INTRODUCTION
The ResMed S8 ELITE™ system is designed to provide continuous positive airway
pressure (CPAP) therapy to patients with obstructive sleep apnea (OSA). The device
delivers a fixed treatment pressure within the range 4 to 20 cm H2O.
Patients with OSA experience recurrent obstruction of their upper airway (apneas)
due to relaxation of the tongue and soft palate while they sleep. Common symptoms
are associated with poor sleep quality and may include excessive daytime sleepiness
and tiredness, as well as diminished concentration and memory loss.
Data storage and processing capabilities of the S8 ELITE system facilitate patient
management. The system provides summary data for a variety of time intervals, which
can be viewed via the LCD menus. The patient’s usage hours, treatment pressure,
mask leak, apnea + hypopnea index (AHI), apnea index (AI), and hypopnea index (HI)
are displayed in the Results section of the clinical menu. At your discretion, the patient
may view mask fit, treatment pressure, and usage hours for the last session. This patient
feature is called SMART DATA™.
You can download the data stored in the S8 ELITE and review it in a PC-based software
program. You can download the data directly, via cable. You can also access the data
remotely, using a RESSCAN™ Data Card. A patient’s therapy and reminder settings can
also be updated using the software. Patient data can be accessed and S8™ device
settings updated either via direct cable connection to the S8 ELITE or remotely, via a
Data Card.

USER/OWNER RESPONSIBILITY
The user or owner of this system shall have sole responsibility and liability for any injury
to persons or damage to property resulting from:
• operation which is not in accordance with the operating instructions supplied
• maintenance or modifications carried out unless in accordance with authorized
instructions and by authorized persons.
Please read this manual carefully before use.
This manual contains special terms and icons that appear in the margins to draw your
attention to specific and important information.
• Warning alerts you to possible injury.
• Caution explains special measures for the safe and effective use of the device.
• Note is an informative or helpful note.

INTRODUCTION 1
2
MEDICAL INFORMATION
INDICATIONS FOR USE
The S8 ELITE CPAP system is indicated for the treatment of obstructive sleep apnea
(OSA) in adult patients.
The S8 ELITE CPAP system is intended for home and hospital use.

CAUTION
! In the US, Federal law restricts this device to sale by or on the order of a physician.

CONTRAINDICATIONS
The S8 ELITE is not a life support device and may stop operating with power failure or
certain fault conditions. It should not be used by patients who are dependent on
continuous therapy.
Positive airway pressure therapy may be contraindicated in some patients with the
following pre-existing conditions:
• severe bullous lung disease
• pneumothorax
• pathologically low blood pressure
• dehydration
• cerebrospinal fluid leak, recent cranial surgery, or trauma.

WARNINGS
• The entire manual should be read before using the S8 ELITE.
• Advice contained in this manual should not supersede instructions given by the
prescribing physician.
• A patient should not connect a device to the data communication port unless
instructed to do so by their health care provider or physician. Only ResMed
products are designed to be connected to the data communication port.
Connecting other devices could result in injury, or damage to the S8 ELITE device.
• The S8 ELITE should only be used with masks (and connectors*) recommended by
ResMed, or by a physician or respiratory therapist. A mask should not be used
unless the S8 ELITE device is turned on and operating properly. The vent hole or
holes associated with the mask should never be blocked.
Explanation: The S8 ELITE is intended to be used with special masks (or
connectors*) which have vent holes to allow continuous flow of air out of the
mask.
When the device is turned on and functioning properly, new air from the device
flushes the exhaled air out through the mask vent holes. However, when the
device is not operating, insufficient fresh air will be provided through the mask, and

* Ports may be incorporated in the mask or in connectors that are near the mask.

