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 cuff 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 cuff 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 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 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
a
.
9.
Record the pressures reported by the primary and safety transducers (displayed in the NIBP
Test control panel) as P
p
and P
s
, respectively
10.
Calculate the absolute pressure differences between the applied pressure (P
a
) and each of the
transducer pressures.

d-Primary
= abs(P
a
-P

)
•

)
11.
From the NIBP Test control panel, select Open Valve to release the pressure
12.
Repeat steps 3 to 11 to test for the remaining target pressures of 150 +/- 5 mmHg and 250 +/
- 5 mmHg.
13.
Once complete, use the navigation keys to select Update NIBP Cal Check Date to save the
date of the most recent calibration check.
