25.5.2 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 higher 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][Maintenance >>]ė[User Maintenance >>]. Enter the required
password and then select [OK].
4. Select [Module Maintenance >>][NIBP Accuracy Test].
5. Check the manometer values and the monitor values. Both should be 0mmHg.
6. Raise the pressure in the rigid 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 monitor values. The difference should be 3
mmHg. If it is greater than 3 mmHg, contact your service personnel.
8. Raise the pressure in the rigid vessel to 200 mmHg with the balloon pump. Then, wait
for 10 seconds until the measured values become stable and repeat step 6.
