Introduction 1
Introduction
The Fluke Biomedical BP Pump 2 Non-Invasive Blood Pressure Simulator and
Tester, hereafter known as the Tester, is a multi-purpose test instrument for
use with oscillometric Non-Invasive Blood Pressure Monitors (NIBPMs). The
Tester provides dynamic blood pressure simulations, static calibration,
automated leak testing, and pressure relief valve testing. The following
models are available:
BP Pump 2L (Basic Model)
BP Pump 2M (High-Accuracy Model)
The Tester allows you to verify the performance claims of different blood
pressure monitors. You can quickly recall the fixed onboard simulations or
define your own. With its internal pump, the Tester can generate pressures up
to 400 mmHg (53.3 kPa) for leak testing, pressure sourcing, and relief valve
testing.
In addition, you can define auto sequences that automate the sequencing of
tests and NIBP simulations and provide an optional printed report.

Key Features
Key features of the Tester include:
Pressure leak testing on cuff, tubing, and connections
Relief valve testing on the patient monitor
Pressure gauge measurements
Pressure source capability
NIBP simulations including adult, neonate, arrhythmias, and respiratory
artifacts

General Safety Considerations 1
Warnings and Cautions
Users are advised to read the manual carefully, observing all warnings and
cautions, before attempting to set up and operate the Tester.
A Warning identifies hazardous conditions and actions that could cause
bodily harm or death.
A Caution identifies conditions and actions that could damage the Tester or
the equipment under test, or cause permanent loss of data.

W X Warning
To avoid possible electric shock or personal injury, follow
these guidelines:
Read the Users Manual before operating the Tester.
Use this Tester only in the manner specified by the
manufacturer or the protection provided may be
impaired.
Do not connect the Tester to a patient or equipment
connected to a patient. The Tester is intended for
equipment evaluation only and should never be used
in diagnostics, treatment or in any other capacity
where the Tester would come in contact with a patient.
Do not use the product in wet locations, around
explosive gases or dust.
Never open the Tester case, because dangerous
voltages are present. There are no user replaceable
parts in the Tester.
The Tester must be properly earthed. Only use a
supply socket that has a protective earth contact. If
there is any doubt as to the effectiveness of the supply
socket earth, do not connect the Tester.
Do not use a two-conductor adapter or extension cord;
this will break the protective ground connection.
Ensure that the external power source is properly rated
for the system.

1-5
BP Pump 2
Operators Manual

Always connect the system power cord directly to a

three-prong receptacle with a functional ground. Never
use a two-prong plug adapter to connect primary
power to the Tester, thereby disconnecting the utility
ground.
Disconnect the Tester from the power source before
changing the supply voltage. The Tester operates at a
range of 100 to 240 volts.

W Caution
To avoid damage to the Tester or adverse affects on its
performance, follow these guidelines:
Allow only qualified technical personnel to service the
Tester.
Do not expose the system to temperature extremes.
Ambient temperatures should remain between 15 C
and 40 C. System performance may be adversely
affected if temperatures fluctuate above or below this
range.
Clean the Tester only by gently wiping down with a
clean, lint-free cloth dampened with a mild detergent
solution. Do not immerse the unit.
Do not apply pressures greater than 400 mmHg (53
kPa) to the pressure port.

Introduction 3
Introduction
The Tester contains a microprocessor that reads and controls the front panel
keyboard, the display, serial port, printer port, a diaphragm pump, two solenoid
valves, a step motor, a position sensor, and a pressure transducer (Figure 3-1).

Figure 3-1. Tester Pneumatic Block Diagram

The diaphragm pump is used as a pressure source for the relief valve, leak, and
pressure source tests. The diaphragm pump pulls air through a filter and forces it
through a check valve into the main manifold of the instrument. This main
manifold has an internal volume of approximately 20 cc and is directly connected
to the pressure port on the front panel. Pressure in the manifold is measured by a
pressure transducer and can be released by a solenoid-operated valve. The volume
of the main manifold can be increased by approximately 290 cc, to simulate an
adult pressure cuff, by opening a second solenoid valve.
A stepper motor and lead screw move a piston into the manifold to decrease the
manifold volume, thereby creating pressure pulses to simulate a human subject. A
seal around the piston is maintained by a rolling diaphragm seal. The size and

3-3
BP Pump 2
Operators Manual

shape of the pulses are controlled by the microprocessor driving the step motor.
The home position of the piston is detected by an optical interrupter. If the
optional high-accuracy pressure sensor is installed, it also measures the pressure in
the main manifold and is also controlled by the microprocessor.

