4.4.2 NIBP Test
Leakage Test
NOTE
Perform NIBP leakage test before any other NIBP concerned test and calibration.
Tools required:
NIBP cuff for adult patient
Air tubing
Cylinder
Follow this procedure to perform the leakage test:
1. In the [Patient Demographics] menu, set [Patient Cat.] to [Adu].
2. Connect the NIBP cuff to the NIBP connector on the monitor.
3. Apply the cuff to the cylinder as shown below.
4. Select [Main
→
][Maintenance >>
→
][NIBP Leakage Test]. The message [Leakage
Tes ting…] is displayed in the NIBP parameter area.
After about 20 seconds, the monitor will automatically deflate. This means the test is
completed. If no message is displayed in the NIBP parameter area, it indicates that the
system has no leakage. If the message [NIBP Pneumatic Leak] is displayed, it indicates that
the system may have a leakage. Check the tubing and connections for leakages. If you
ensure that the tubing and connections are all correct, perform a leakage test again. If the
problem persists, contact your service personnel.
You can either perform a manual leakage test:
1. Perform steps 1 to 4 in the NIBP Accuracy Test section.
2. Raise the pressure in the rigid vessel to 250 mmHg with the balloon pump. Then, wait
for 5 s to let the measured values becoming stable.
3. Record the current pressure value, and meanwhile use a time counter to count the time.
Then, record the pressure value after 60 s.
4. Compare the two pressure values and make sure the difference should not be greater
than 6 mmHg.
