more than two agents may lead
to a temporary time-out of the measured O2
value.

WARNING!
Risk of patient injury
If the anesthetic agent displayed does not
match the label of the anesthetic vaporizer
being applied (open), make sure the vaporizer is
filled correctly.
Part Number: 9053586, 3rd edition

Monitoring

MAC definition
1 MAC is the anesthetic gas concentration in the
blood at 760 mmHg (1013 hPa), at which 50% of
patients no longer respond to a skin incision with
movement.
The integrated MAC algorithm is based on the MAC
values as indicated on the list. These values are
merely guideline values. It is the information on the
slip accompanying the anesthetic agents which is
binding.

1 MAC corresponds to:

(in 100 % O2)
Halothane 0.77 Vol.%
Enflurane 1.7 Vol.%
Isoflurane 1.15 Vol.%
Desflurane 6.0 Vol.%
Sevoflurane 2.1 Vol.%
N 2O 105 Vol.%

The MAC values are dependent on the age of the

patient. The values indicated in the table relate to an
age of 40 years.

Age-dependent MAC values

The MAC values used in Apollo are corrected for Figure 87. Influence of Age on MAC
age. Therefore make sure that the age of the patient
is entered correctly. Calculation follows the equation Influence of age on the MAC value
from W.W. Mapleson (British Journal of Anaesthesia
1996, P. 179-185). The equation applies to patients
older than 1 year of age.

Part Number: 9053586, 3rd edition

MACage-corrected = MAC 40 x 10 (-0.00269 x (age - 40))
The formula shows the reciprocal relationship Desflurane
existing between MAC and age.
Apollo automatically adjusts the MAC calculation 0.2*N2O

according to the ambient pressure.

Note: The age “1” is used when the age is set to
“<1”. Special attention is required for patients Sevoflurane
younger than one year. Enflurane

xMAC display (MAC multiple)

The MAC value is a simple navigation aid for
anesthetic gas metering.
Apollo indicates the MAC multiple (xMAC), which is
determined from the present expiratory
measurements and the age-dependent MAC values.
In the gas of gas mixtures, the respective multiples
for nitrous oxide and the anesthetic agents are added
in accordance with the following equation:

exp. conc. agent1 exp. conc. agent2 exp. conc. N2O

xMAC= + +
MACage-corrected agent1 MACage-corrected agent2 MACage-corrected N2O
Example:
Exp. Sev. = 1.5 Vol.%
Exp. N2O = 60 Vol.%
Age = 10 years
MACage-corrected of Sev.: MAC = 2.2 Vol.%
MACage-corrected of N2O: MAC = 125 Vol.%
xMAC = 0.7 + 0.5 = 1.2

The influence of other medication (opiates or intrave-

nous hypnotics) is not taken into account when cal-
culating MAC values.

Automatic agent alarm activation

The lower alarm limit of an anesthetic agent is Figure 88. Automatic alarm limit
intended to help the user prevent patient awareness xMAC insp. xMAC
during a case. Examples of problems which, if
ignored or unnoticed, could lead to patient exp. xMAC
awareness include leaks in the breathing circuit, an

incorrect fitted vaporizer, or an insufficient anesthetic

gas supply to a vaporizer. 1.0
The alarm limits for the anesthetic agents have to be
activated manually and are often not used for that lower alarm limit
reason. Apollo provides an alarm management
0.3
system for the xMAC level, which is automatically
activated when the expiratory xMAC reaches about
0.3. 1 2 3 t

After activation (1 in Figure 88), the automatic alarm

limit adapts to the level of anesthesia supplied. It
adapts only to increasing xMAC values. Apollo
generates an advisory message ‘MAC low’ as soon
as the expiratory xMAC value falls below the alarm
limit (2 in Figure 88).

Without confirmation the priority will automatically

change to a caution after 30 sec. When the alarm
message is present the alarm limit menu will

Never use two adhesive strips as this can lead to
venous pulsation, causing the pulse signal to fail.