MEDICAL INFORMATION 3
 the exhaled air may be rebreathed. Rebreathing of exhaled air for longer than
several minutes can, in some circumstances, lead to suffocation. This applies to
most models of CPAP devices.
• In the event of power failure or machine malfunction, remove the mask.
• The S8 ELITE can be set to deliver pressures up to 20 cm H2O. In the unlikely
event of certain fault conditions, pressures up to 30 cm H2O are possible.
• If oxygen is used with this device, the oxygen flow must be turned off when the
device is not operating.
Explanation: When the CPAP device is not in operation and the oxygen flow is
left on, oxygen delivered into the air delivery tubing may accumulate within the
CPAP machine enclosure and create a risk of fire. This applies to most types of
CPAP machines.
• Oxygen supports combustion. Oxygen should not be used while you are
smoking or in the presence of an open flame.
• Always ensure airflow is being generated by the device before the oxygen
supply is turned on.
• Always turn the oxygen supply off before stopping the airflow from the device.

Note: At a fixed rate of supplemental oxygen flow, the inhaled oxygen concentration
will vary, depending on where the oxygen is introduced, the pressure settings, patient
breathing pattern, and leak rate.
• Do not use the S8 ELITE if there are obvious external defects or unexplained
changes in performance.
• Do not open the S8 ELITE case. There are no user serviceable parts inside. Repairs
and internal servicing should only be performed by an authorized service agent.
• Explosion hazard—do not use in the vicinity of flammable anesthetics.

CAUTIONS
• At low pressures, the flow through the exhalation ports of your mask may not
clear all exhaled gas from the tubing. Some rebreathing may occur.
• The air flow for breathing produced by this device can be as much as 11°F (6°C)
higher than the temperature of the room. Caution should be exercised if the room
temperature is warmer than 90°F (32°C).

Note: The above are general warnings and cautions. Specific warnings, cautions, and
notes appear with the relevant instructions in the manual.

ADVERSE EFFECTS
Patients should report unusual chest pain, severe headache, or increased
breathlessness to their prescribing physician. An acute upper respiratory tract infection
may require temporary discontinuation of treatment.

4
The following side effects may arise during the course of therapy with the S8 device:
• drying of the nose, mouth, or throat
• nosebleed
• bloating
• ear or sinus discomfort
• eye irritation
• skin rashes
• chest discomfort.

OPERATING INFORMATION
PRINCIPLES OF OPERATION
The S8 ELITE system is designed for clinical use and home treatment of adult patients
with obstructive sleep apnea (OSA). The S8 ELITE device provides fixed-positive-
pressure room air via tubing to the mask worn by your patient. The continuous air
stream “splints” open the upper airway, preventing airway collapse.
The S8 ELITE delivers pressure within the range 4 to 20 cm H2O, depending on the
patency of the upper airway. To make the beginning of treatment more comfortable,
you may set a ramp so the pressure starts low and gradually increases to full treatment
pressure over the ramp time.
EXPIRATORY PRESSURE RELIEF
Note: EPR may not be available in all regions.
In the S8 ELITE, you can select expiratory pressure relief (EPR). EPR is designed to
maintain optimal CPAP treatment for the patient during inhalation and reduce the
delivered mask pressure during exhalation. The desired result of EPR is to decrease the
pressure the patient must breathe out against, making the overall CPAP therapy more
comfortable.
The features of EPR are:
• EPR is disabled automatically in the event of an apnea.
• EPR resumes automatically when the apnea event has passed.
• You can select an EPR pressure drop of OFF, 1, 2, or 3 cm H2O.
• You can set EPR to be off, delivered only during ramping, or delivered throughout
therapy.
• Pressure drop is limited, to avoid sub-optimal treatment (maximum drop is
3 cm H2O).
• When EPR is enabled, the delivered pressure will not drop below a minimum
pressure of 4 cm H2O, even if, for example, the set pressure is 6 cm H2O and the
EPR setting is 3.
• Either the clinician alone, or both the clinician and the patient can access the EPR
setting. You can enable or disable patient access to the EPR setting.
Note: When EPR is enabled, detection of apneas and hypopneas may become less
reliable at high levels of leak (> 0.4 L/s — 24 L/min).

