Blood pressure function test & calibration check
Note:
Ensure the NIBP cuff is not around a limb whilst performing the calibration check.
Inspect the Blood Pressure cuff, hose and connectors for damage. Replace any parts that are
worn out or frayed.
The pressure measurement accuracy may be checked against a calibrated mercury, aneroid or
digital manometer.
It is recommended that pressure measurement accuracy is performed annually. To do this
perform the following:
Apparatus required:
1. Calibrated manometer
2. Tubing, “T” connectors and inflation
bulb.
3. An arm sized cylindrical object to wrap
the cuff around.
Method:
1.
Connect the apparatus
2.
From the Welcome Screen, select the Blood Pressure button.
3.
Click “Sphyg mode”
4.
Inflate the cuff using the inflation bulb.
5.
Compare D-MAS pressure reading with the calibrated manometer.
6.
If the pressure remains above 15mmHg for a period of 120 seconds, a safety
feature will operate and the pressure will be reduced to zero.*
7.
If the readings do not agree closely (within 3 mmHg) please call for technical
assistance or refer the D-MAS to qualified technical personnel.