CAUTION!
Risk of inaccurate data
In the presence of shock, low blood pressure,
severe vasoconstriction, major anemia,
hypothermia, arterial occlusion proximal to
thesensor, and asystolia, the pulse signal may fail.

Note: The displayed plethysmogram is a relative

indicator of the pulse amplitude. Its scale is
not absolute and it should only be used to

Figure 110. Applying the SpO2 Sensor
Reusable sensor for short-term monitoring of
relatively quiet patients weighing over 88 lbs (40 kg).
The sensor is ideally positioned on the index finger,
although any of the other fingers may also be used, if
required. The little finger should be used if the patient
is particularly large or obese.
1. Open the clip slightly and slide the sensor onto
the finger. The tip of the finger must touch the
end of the sensor and the soft padding should
rest on the nail and tip of the finger. The lead
should be on top of the finger.
2. Make sure that the finger is not compressed or
hurt by the clip.

Alarm priorities and alarm signals

Figure 111. Alarm Display
Rather than being displayed immediately, some
alarms are shown with a delay after a limit violation. 1 2
In addition, combinations with other alarms, and the
length of time for which the alarm is issued, may 3
cause the priority of an alarm to change, similarly the 4
acknowledgement of a technical alarm.
Alarm messages are color-coded and assigned to
three priority classes by the Apollo, depending on
their urgency:

Warning
– Message with highest priority.
– A warning message requires immediate action.
– Text flashes on red background.
– Red LED (2 in Figure 111) flashes, accompanied
by a repetitive tone sequence.

Caution
– Message with medium priority.
– A caution message requires immediate action.
– Text flashes on yellow background.
– Yellow LED (3 in Figure 111) flashes,
accompanied by a repetitive 3-tone sequence.

Advisory/technical message
– Message with lowest priority.
Part Number: 9053586, 3rd edition

– Text displayed on cyan background.

Advisory
– Yellow LED (3 in Figure 111) illuminates
continuously, accompanied by a single 2-tone
sequence.

Instructions for Use Apollo SW 4.5n 185

Alarms

Technical message
– Yellow LED (3 in Figure 111) illuminates
continuously without any acoustic tone.
– These messages must be noted and action
taken if necessary.
Dräger recommends the user to remain close to the
anesthesia machine, i.e. within a range of up to
12 feet (4 meters), to allow for quick recognition and
action in the event of an alarm.
Whenever an alarm message is displayed, the alarm
LED flashes or lights up continuously and an
acoustic tone sequence indicates the alarm priority
class.
In addition, a flashing help text is displayed in the
prompt field.
In the case of limit-based alarms, the corresponding
measured values will be highlighted by a colored
background (1 in Figure 111) and will flash.
The color of the background reflects the color-coding
of the alarm priority (red, yellow, cyan).
For a complete list of Apollo alarm messages, see
“Alarm - Cause - Remedy” on page 267.

Downgrading alarm priorities

Selected technical alarms can be downgraded to a
lower priority, or deleted completely once
acknowledged.

1. Press the > < key on the side of the monitor

screen (4 in Figure 111).

Part Number: 9053586, 3rd edition

Setting the alarm volume
The alarm volume can be set by the user in the
standby configuration screen. See page 202 for
complete instructions.
The alarm volume can also be set during operation
(see page 221).

Alarms in Standby mode

Machine-related alarms, e.g. failure of equipment
components and a number of special operating
states, are indicated to the user in Standby mode. A
message is displayed in the alarm message field in
the status field, but no acoustic tone is annunciated.

186 Instructions for Use Apollo SW 4.5n

 Alarms

Alarm displays
Alarm messages are displayed in the alarm message Figure 112. Multiple Alarms Display
field (1 in Figure 112) in order of priority. 1 2
All displayed alarms are sorted according to the three
classes defined on page 185. Within these classes,
the alarms are sorted and displayed according to an
internal priority system. A priority of 31 indicates the 3
highest, a priority of 1 the lowest priority. The priority
numbers are given in the table in the chapter “Alarm -
Cause - Remedy” on page 267. The internal priorities
are not displayed.
Up to three messages can be displayed
simultaneously. In some cases, the corresponding
measured values are highlighted on the screen by a
flashing background in addition to the alarm
message.