SYSTEM SETUP
1 Place the S8 ELITE on a table near the head of the patient’s bed.
CAUTION
! Be careful to place the device where it cannot be bumped, and where no one will
trip over the power cord.
Note: The S8 Elite device may be placed on the floor beside or underneath the patient’s
bed. Ensure that the area is free from dust and clear of bedding, clothes, or any other
objects that could block the air inlet.

2 Connect the AC power cord or ResMed DC-12 converter (not supplied) to the
corresponding socket on the rear of the S8 ELITE (D-1). Plug the other end of the
power cord or adapter cable into the appropriate power outlet.
WARNING
! • Make sure the power cord and plug or adapter cable are in good condition and
the equipment is not damaged.
• In the clinical environment any personal computer that is used with your CPAP
system must be at least 5’ (1.5 m) away from, or at least 8’ (2.5 m) above, the
patient. It must also comply with the relevant test standard. For personal
computers the international standard is IEC 60950 or equivalent.

3 Connect one end of the air tubing firmly onto the air outlet of the device (D-2) and
the other end to the mask system (D-3).
When the S8 ELITE unit is powered up, the Welcome screen is displayed, followed by
the standby (RAMP) screen.
The S8 ELITE system is now ready for use (D-4).
Note: The S8 Elite uses an internal pressure sensor, and therefore does not require
calibration by a clinician or patient.

10
 SMARTSTART™
If you enable the SmartStart™ function, the patient’s device will start automatically
when they breathe into their mask, and will stop automatically when they take the
mask off. This means that the patient does not have to press the Start/Stop key to
begin or end treatment. See “Clinical Menu” on page 19 for details about enabling
SmartStart.
Note: A patient must not use SmartStart if they are using a mask with an anti-asphyxia
valve, such as the Mirage Full Face Mask.

DELIVERING THERAPY
WARNING
! A mask should not be used unless the S8 Elite is turned on and operating properly.

1 Ensure the patient settings are correct.

Instruct the patient to lie down in bed, arrange the air tubing, and put on the mask as
in steps 1 and 2 in the section “Using the Mask Fitting Feature” on page 12.

WARNING
! • Do not leave long lengths of air tubing around the top of the bed; they may twist
around the patient's head or neck while they are sleeping.
• Blocking the air inlet or tubing while in operation could lead to overheating of
the device.

2 Start therapy in one of two ways:

• If SmartStart is enabled, instruct the patient to breathe out strongly into the mask.
The S8 ELITE device will start automatically.
• If SmartStart is not enabled, press the Start/Stop key to start the airflow. Air will
begin flowing slowly and will build up to full operating pressure in about 15 to 25
seconds.
After starting therapy, the treatment pressure is displayed on the LCD.
Note: The S8 Elite measures pressure and compensates for air tubing and mask
characteristics. The LCD shows the intended delivery pressure. If necessary, you can use a
water manometer to take a more accurate reading.
If the patient has difficulty falling asleep with full pressure, select a Ramp time. The
airflow will start very gently while they fall asleep. The pressure slowly increases to full
operating pressure over the selected Ramp time.

3 Instruct the patient to put on the mask according to the mask user instructions.

4 Adjust the mask and headgear to achieve optimal fit.

5 At the end of the ramp period, the LCD will display the word ‘CPAP’.

OPERATING INFORMATION 11
 6 Stop therapy in one of two ways:
• Remove the mask, and press the Start/Stop key to stop airflow.
• If SmartStart/Stop is enabled, simply remove the mask and treatment will stop
automatically.

USING THE MASK FITTING FEATURE

The S8 ELITE mask-fit feature delivers air pressure for a three-minute period before
therapy begins for adjusting mask fit to minimize leak. It allows the patient to assess
mask fit at typical treatment pressure at the start of the night, when pressure delivered
is normally quite low.
The S8 ELITE system should be set up beside the patient’s bed with the air tubing and
mask system connected. (See “System Setup” on page 10.)

