NIBP Valve, Pump, and Tubing Integrity Tests
NIBP Leak Test
Equipment Single lumen BP hose, a 500 cc volume, and a calibrated manometer.
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 100 cc volume. Alternatively, replace
the 100 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 NIBP Test control panel or the external pressure standard.
6. Select Turn Pump Off as soon as the pressure reaches the target pressure of 250 +/- 5 mmHg.
7. Allow the system to stabilize for 10 seconds.
8. Select Mark P1 to mark the starting pressure. If available, measure the starting pressure
reported by the external pressure standard. Record the starting pressure as P
S
.
9. Wait 15 seconds.
10. .Select Mark P2 to mark the ending pressure. If available, measure the ending pressure
reported by the external pressure standard. Record the ending pressure as P
E
.
11. From the NIBP Test control panel, select Open Valve to release the pressure.
12. Calculate the leak rate: L = (P
s
- P
e
) / (15 seconds).
Note: If using the pressure reported in the NIBP Test control panel, calculate the Leak Rate
using the Primary transducer pressures.
Acceptable Results
The unit passes the test if the system leaks less than 5 mmHg over the 15-second time interval
(Leak Rate is less than 1/3).