If more than three alarms occur simultaneously, the Figure 113. Additional Alarm Fields
more
symbol > < appears to the right of the alarm
message field (2 in Figure 112), and the button
>Show All Alarms< is activated on the right side of
the screen (3 in Figure 112).
When this button is pressed, the upper curve display
is replaced by up to six additional alarm message
fields for 15 seconds (see Figure 113).
If more than nine alarm messages are
simultaneously active, the lowest priority alarms will
not be displayed until the total number of active
alarm messages falls below nine.
Part Number: 9053586, 3rd edition

The alarm tone sequence accompanying a displayed

alarm message with the highest priority will always
be sounded at least once completely. The alarm tone
sequences of alarm messages with lower priorities
will not sound if a higher priority alarm is activated,
i.e. the tone sequence thereof will sound.
If an alarm message of the same class as an active
alarm message is generated, the alarm tone of the
new alarm only sounds if the priority is higher than
the priority of the previously active alarm.
The upper curve display reappears when the button
>Show All Alarms< is pressed again or when the
15 seconds have expired.

CAUTION!
Risk of inadequate monitoring
National standards require a minimum monitoring
with some alarm functions. These standards may
not be met if the alarm function of the SpO2
monitoring parameter is disabled.
Only disable this monitoring parameter after
consulting national standards.
Audio and visual alarms can be disabled by adjusting
the default alarm limits in the standby configuration
screen. Certain alarms can also be disabled
automatically, based on ventilation mode. See the
chapter “Configuration” for complete information.

 Alarms

During operation certain alarms can be disabled

globally (see “Enabling/disabling alarms globally
during operation” on page 191) or individually in the
alarm limits menu (see “Displaying and setting alarm
limits” on page 195).
If all the alarms connected to a measurement
function have been disabled, the measured value will
be marked with the symbol > < (1 in Figure 115).
If only certain alarm limits have been disabled for a
monitoring parameter, one symbol > > < or > < <
appears next to the parameter (2 in Figure 115).
If the upper and lower alarm limits of a monitoring
parameter have been disabled, but the respective
apnea monitoring feature is still active, the symbol
> _ < appears next to the parameter.
If an apnea monitoring feature derived from a specific
monitoring parameter has been disabled, that
parameter will be marked with the symbol > <.
A monitoring parameter is always marked with the
symbol > < if, after switching from Standby into a
ventilation mode, a valid CO2 breathing phase has
not yet been detected for the parameters O2, N2O,
MV, or inspiratory and expiratory CO2, or respectively
a valid pulse signal for SpO2. As soon as a breathing
phase has been detected or valid pulse signals are
available for SpO2, the symbol disappears.

Alarm behaviour when changing ventila-

tion modes
The Apollo has an automatic suppression of active
MV low and apnea alarms implemented, when
Part Number: 9053586, 3rd edition

changing ventilation modes.

This suppression applies when the user changes
from a ventilation mode with a low mandatory
ventilation support, such as ManSpont, to a
ventilation mode with a higher mandatory ventilation,
such as Volume Mode. After this timeout the alarms
will only be generated again if the preconditions are
valid.
If the ’MV low’ alarm is active during such a change,
the alarm is suppressed for 45 sec (no alarm display
and no audible tone). The apnea alarms can be
suppressed for a certain time, depending on the
ventilation settings in the new ventilation mode.
If the settings for freq/FreqMIN are < 6 bpm the
apnea alarms will be suppressed for 30 sec,
otherwise the timeout is 15 sec.

