5.3.6.2 NIBP Leakage Test
NOTE
You should perform the NIBP leakage test before any other NIBP test.
Tools required:
NIBP cuff for adult patient
Appropriate tubing
Rigid cylinder
Follow this procedure to perform the test:
1. Set [Patient Cat.] to [Adu].
2. Connect the NIBP cuff to the NIBP connector on the monitor.
3. Wrap the cuff around the cylinder as shown below.
4. Select [Main Menu]→ [Maintenance >>]→ [User Maintenance >>]→ enter the required password→ [Module
Maintenance>>]→[NIBP Leakage Test]. The message [Leakage Testing…] is displayed in the NIBP parameter area.
5. The cuff automatically deflates after 20s, which means NIBP leakage test is completed.
If no message is displayed in the NIBP parameter area, it indicates that the system does not leak. If the message [NIBP
Pneumatic Leak] is displayed, it indicates that the system may have a leak. In this case, check to make sure the NIBP cuff,
hose and connectors are not leaking and perform the test again.
You can also perform a manual leak test:
1. Perform procedures steps 1 to 4 in the NIBP Accuracy Test.
2. Raise the pressure in the rigid vessel to 250 mmHg with the squeeze bulb. Then, wait for 5 seconds to let the measured
values becoming stable.
3. Record the current pressure value, and then, record the pressure value after 60s.
4. Compare the two pressure values and make sure the difference is not greater than 6 mmHg.