1 Instruct the patient to lie down in bed. If desired, place the tubing over the top of the
headboard to reduce drag on the mask.

WARNING
! Do not leave long lengths of air tubing around the top of the bed; they may twist
around the patient’s head or neck while sleeping.

2 Instruct the patient to put the mask on according to the mask user instructions.

3 Hold down the Start/Stop key on the control panel (see Figure 1, S8 Elite Keypad
and LCD, on page 15) for at least 3 seconds until pressure delivery starts and the
following screen appears:

MASK FIT: *****

excelnt
mask-fit star rating

Note: The mask-fit pressure is the set treatment pressure, or 10 cm H2O, whichever is
greater.

4 Adjust the mask, cushion, and headgear to achieve optimal fit.

* _ _ _ _ (Adjust mask) 0.42–0.49 24.7–29.9

_ _ _ _ _ (Adjust mask) ≥ 0.50 ≥ 30.0

Note: While using the mask-fit feature, the star rating values are indicative of the
instantaneous leak calculated over the last 10 seconds.
Smart Data (designed for the patient) also uses a star rating for mask fit. The Smart Data
star rating values correspond to 70th centile mask leak for the last session. A five-star
rating is displayed, for example, if the leak rate was less than 0.10 L/s for 70% of the
session.

5 After three minutes, the pressure will revert to the set pressure, and treatment will
begin.
• If you do not wish to wait three minutes, hold down the Start/Stop key for three
seconds and treatment will begin immediately.
• If you press the Start/Stop key briefly (ie, for less than three seconds), the device
will return to standby mode (the RAMP screen is displayed).

USING HUMIDIFIERS
Please refer to the illustration in section E of the illustration sheet, and your HumidAire 3i
manual.
The HUMIDAIRE 3i attaches to the front of the S8 ELITE to provide heated
humidification. No other accessories are required for its use.
Notes:
a. Make sure the water chamber of the HumidAire 3i is empty before you attach or
detach the humidifier.
b. Remove the connector plug on the S8 Elite before you attach the HumidAire 3i.
Reattach the connector plug firmly after you detach the humidifier.

EPR (EXPIRATORY PRESSURE RELIEF)
Note: EPR may not be available in all regions.
You can set the S8 ELITE to provide EPR (expiratory pressure relief). You may want to
set EPR for patients who find it difficult to exhale against positive airway pressure. EPR
provides a small reduction to CPAP during exhalation, reducing patient effort.
You can switch EPR off completely, set it for use during ramp only, or set it for full-
time use during therapy (including the ramp period).
There are three levels of EPR available, each level corresponding to different levels of
pressure relief. 1, 2, and 3 provide varying levels of EPR, with 3 providing the highest
level. You can also set EPR to OFF. You can either set the EPR level only, or you can
set the EPR level and enable patients to modify their level of EPR via the EPR SETTING
screen in the patient menus.
Figure 4 shows the main menu screens. The Settings menu is expanded in Figure 5.

SETTING REMINDERS
You can set a number of reminders to alert the patient to specific events; for example,
when to replace their mask, when to insert a Data Card (if their device is Data Card
enabled) and so on. You can also set special customized reminders.
When a reminder is due, a message is displayed on the LCD and remains whenever
the device is not delivering therapy. The backlight on the LCD flashes when a message
is displayed.
If more than one reminder for a patient is scheduled for the same date, all scheduled
reminders are displayed on that date. Patients can clear each message by pressing the
Left key (or inserting a Data Card, in the case of the Data Card reminder).
You access reminders from Clinical Menu, Options (see Figure 5, Settings menu
screens, on page 21). From the REMINDERS screen, scroll down to the submenus to
set a number of different types of message.
REPLACE MASK
You can set a timed reminder to remind a patient when they need to replace their
mask. The patient can press the Left (Ok) key to remove the message from the LCD.
CALL PROVIDER
You can set a timed reminder for your patient to phone you at a certain time; for
example, to discuss how their therapy is going. The patient can press the Left (Ok)
key to remove the message from the LCD.
INSERT CARD
If a patient’s flow generator is Data Card enabled, you can set a timed reminder on the
flow generator to remind them that they need to insert a Data Card to transfer patient
data. This enables you to establish compliance. The patient should actually insert the
Data Card in order to clear the message from the LCD. (They can also press the Left
(Ok) key to remove the message.)
REPLACE FILTER
You can set a timed reminder to remind your patient when to replace the air filter.
The patient can press the Left (Ok) key to remove the message from the LCD.