Instructions for Use Apollo SW 4.5n 189

Alarms

Limit-based alarms activated in respective ventilation modes

When a ventilation mode is changed, the Apollo sets
the alarms ON or OFF as indicated in the table
below. Some alarms can be then be enabled or
disabled manually by the user.

WARNING!
Risk of patient injury
As anesthesia machines within one care area
might have different alarm limit configurations,
make sure that the preset alarm limits are
appropriate for the new patient. Also make sure
that the alarm system has not been rendered
useless by setting the alarm limits to extreme
values or by their alarm tone being disabled.

Alarms

The displayed value may differ marginally due to

rounding errors, since Apollo calculates the values
internally with much greater accuracy.
The new alarm limits for PAW are calculated by the
Apollo on the basis of the mean values for PEAK,
PLAT, and PEEP over the last four machine strokes.
Spontaneous breaths by the patient and triggered
Pressure Support strokes are not taken into account.
If the mean of the last (up to four) measured breaths
cannot be calculated, the measured value of the last
breath is used instead.

Volume Mode, Volume AF,

Pressure Mode,
Pressure Support
PAW PEAK + 5 cmH2O or
high alarm limit PLAT + 10 cmH2O,
[cmH2O] whichever is greater
PAW 0.6 x (PLAT – PEEP)
low alarm limit + PEEP – 1,
[cmH2O] but at least 3

To restore individual alarm limits for MV and PAW:

 Configuration

Overview
The user can configure settings on the Apollo in
Standby mode as well as during operation. Standby
configuration allows the user to save a complete set
of defaults that are invoked automatically when the
machine is switched on (see “Configuring the default
settings in Standby” below). The configuration
settings that can be made during operation are more
limited and are valid only until the machine is
switched off (see “Configuration during operation” on
page 220).

Configuring the default settings in

Standby
Default settings describe settings which the Figure 123. Location of Standby Config Key
anesthesia machine starts with when it is switched
on.
The default settings for ventilation, fresh-gas
delivery, and monitoring can be activated while in
Standby by pressing the >Restore Default
Settings< button (1 in Figure 123) on the standby
screen.
The default settings can be configured in Standby as
follows: 2

1. Press the standby key > <, and confirm by

pushing the rotary knob.
2. Press the >Default Config< button
(2 in Figure 123). 1

Figure 124. Password Screen

The user is requested to enter a four-digit
password in order to prevent unauthorized
changes to the basic functions (see Figure 124).
The four-digit password is assigned at the
factory.
If desired, the function can be disabled by
DrägerService or a new password set.
3. Select and confirm the figures successively from
the line displayed using the rotary knob. The
password is represented by asterisks (****)
below the line of numbers
The menu Standby Conf. for selecting the default
values is displayed when the password has been
entered correctly, see Figure 125.

Alarm volume
See 1 in Figure 125.
The minimum alarm volume can be set to a value
between 1 to 9. The standard alarm volume cannot
be set below this limit.

 Configuration

Alarm volume Factory setting

Minimum: 1 to 9 4
Default: 1 to 9 5
The default volume cannot be set lower than the
minimum volume.

WARNING!
Risk of use error
If using features like the ’breathing sound’ or
when operating under loud ambient conditions,
the auditory alarm signals may not be heard.
Always set the alarm tone to a sufficiently loud
volume.

The NO O2 SUPPLY alarm is always announced at

the maximum volume.
Apollo takes into account the national regulations of
certain countries which require a minimum volume of
45 dB (A). For these countries Apollo is shipped with
factory settings in which the alarm volume cannot be
set to values between 1 to 3.
However, the minimum alarm volume can be set to
values between 1 to 3 by service personnel, if
required.

Breathing sound

to
9 = maximum volume
Factory setting: 0
The breathing sound is produced by the Breathing
Sound Emulator (BSE) module. This module
converts the measured inspiratory and expiratory
flow values into audible sounds similar to a breathing
sound.
The volume depends on the set patient age. This
dependency allows optimal volume at all flow levels.
All alarms are still audible with the breathing sound
volume set to the maximum.