Configurations for Devices Under Test (DUT)

Connect the Tester to the NIBPM unit with the tubing and fittings (part number
2391882) supplied with the Tester in the desired configurations, as shown in
Figures 3-2 through 3-6.
Basically, configurations involve connecting the NIBPM unit to the Tester directly
or connecting the unit, a cuff, and the Tester, using a T connector. When
connected properly, the tubing forms a closed system with the components.

5. Press the <START> soft key to make the Tester deliver air to the system.
Once the system under test reaches the target pressure, the test begins. The
pressure leak rate of the system and the current system pressure are shown
during the test. The leak rate is expressed in mmHg/min by default or can
appear in kPa/min, cmH2O/min, inH2O/min, or psi/min, depending on the
pressure measurement unit selection. The leak rate of the Tester is < 2
mmHg/minute.

Note
When testing with an NIBP monitor in the system, it is necessary to put
the monitor in Service mode, because most monitors leave the system
open to the atmosphere.
6. Press HOME to return to the Main menu.

Pressure Relief Test

The Pressure Relief Test increases the pressure in the pneumatic system until the
relief valve on the NIBP monitor opens, or until the Setpoint is reached, whichever
occurs first.

 Operation
Pressure Tests 3
Note
It is recommended that three pressure relief measurements be taken to
check for a sticky relief valve.
Some NIPB monitors do not allow access to a Service mode, rendering
it impossible to close a vent valve so that the system can be pressurized
by an outside pump. As a last resort, it is possible to start a blood
pressure determination with the monitor (this closes the valve), then start
the Pressure Relief tests, so that two pumps inflate the system. The results
can vary, but the monitor generally opens a relief valve at some high
pressure.
6. Press HOME to return to the Main menu.

Pressure Source Test

The Pressure Source Test enables the Tester to simultaneously generate and
measure pressure.
The Pressure Source Test can be used for static calibration of Non-Invasive blood
pressure monitoring systems, checking sphygmomanometers, and evaluating any
medical device that measures pressure in the ranges of 50 to 400 mmHg (6.7 to
53.3 kPa). Pressures can be generated in 1-mmHg (0.1 kPa) increments.

These waveforms cause erratic readings on some NIBPMs. The blood pressure
determination strongly depends on exactly what is happening with the subject's
blood pressure when the cuff pressure is at a particular level. Some NIBPMs
pause until they detect two or more equivalent beats. The pattern of step deflations
and the measured blood pressure depend on which beats occur during each step of
the cuff pressure.

Ansur Software Control

Ansur test automation systems allow a solutions-based approach to complete
testing of the medical device under test (DUT). Ansur helps you create standard
work using the test template/sequence (which is based on your written test
procedure) and integrates all test results into a single test report that can be printed
or archived. Ansur manages your test procedures by allowing both manual and
visual automated test sequences.
The software works hand-in-hand with Fluke Biomedical testers and simulators,
creating a seamless integration for:

Visual inspections
Preventive maintenance
Work procedures
Performance tests
Safety tests

3-29
BP Pump 2
Operators Manual

Ansur software utilizes plug-in modules to work with a wide array of Fluke
Biomedical instruments. The plug-in module is a software interface to the Ansur
program. Plug-ins provide test elements used by Ansur. This gives the benefit of
using the same user interface for all testers and simulators supported by an Ansur
plug-in. See the Fluke Biomedical Ansur BP Pump 2 Plug-in User Manual for
detailed information.
When you purchase a new Fluke Biomedical tester or simulator, you can update
your existing Ansur software by installing a new plug-in. Each plug-in module
lets you work only with the options and capabilities you need for the instrument
you are testing. The Fluke Part Number for the Ansur BP Pump 2 Plug-in is
2755836.

Questions and Answers

Introduction
The following are questions submitted by customers and answered by
members of our technical staff.

Blood Pressure Issues

Q: Monitor's BP determinations vary.
I connected the Tester to my Critikon DINAMAP monitor and used the preset
blood pressure of 120/80 (93) with a pulse rate of 80 beats per minute. I
performed three blood pressure determinations with the following results:
Trial # Systolic Mean Diastolic Pulse Rate
1 123 97 82 79
2 126 93 81 81
3 123 97 83 78

Why does the blood pressure determined by the DINAMAP vary?