DATA MANAGEMENT USING THE MENUS
The S8 ELITE system may be used to monitor patient usage as well as treatment
pressure, mask leak, and incidence of apneas and hypopneas. To assess the patient’s
progress, data for the last session may be compared to median values for the last week,
the last month, the last six months, and the last year, as displayed in the Results menu.
The device stores usage and summary data for up to 365 sessions.
Comprehensive patient data can be viewed either on the LCD or in a PC software
application. Data and settings can be transferred between the S8 ELITE and the PC
application via S8 data management products. See “S8 Data Management Products”
on page 33.

CLINICAL MENU RESULTS

A comprehensive set of data (usage data and efficacy data) is available in Clinical Menu,
Results, as shown in Figure 7 on page 28.
To navigate within the Efficacy or Usage Data screens, use:
• the Up/Down key to scroll through items within a time series
• the Left key to navigate between time series.
The USED HRS screen reports the total hours the device has been used and the first
USAGE screen reports the number of sessions the device was used, compared to the
total sessions since the last time the compliance data was reset. Other USAGE screens
report statistical usage data.
Other statistics quoted include:
• pressure (95th centile value for mask-on time only)
• leak (95th centile value for mask-on time only)
• AHI: apnea + hypopnea index (calculated per session)
• AI: apnea index (calculated per session)
• HI: hypopnea index (calculated per session).

Statistics are provided for five time intervals (last day, last week, last month, last six
months, last year) so you can assess the significance of recent events.
All statistics calculated for a range of dates are median values. The median is the middle
value after the data have been sorted in order (50% of the values are smaller and 50%
are larger). For example, Table 6 presents one week of 95th centile leak data (values
in L/s). On day 7, the value 0.30 L/s would be displayed as the most recent day’s leak
value. In column 3 of the table, the seven leak values have been sorted in increasing
order to calculate the median value.
Table 6: Sample calculation of median leak value

95th centile leak Ordered data set Median value

Day
(L/s) (L/s) (L/s)

7 0.30 0.20

6 0.20 0.20

5 1.00 0.30

4 0.20 0.30 0.30

3 0.30 0.30

2 0.40 0.40

1 0.30 1.00

The median corresponds to the fourth value (0.30 L/s) in the ordered data set. The
value 0.30 L/s would be displayed as the most recent week’s leak value.
If the data set had included an even number of days (eg a 30-day month), the median
would be the average of the middle two values in the ordered data set.
Notes:
a. The median is a more robust measure than an average (or arithmetic mean) for a data
set that has some extreme values. The average of the data in the above table is
0.39 L/s, reflecting the single session that had unusually high leak (1.00 L/s).
b. You may make the Efficacy and Usage Data screens available to your patient by
instructing them to press the Left and Right keys simultaneously. This does not give
access to the other parts of the clinical menu.
The Erase Data feature in Clinical Menu, Options enables you to remove all efficacy
and usage data stored in the device (except Run Hours). Machine settings are not
affected.

DATA MANAGEMENT USING THE MENUS 29

 INTERPRETING DATA IN THE CLINICAL MENU
Note: When assessing results, check the leak data first. Leak values greater than 0.4 L/s
(24 L/min) affect the accuracy of other measurements.