WARNING!
Risk of use error
If using features like the ’breathing sound’ or
when operating under loud ambient conditions,
the auditory alarm signals may not be heard.
Always set the alarm tone to a sufficiently loud
volume.

The NO O2 SUPPLY alarm is always announced at

the maximum volume.
Apollo takes into account the national regulations of
certain countries which require a minimum volume of
45 dB (A). Settings 1 to 3 are not available for these
countries. The minimum volume can be adjusted in
the default settings.

Breathing sound

to
9 = maximum volume
The breathing sound is produced by the Breathing
Sound Emulator (BSE) module. This module
converts the measured inspiratory and expiratory
flow values into audible sounds similar to a breathing
sound.
The sound volume depends on the set patient age.
This dependency allows optimal volume at all flow
levels.
All alarms are still audible with the breathing sound
volume set to the maximum.

Cleaning and Disinfection

Guidelines
Applies to inhalation anesthetic machines after use
with all patients. Governmental regulations must be
observed in those cases where patients have
notifiable diseases.
Material properties have been taken into account in
the specified cleaning/disinfection instructions.
Correct functioning of the anesthesia machine is not
impaired by the recommended measures. They can
be incorporated into the hospital's own hygiene
schedules.
Follow the institution’s policies regarding specific
methods and agents for cleaning and sterilization,
subject to the criteria listed below. Determination of
the need and frequency of sterilization of any
particular component is the responsibility of the
institution.
Sterilization procedures should be performed
according to procedures established by the
institution, following the specific instructions provided
by the manufacturer of the sterilizing equipment or
agent to be used. Such policies, procedures, and
Part Number: 9053586, 3rd edition

instructions should ultimately be consistent with

established principles of clinical microbiology and
infection control.

Proper Cleaning/Disinfection
Sequence
If equipment parts are to be cleaned by hand, they
must always be disinfected first for personal
protection.
When equipment parts are to be cleaned and
disinfected by machine, they should always be
cleaned first and then disinfected.

Instructions for Use Apollo SW 4.5n 235

Cleaning and Maintenance

Cleaning/Disinfection Objective
and Methods
The purpose of the described cleaning/disinfection
measures is to provide each patient with a reliably
disinfected anesthetic machine, i.e. a machine free
from all unhealthy micro-organisms. Sterility is
required only for the intubation tube and bronchial
aspiration catheter.
The following disinfection methods may be used:
– Disinfection by wiping the surface of the device
(see “Choice of disinfectant” on page 237)
– Mechanical cleaning with high-temperature
disinfection (≥199 °F (93 °C) , ≥10 min). This is
the preferred method for many Apollo
components; a suitable cleaning agent must be
added.
– Manual disinfection in a bath. Extensive personal
protection is required due to inhalation of vapors.
Equipment parts should be cleaned and disinfected
by machine for hygienic conditioning purposes
(EN ISO 15883, in preparation).
Complex, thermally stable functional components,
such as the breathing system, can be easily cleaned
and disinfected by machine, but are not always dried
sufficiently. Subsequent vacuum disinfection in hot
steam or steam sterilization is recommended to dry
off the remaining water.
– Vacuum disinfection in hot steam at 167 °F
(75 °C) for 20 minutes or 221 °F (105 °C) for
1 minute, for example.
– Steam sterilization, for example at 250 °F

Part Number: 9053586, 3rd edition

(121 °C) for max. 20 minutes or 273 °F (134 °C)
for max. 8 minutes. Higher temperatures may
impair the service life of the functional
components.
High-temperature disinfection does not have any
cleaning effect. Such methods should therefore only
be used on functional components which have
already been cleaned by hand or by machine.
Machines, associated components, and equipment
parts must be inspected visually and packaged for
storage or transport. Simple packaging with
corresponding labeling is sufficient for this purpose.
This is not necessary if the components and
equipment parts are not to be stored and/or
transported.

