5.4.2 Checking the
pressure gauge
accuracy
The accuracy of the airway pressure gauge can be checked by using
the following:
•
a low-pressure test device (digital manometer or test gauge) with
an accuracy of ±2% of reading.
•
a low-pressure supply source (typically a syringe).
•
and an airway pressure gauge test adapter.
1.
Ensure that the pressure gauge is zeroed (Section 5.4.1).
2.
Remove the table top.
3.
Remove the existing tube to the airway pressure transducer on
the control sample board and connect a low pressure test device
to the remaining open tube.
4.
Remove the existing tube to the common gas port and connect a
low-pressure supply source (syringe) to the remaining open tube.
5.
Adjust the pressure source to the following pressures as read on
the airway pressure gauge. The test device gauge should read
within the values indicated.
