NIBP Accuracy Test
Tool required:
T-shape connector
Appropriate tubing
Balloon pump
Rigid Vessel with 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 equipments as shown below.
2. Before inflation, check that the reading of the manometer is 0. If not, turn off the
balloon pump to let the whole airway open to the atmosphere. Turn on the balloon
pump after the reading is 0.
3. Select [Main

][NIBP Accuracy Test].
4. Check the manometer values and the monitor values. Both should be 0 mmHg.
5. Raise the pressure in the rigid vessel to 50 mmHg with the balloon pump. Then, wait for
10 seconds to let the measured values become stable.
6. Compare the manometer values with the monitor values. The difference between the
manometer and displayed values should be ± 3 mmHg. If it is greater than ± 3 mmHg,
calibrate the monitor as described in .
7. Raise the pressure in the rigid vessel to 200 mmHg with the balloon pump. Then, wait
for 10 seconds to let the measured values become stable. Repeat step 6.
NOTE
You can use an NIBP simulator to replace the balloon pump and the reference
manometer to perform the test.
You can use an appropriate cylinder and a cuff instead of the rigid vessel.
