Preventative Maintenance Tests

Testing the Monitor  

The following table lists the tests that should be documented and summarizes how to 
document the NBP test results.

Pressure Transducer Accuracy Test

X1 = difference between the pressure on 
the monitor and on the simulator

Difference less than or equal to 5 
mmHg (0.7 kPa)

PN:P/X1/X2/X3/X4/X5

or 

PN:F/X1/X2/X3/X4/X5

P = passed, F = failed

Pneumatic Leakage Test

X2 = difference between the pressure at 
the start (P1) and after one minute (P2)

Difference less than or equal to 6 
mmHg (0.8 kPa)

Inflation Rate Test

X3 = number of seconds for the monitor 
to inflate

Rate between 1 and 6 seconds

Over-Pressure Test

X4 = peak value 

Peak value between 270 and 330 mmHg 
(36 kPa and 44 kPa)

Deflation Rate Test

X5 = mmHg (kPa) per second to deflate 

1.8 mmHg/s to 4.8 mmhg/s