PRESSURE
The pressure transducer located in the device measures treatment pressure; the
average pressure is calculated and recorded each minute. The pressure reported in the
Efficacy Data submenu (see Figure 7, The clinical menu results series, on page 28) for
a single session is the 95th centile pressure for mask-on time, excluding periods when
the leak has exceeded 0.4 L/s (24 L/min). For selected time intervals (last week, last
month, last six months, or last year), the median of the daily 95th centile values is
reported. Non-usage days are not included in calculations.

LEAK
Leak is derived by analyzing inspiratory and expiratory airflows (via the flow sensor
located in the device). Theoretically, inspiratory and expiratory volumes should be
equal. A net airflow greater than the expected mask vent flow is equal to the leak.
Generally, a leak rate of more than 0.4 L/s (24 L/min) is associated with patient
discomfort, disturbed sleep, and reduced efficacy of treatment.
Notes:
a. If the leak exceeded 0.4 L/s (24 L/min) for more than 30% of the previous session, the
following message will appear on the LCD: High leak in last session.
b. The Leak Alert feature, if enabled, will alert the patient when mask leak exceeds
0.7 L/s (42 L/min) for more than 20 seconds.
The leak reported in the Efficacy Data submenu (see Figure 7, The clinical menu results
series, on page 28) is the 95th centile value for mask-on time for each session, or the
median 95th centile value for a selected time interval (last week, last month, last 6
months, or last year). Non-usage days are not included in calculations.

APNEAS AND HYPOPNEAS

An apnea is defined as a greater than 75% decrease in ventilation. The device
algorithm scores an apnea if the 2-second moving average ventilation drops below 25%
of the recent time average (time constant 100 seconds) for at least 10 consecutive
seconds. A hypopnea is defined as a 50 to 75% drop in ventilation. A hypopnea is
scored if the 8-second moving average ventilation drops below 50%, but not below
25%, of the recent average for 10 consecutive seconds.
The AHI, AI, and HI reported in the Efficacy Data submenu are calculated values per
usage hour per session, or median values for a selected time interval (last week, last
month, last six months, or last year).
Note: When EPR is enabled, detection of apneas and hypopneas may become less
reliable at high levels of leak (> 0.4 L/s — 24 L/min).

30
SMART DATA IN THE PATIENT MENU
A SMART DATA feature has been incorporated in the S8 ELITE device to increase patient
involvement in their therapy. Display of SMART DATA for the patient to review is at
your discretion. Select some or all options for display in the patient menu from the
SMART DATA submenu in Clinical Menu, Options (see Figure 5, Settings menu screens,
on page 21). The following data can be made available, showing, for the most recent
session:
• the star rating of the 70th centile mask fit
• 95th centile pressure
• total duration of session (usage).

Set the Mask Fit, Pressure, or Usage options to ON to enable the patient to see any
or all of this data.
If the Auto Appear option is set to OFF, the data will be displayed in the Results
submenu of the patient menu only. If you (or the patient) set Auto Appear to ON, the
data for the previous session will be displayed after the patient restarts the device.
Data for the current session are available for display up until noon, when a new session
commences.
Note: If none of the Smart Data options (Mask Fit, Pressure, or Usage) has been set to
ON in the clinical menu, the Results submenu is not displayed in the patient menu.
Patients can use a Smart Data diary to monitor their therapy. You can download a PDF
of the Smart Data diary for S8 ELITE from <www.resmed.com>.

DATA MANAGEMENT USING THE MENUS 31

32
S8 DATA MANAGEMENT PRODUCTS
Note: Do not remove data management products from the S8 Elite while power is
connected.
The S8 ELITE will have one of two modules fitted to the back:
• blank module
• Data Card module.
Serial and USB adapters are also available, for transferring data to a PC.

