12.4.2 Testing for Air Leakage
The PNEUMATIC option is used to test air leakage. When the NIBP cuff is connected, select this
option to start the NIBP inflation and test whether the air leakage occurs in the airway. If the test
is passed, no prompt information will be displayed; if the test is not passed, corresponding
prompt information will be displayed in the NIBP parameter window.
To test air leakage, use the following procedure:
1. Set PAT TYPE to ADU.
2. Connect a rigid metal container or vessel with a capacity of 500 ml ± 5% to the NIBP cuff
connector of the monitor.

3. Select the PNEUMATIC option, and the information “Pneum testing…” is displayed at the
lower left corner of the NIBP parameter window.
4. After approximately 20 seconds, the monitor will automatically open the deflate valve,
ending the test.
5. If no information appears on the bottom of the NIBP parameter area, it indicates the airway
is in good condition and an air leak does not exist. However if the information
“PNEUMATIC LEAK” appears, it indicates the airway may have an air leak. In this case,
check for loose connections. After confirming all connections are secure, perform the test
again.
If there is still a failure, contact our Customer Service.
NOTE
z Set PAT TYPE to ADU in the PATIENT SETUP menu before leakage test.
z The pneumatic test, other than being specified in the EN 1060-1 standard, is to
be used to simply determine whether there are air leaks in the NIBP airway.
