23.6 NIBP Accuracy Test
The NIBP accuracy test is required at least once a year or when you doubt the measured NIBP.
Tools required:

T-piece connector

Approprating tubing

Balloon pump

Metal Vessel (volume 500±25 ml)

Reference manometer (calibrated with accuracy equal to or better than 0.75 mmHg)
Follow this procedure to perform the accuracy test:
1. Connect the equipment as shown.
2. Before inflation, check that the reading of the manometer should be 0. If not, open the valve of the balloon pump
to let the whole airway open to the atmosphere. Close the valve of the balloon pump after the reading is 0.
3. Select [ Main Menu ]

5. Check the manometer values and the monitor values. Both should be 0mmHg.
6. Raise the pressure in the metal vessel to 50 mmHg with the balloon pump. Then, wait for 10 seconds until the
measured values become stable.
7. Compare the manometer values with the displayed values. The difference between the manometer and displayed
values should be within ± 3 mmHg.
8. Raise the pressure in the metal vessel to 200 mmHg with the balloon pump. Then, wait for 10 seconds until the
measured values become stable and repeat step 6.
If the difference between the manometer and displayed values is greater than 3 mmHg, contact your service personnel.
