To check the pneumatic system and valve:
IBP Test
This test checks the performance of the invasive blood pressure measurement.
To perform this test, you need a patient simulator such as the Foss Systems BP28.
To perform the IBP test:

Chapter 4, “Troubleshooting.”
Step
Step
1
In the NBP Test menu, select the Start Static Pressure Test button.
2
Squeeze the manometer pump to apply a pressure of 280 mmHg.
3
Wait 10 seconds for the pressure to stabilize. Note the pressure value in
the NBP Test menu.
Note — Philips employees record this value as P1.
4
Wait 60 seconds for the pressure to stabilize. Note the pressure value in
the NBP Test menu.
Note — Philips employees record this value as P2.
5
Calculate and document the leakage test value. The leakage test value
should be less than or equal to 6 mmHg.
Note — Philips employees record this value as X3 (where X3 = P1 - P2).
6
Select the Stop Static Pressure Test to stop the process.
7
If the leakage test value exceeds 6 mmHg, check the test setup cuff and
tubing, and then test again. If the test still fails, check the pneumatic
tubing inside the monitor.
8
If you cannot eliminate the leak, see Chapter 4, “Troubleshooting.”
