Overview
Preface—Contains safety warnings and an overview of the manual’s contents. Be sure to
review this section thoroughly before attempting to use or service the Propaq M unit.
Preface
ZOLL® Medical Corporation’s Propaq® M Service Manual is intended for the trained
biomedical technician whose responsibility is to identify malfunctions and/o r make repairs at
the subassembly level. The Propaq M Service Manual has six main sections and two
appendixes.
Chapter 1—Maintenance Tests describes the Annual Calibration Tests for NIBP and EtCO
modules, Functional Tests that need to be run when a module has been repaired, and
Operational Tests that need to be performed at regular intervals to augment the automatic
testing the Propaq M does to ensure readiness.
Chapter 2—Troubleshooting provides a listing of error messages to help the service
technician detect faults and repair them.
Chapter 3—Disassembly Procedures describes step-by-step procedures for removing
subassemblies from the Propaq M unit.
Chapter 4—Life Cycle Counters describes step-by-step procedures for setting life cycle
counters after replacing modules in the Propaq M unit.
Chapter 5—Replacement Parts List displays a complete list of ZOLL part numbers for field
replaceable parts available for the Propaq M unit, allowing the service person to identify and
order replacement parts from ZOLL.

Safety Considerations
The following section describes general warnings and safety considerations for operators and
patients. Service technicians should review the safety considerations prior to servicing any
equipment and read the manual carefully before attempting to disassemble the unit. Only
qualified personnel should service the Propaq M unit.
Federal (U.S.A.) law restricts this unit for use by or on the order of a physician.
Safety and effectiveness data submitted by ZOLL Medical Corporation to the Food and Drug
Administration (FDA) under section 510(K) of the Medical Device Act to obtain approval to
market is based upon the use of ZOLL accessories such as patient cables and batteries.
Only qualified personnel should disassemble the Propaq M unit.
Do not discharge a battery pack except in a ZOLL SurePower
Do not use the Propaq M in the presence of flammable agents (such as gasoline), oxygen-rich
atmospheres, or flammable anesthetics. Using the unit near the site of a gasoline spill may
cause an explosion.
Do not use the unit near or within puddles of water.
Additional Reference Material

Propaq M Overview
This chapter includes step-by-step procedures for the following types of maintena nc e tests:
• Calibration and Calibration Checks
• NIBP Valve, Pump, and Tubing Integrity Tests
• Operational Tests
• Functional Verification Tests
At a minimum, a trained biomedical technician must perform a CO
calibration check once per year. A CO

The Troubleshooting chapter in this manual may recommend performing one of more of the
NIBP valve, pump, and tubing integrity tests to help identify and correct potential issues with
the NIBP valve, pump, and/or tubing.
It is necessary to perform Functional Verification Tests after a module is repaired to en sure that
the functions of the Propaq M unit work properly.

Because the Propaq M units must be maintained ready for immediate use, it is important for
users to conduct the Operator’s Shift Checklist procedure at the beginning of every shift. This
procedure can be completed in a few minutes and requires no additional test equipment. (See
the ZOLL Propaq M Operator’s Guide for the Operator’s Shift Checklist.) It is highly
recommended that the Operational Tests be performed at regular intervals to augment the
automatic testing the Propaq M does to ensure readiness.

Calibration and Calibration Checks
NIBP Calibration Check
Equipment Single lumen BP hose, a 500 cc volume, and a calibrated manometer or pressure gauge
(< = 1mmHg accuracy). If a 500 cc volume is not available, an Adult BP cuf f wrapped around a
rigid cylinder (such as a glass jar) will suffice.
Note: This test is to be performed for the following target pressures: 50 +/- 5 mmHg,
150 +/- 5 mmHg, and 250 +/- 5 mmHg.
Procedure
1. Power on the Propaq M.
2. Connect the Propaq M to the single lumen hose and the 500 cc volume. Alternatively , replace
the 500 cc volume with a standard Adult cu ff wrapped around a rigid cylinder , such as a glass
jar. Connect a calibrated manometer to the air line using a T-fitting.
3. On the Propaq M, do the following to ent er the NIBP Test control panel:
• Press the Setup quick access key ().
• Use the navigation keys to select Supervisor>Service>Device Tests>NIBP Test.
4. From the Propaq M NIBP Test control panel, use the navigation keys to select:
• Close Valve
• Turn Pump On
5. Monitor the pressure reported by the external pressure standard.
6. Once the pressure reaches the target pressure of 50 +/- 5 mmHg, use the navigation keys to
select Turn Pump Off.
7. Allow the system to stabilize for at least 10 seconds.
8. Record the pressure reported by the external pressure standard as P
9. Record the pressures reported by the primary and safety transducers (displayed in the NIBP
Test control panel) as P

Equipment Single lumen BP hose, a 250 cc volume, a timer, and a calibrated manometer (optional).
Procedure
1. Power on th e Propaq M.
2. Connect the Propaq M to the single lumen hose and the 250 cc volume. If available, connect
a calibrated manometer to the air line using a T- fitting.
3. In the Propaq M, do the following to enter the NIBP Test control panel:
4. Press the Setup quick access key ( ).
5. Use the navigation keys to select Supervisor>Service>Device Tests>NIBP Test.
6. Wait 10 seconds to allow the system to vent any residual pressure.
7. Verify that the pressure reported by the NIBP Test control panel or the external pressure
standard system is less than 5 mmHg.
8. From the NIBP Test control panel, use the navigation keys to select Close Valve.
9. Select Turn Pump On and immediately start the timer.

Note: Note: The pump will automatically turn off if pressure ex ceeds 3 10 mmHg during this
test.
Acceptable Results
The unit passes the test if the time to increase pressure to 210 mmHg is less than 7 seconds.
Corrective Action
If the unit fails the test, the most likely cause is a faulty pump or a kinked internal hose. The
device needs to be disassembled to replace the pump or reposition the appropriate segment of
NIBP tubing.