236 Instructions for Use Apollo SW 4.5n

 Cleaning and Maintenance

Disinfecting/Cleaning/Sterilizing
Choice of disinfectant
Only products suitable for surface disinfection may
be used for disinfection. Testing was performed with
Incidin Extra N and Incidur (wiping), and Gigasept FF
and Korsolex Extra (disinfection by immersion).

The following products are not suitable and should

not be used:
– Compounds containing phenols
– Halogen-releasing compounds
– Strong organic acids
– Oxygen-releasing compounds
In addition to the main agents, disinfectants
frequently also contain additives which may damage
the materials used. The supplier/manufacturer of the
cleaning agent/disinfectant should be contacted if
there is any doubt as to the suitability of a product.

Surfaces
Surfaces of the Apollo, compressed gas hoses, and
cables:

– Wipe off impurities with a damp disposable cloth.

– Disinfect with a wipe disinfectant. (Note the
manufacturer's Instructions for Use.)

WARNING!
Risk of electric shock
Part Number: 9053586, 3rd edition

Fluids entering the device can damage it

causing malfunctions and endangering the
patient. Wipe the device with only moist, not
dripping wet, objects, e.g. sponges or rags. Do
not place canisters with liquids on or over the
device.

Risk of patient injury
The soda lime loses humidity. Generally, if the
humidity falls below a minimum set point, the
following undesirable reactions can occur,
independent of the type of lime and the
inhalation anesthetic being used:
– reduced CO2 absorption;
– increased heat build-up in the absorber and
thus, an increased breathing gas
temperature;
– formation of CO;
– absorption and/or decomposition of the
inhalation anesthetic.

 Troubleshooting

Overview
This chapter discusses several types of failure that
may occur on the Apollo and provides courses of
action following the failure. An alphabetical list of all
Apollo alarms and their causes and remedies is
provided on page 267.
Note: If the remedies suggested in this chapter do
not resolve a fault that may impair the proper
functioning of the Apollo, use another device.

Power failure Figure 174. Power Fail Alarm Message

In the event of power failure the Apollo automatically 1 2
switches to the built-in uninterruptible power supply
UPS (battery backup). In this case, the auxiliary
outlets will not be supplied with power.
Provided that the battery is fully charged, operation
can be continued with the current settings for at least
30 minutes (up to 90 minutes, depending on the
ventilation parameters).
The message POWER FAIL is displayed in the
status field on the screen (1 in Figure 174), together
with the remaining battery capacity in percent
(2 in Figure 174).
If the battery is almost empty, the message
BATTERY LOW is displayed.
Apollo permits manual ventilation with 100% O2 in
the event of a power failure and empty batteries. The
fresh-gas measurements, ventilator, and monitoring
are inactive.
Part Number: 9053586, 3rd edition

If all electrical power fails, all individual settings,

including alarm limits which are not saved in the
default settings, will be lost.
If the power supply is recovered, the anesthesia
machine behaves as described in “Ventilator failure”
on page 262 and “Fresh-gas delivery failure” on
page 263; see also the alarm message
GAS + VENT. FAIL on page 271. To continue
operation for emergency situations, switch the
anesthesia machine off and then on again and refer
to page 107 of these instructions for use.
In case of power failure:
1. Close N2O and Air flow valves.
2. Check vaporizer setting.
3. Set O2 flow to the desired level using the total
flow meter.

Instructions for Use Apollo SW 4.5n 259

Troubleshooting

4. Ventilate the patient manually.

5. Ensure adequate substitute monitoring.

WARNING!
Risk of patient injury
If all power supplies fail, the screen display will
be dark and automatic ventilation will cease.
The patient must be ventilated manually.

Note: If a D-Vapor is in use and a power failure

occurs, refer to the Instructions for Use of the
D-Vapor for a description of system behavior
in a power fail situation.
Note: Refer to the total flow meter for approximate
flow (see the chapter “Specifications” of the
instructions for use for accuracy).

