2. Before inflation, the reading on the manometer should be zero. If not, open the valve of the squeeze bulb to let the
whole airway open to the atmosphere. Close the valve after the reading turns to zero.
3. Select Main Menu→Maintenance→enter the required password→Module→NIBP→NIBP Accuracy Test.
4. Check the reading of the manometer and the reading of the patient monitor. Both should be 0 mmHg.
5. Raise the pressure in the rigid vessel to 50 mmHg with the squeeze bulb. Then, wait for 10 seconds until the
measured values become stable.
6. Compare the reading of the manometer with the reading of the patient monitor. The difference should be 3 mmHg.
If it is greater than 3 mmHg, contact your service personnel.
7. Raise the pressure in the rigid vessel to 200 mmHg with the squeeze bulb. Then, wait for 10 seconds until the
measured values become stable. Repeat step 6.
You can use an NIBP simulator to replace the squeeze bulb and the reference manometer to perform the
test.
You can use an appropriate cylinder and a cuff instead of the rigid vessel.