USING A BLANK MODULE

The blank module is a protective cover on the S8 ELITE. At times, you may wish to
remove or attach the module, for example to use an adapter.
To remove the blank module, pull it off the back of the S8 ELITE to show the data
communications port (F-1).
To attach the blank module, push the blank module onto the data communications
port, until the module clicks into place (F-2).
Note: To protect the data communications port, always ensure there is a module
attached to the back of the device.

USING THE RESSCAN DATA CARD MODULE

The ResScan Data Card module is a convenient way of gaining remote access to the
data stored in the S8 ELITE, and of updating the settings in the S8 ELITE. The Data Card
module is for home and hospital use. This module uses the ResScan Data Card for data
collection and transmission.
Note: Patient compliance data stored in the S8 Elite remains unchanged when copied to
the Data Card.
If a patient has an S8 ELITE with a Data Card module attached, they can use a Data
Card to retrieve data or update settings that are stored in the S8 ELITE.
If a patient has an S8 ELITE with a blank module attached, and they need to use a Data
Card, you can order a Data Card starter pack from ResMed. This pack contains a Data
Card module and Data Card.
1. Remove the blank module from the S8 ELITE (F-1).
2. Attach the Data Card module to the S8 ELITE (G-1).
3. Follow the instructions for inserting the Data Card (page 36).

PATIENT MANAGEMENT OF THE DATA CARD

CAUTION
! Always supply the Data Card and mailback envelope in the supplied bubble mailer
envelope to protect the Data Card during transport. Advise the patient to use the
bubble mailer when returning the Data Card and mailback envelope by mail.

S8 DATA MANAGEMENT PRODUCTS 33

 Before issuing the Data Card, make sure that it has been labeled with the patient’s ID
and that the bubble mailer is correctly addressed. Refer to “Using the Mailback
Envelope and Bubble Mailer” on page 35 for more details.
Check that the patient knows:
• why they are being issued with a Data Card
• when and how they must use the Data Card
• how to insert the Data Card
• how to remove the Data Card
• how to return the Data Card
• where to look for information (the “Troubleshooting” section of the User’s Manual
for their S8 device) if the data transfer does not work as expected.

LABELING THE DATA CARD

• We strongly advise that you write the patient’s identification details on the Data
Card to prevent any mix-up of patient data. A space is provided on the Data Card
for this purpose.
• Each Data Card is reusable. If you are issuing an existing Data Card to a new
patient, make sure that the card is labeled with the new patient’s ID. Use the space
provided on the Data Card label when issuing a new card.
Notes:
a. When reusing a Data Card, make sure that you use a label that does not cover more
than the ID area on the Data Card, and is not more than 0.078” (0.2 mm) thick. If the
label is larger than this, the patient may not be able to insert the Data Card into the
Data Card module on their flow generator.
b. If you reuse a Data Card that already has a label on it, remove the old label before
attaching a new one.

SUPPLYING THE DATA CARD

The patient may be given a blank Data Card when they receive an S8 ELITE with a Data
Card module attached, or if they subsequently have their S8 ELITE modified to use Data
Cards.
If you want to monitor a patient’s treatment, you can give or mail them a blank Data
Card with a mailback envelope. The patient can return the card to you when they have
copied their data onto it. If you are mailing the Data Card, you need to advise the
patient when the card is being mailed out to them.
If you want a patient to update the settings in their S8 ELITE, you can load the new
settings on to a Data Card and either give or mail them the card with a mailback
envelope. The patient can return the card to you when they have applied the settings
on their S8 device. The information on the card will allow you to assess whether the
patient’s settings have been changed as expected.
Notes
a. The Data Card should be stored in its mailback envelope when not in use.
b. Use a postal envelope to mail the bubble mailer and its contents to the patient.

34
USING THE MAILBACK ENVELOPE AND BUBBLE MAILER
The Data Card slots into the mailback envelope to keep it safe while in transit or
storage.
Figure 8 shows the inside of the mailback envelope.