Gas failure
If the gas supply fails, the Apollo displays a Figure 175. NO O2 SUPPLY Alarm Message
corresponding message in the status field at the top 1
of the screen (1 in Figure 175):
NO AIR SUPPLY, NO N2O SUPPLY, or
NO O2 SUPPLY
1. Open the valve on the corresponding backup
cylinder at the back of the machine
(see Figure 176).
2. Restore the pipeline supply.

Part Number: 9053586, 3rd edition

If there is no cylinder backup supply for the failed
gas, the corresponding LED on the front panel of the
machine will flash red.
In case of N2O or air failure, 100% O2 should be
delivered; be sure to set the O2 to an appropriate
flow.

CAUTION!
Risk of patient injury
In case of a gas supply failure, adjust the gas
concentration manually.
Note the contra-indications for 100 % O2.

260 Instructions for Use Apollo SW 4.5n

 Troubleshooting

In case of O2 failure, the SORC prevents hypoxic gas

mixtures. Oxygen must be restored immediately.
Figure 176. Cylinder Locations
If the pipeline gas supply for O2 and Air fails, and
there is no cylinder backup supply for the failed gas,
operation of the ventilator is still possible in automatic
ventilation modes as the electrically driven piston
ventilator does not need drive gas for operation.
Disconnecting the breathing bag from the breathing
bag arm enables the entrainment of ambient air, thus
substituting the failed fresh gas.
1. Disconnect breathing bag from breathing bag
arm.
2. Continue ventilation using an automatic
ventilation mode.

WARNING!
Risk of patient awareness
If a complete gas supply failure occurs, further
operation may continue by supplying the
anesthesia machine with ambient air.
Anesthetic agents will no longer be delivered
and the inspiratory gas composition will be
diluted thereby raising the issue of patient
awareness.
Therefore carefully monitor the gas mixture
and, if necessary, use IV anesthetics.

WARNING!
Risk of gas supply contamination
When the central gas supply is connected, the
Part Number: 9053586, 3rd edition

smallest internal leakage can cause

contamination of the supply gases.
Disconnect the compressed gas hoses from the
terminal unit if the central gas supply fails
during operation.

The failure of the pipeline gas supply may lead to the

failure of connected devices.

CAUTION!
Risk of increased ambient gas concentrations
If the breathing bag is not attached, expiratory
anesthetic agents can escape from the breathing
system.
Make sure the breathing bag is attached and
ensure sufficient ambient air circulation.

Instructions for Use Apollo SW 4.5n 261

Troubleshooting

The cylinder valve of the corresponding backup gas

cylinder must be closed again after restoring the
pipeline gas supply.

WARNING!
Risk of gas supply failure
If the valves remain open when connected to
the pipeline gas supply, gas may be withdrawn
from the backup gas cylinders.
Close cylinder valves whenever the pipeline gas
supply is sufficient.

Ventilator failure
If the ventilator fails, the following message is Figure 177. Ventilator Failure Messages
displayed in the status field on the screen 3 1
(1 in Figure 177):
VENTILATOR FAIL
The ventilation buttons are removed from the screen
and a prompt appears advising the user how to

Gas measurement

Sidestream gas measurement

The gas sampled via the water trap is returned to the breathing system and included in measurement and delivery
calculations. The inlet of the gas measurement system contains a filter in the water trap and there is a filter in the outlet of the
sample gas return. All values are measured under ATPS conditions. The sample flow is standardized to STPD conditions.
The measurement is corrected for ambient pressure.
Due to the T10...90 time and the sampling rate, the accuracies of the measured values for O2, N2O, and anesthetic agent may
deviate at respiratory rates of 75 bpm and an I:E ratio of 1:2. The influence of respiratory rate and I:E ratio on accuracy has
been verified in a simulated breathing system using a rectangular waveform for the gas concentration.
Endtidal measured values are calculated for each breath from the local maxima and minima of the realtime measurements
during expiration. If CO2 respiratory phases are detected, the sample flow is compensated during ventilation and flow
measurement.
