NIBP Valve, Pump, and Tubing Integrity Tests
9650-0804-01 Rev. A ZOLL Propaq M Service Manual 13
NIBP Deflation Test
Equipment Single lumen BP hose, a 500 cc volume, a timer, and a calibrated manometer (optional).
Note: Note: If a 500 cc volume is not available, an Adult BP cuff wrapped around a rigid
cylinder (such as a glass jar) will suffice.
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 cuff wrapped around a rigid cylinder, such as a glass
jar. If available, connect a calibrated manometer to the air line using a T-fitting.
3. On the Propaq M, do the following to enter 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 NIBP Test control panel or the external pressure
standard.
6. Select Turn Pump Off as soon as the pressure reaches the target pressure of 265 +/- 5 mmHg.
7. Allow the system to stabilize for 5 seconds.
8. Use the navigation keys to select Open Valve and immediately start the timer.
9. Stop the timer as soon as pressure drops below 15 mmHg.
10. Record the Deflation Time as T
D
.
Acceptable Results
The unit passes the test if the time to release pressure from 265 +/- 5 mmHg to 15 mmHg is less
than 10 seconds.
Corrective Action
If the unit fails the test, the most likely cause is kinked or obstructed internal tubing, or
obstructed filter. The device needs to be disassembled to replace or reposition the appropriate
segment of NIBP tubing.