A: Some variance is normal and acceptable.
The Tester generates a very repeatable simulation. For this simulation, an ideal
NIBP monitor would show a variation of less than 2 mmHg from one
simulation to the next. Most of the variation seen here originates in the
DINAMAP. This is normal and acceptable.
Section 3.4.3 of the ANSI Standard for Electronic or Automated
Sphygmomanometers specifies the required efficacy of the blood pressure
determination:

B-1
BP Pump 2
Operators Manual

The mean difference of the paired measurements of the test system and the
comparison system shall be 5 mmHg or less with a standard deviation of
8 mmHg or less.
This means that variations in individual readings of 5, 6, or even 10 mmHg are
quite normal and do not indicate that either the DINAMAP or the Tester are
malfunctioning. Some monitors are more repeatable than others, and
repeatability is one measure of the overall quality of the monitor.
Q: BP results vary using the same preset pressure.
I checked another NIBP monitor using the same preset simulated blood
pressure of 120/80 (93) with a pulse rate of 80 bpm. This time I got the
following results:
Trial # Systolic Mean Diastolic Pulse Rate
1 120 89 71 80
2 120 87 73 80
3 121 91 72 80

Why does this monitor show such low Diastolic pressures?

A: Monitors using different references Ascultatory vs. Invasive data.
Neither the monitor nor the Tester is broken or giving incorrect readings.
Some monitors were designed to give readings close to those obtained by the
Ascultatory method of blood pressure determination. Other monitors have been
designed to agree with Invasive Blood Pressure readings. It is well known that
Invasive and Ascultatory BP readings on the same subject can be quite
different. Therefore it is not surprising that automated Oscillometric NIBP
monitors using Invasive readings as a reference would give different readings
than a monitor based on Ascultatory readings.

Cuff Issues
Q: Why is an Internal Cuff used?
Why does the Tester use an Internal Simulated Cuff? Wouldnt it be better to
include a real cuff in the measurement?
A: Internal Cuff produces accurate and repeatable simulations.
The Tester uses an internal cuff to help ensure accurate and repeatable
simulations over time. The internal cuff is a 310-ml fixed volume that has
compliance very nearly equal to a normal adult cuff when used at typical adult

B-2
 Appendices
Questions and Answers B
mean pressures. Further, its compliance is constant over time and is
independent of cuff wrapping technique.
The compliance of a standard cuff depends on the amount of air it contains.
This, in turn, is dependent on what the cuff is wrapped around, and how tightly
it is wrapped.
Q: Why is compliance Important?
Why is tightly controlled compliance so important?
A: Air in the cuff affects oscillations.
Blood pulsing through the arm surrounded by a cuff actually causes
displacement of the air in the cuff. This must be converted into a pressure
oscillation before the NIBP monitor can sense what is happening.
For a given volume displacement, the size of the pressure oscillation is
inversely proportional to the volume of air in the cuff. Thus, a cuff full of air
gives a smaller pressure oscillation than one wrapped tightly around the arm
and containing little air.
The Tester works just like the subjects arm. It creates a precisely controlled
volume displacement. The cuff is what converts this displacement into a
pressure oscillation.
By using an internal cuff of fixed volume, the Tester is assured of always
producing the same pressure oscillation for each test.
Q. Can an External Cuff be used with the Tester?
Can the Tester be used with an External Cuff?
A. Connectors provided in Accessory Kit
The Tester can easily be configured to work with an External Cuff.
The available cuff options are accessible via the CUFF soft key present during
the NIBP simulations.

Note
The exceptions are neonate, which allows only the internal neonate
cuff, and wrist cuff, which allows only the external cuff.
The external cuff is included in the pneumatic circuit using the Tee or Y
connectors in the accessory kit.

Computer Control Commands

Introduction
The following commands are for use by software developers that have highly-
developed technical knowledge. Operators should not try to control the Tester
using these commands; rather, they should use Ansur test automation software.
The Tester acknowledges each valid computer control command that it
receives. It responds to valid commands either with ACK (HEX 06), or ACK,
followed by the data, followed by CR-LF (HEX 0D0A). A NAK (HEX 15) is
returned for invalid commands.
The computer control commands are shown in Table D-1.
