Occlusion Test; Occlusion Test (Optional) - CareFusion Alaris GP Technical & Service Manual

Occlusion Test

This test can be only done as part of the PVP Work Flow.
Use the Infusion Set ten times only and then replace. Record how many times the Infusion Set has been used.
Note: The Occlusion Pressure Test is carried out with fluid in the Infusion Set.
This test is used to confirm that the pressure sensor is correctly calibrated and able to detect an occlusion at the correct line pressure.
This is done by pumping into a calibrated pressure gauge and checking that an alarm occurs at the correct line pressure. The test set-up
is as per figure 3 - 1.
1. Put the fluid filled Infusion Set (60793) into the Pump.
2. Enter the PVP Work Flow and proceed to the Occlusion Pressure Test.
3. Open the 3-way tap to atmosphere then press the
4. Configure the Calibrated Pressure Gauge to hold the Peak/MAX Pressure reading, in preparation for the test.
5. Press the START softkey to begin running the Pump at a rate of 125ml/h. Allow the Pump to run for 1 minute, so that the pressure
reading stabilises.
6. Turn the tap to occlude the Infusion Set into the pressure gauge.
7. The Pump will continue to infuse and it will be observed that the pressure reading increases. Eventually a high-pressure alarm will
occur and the Pump will stop infusing. Note the reading on the pressure gauge and confirm that it is 500mmHg ±100mmHg.
8. Press PASS softkey if Pump passes test at all levels.
If the pressure is outside of tolerance pressure calibration is required . Calibration should be performed as per
A
procedure in Chapter 2 'Configuration and Calibration' . If the pump continues to fail the occlusion test then the
pressure sensors should be replaced and perform the calibration procedure again .

Occlusion Test (Optional)

This test can be done in normal operating mode to check the occlusion without having to perform the full PVP Work Flow.
Use the Infusion Set ten times only and then replace. Record how many times the Infusion Set has been used.

2. Press the button to turn the pump on.
3. Open the 3-way tap to atmosphere.
4. Set the Rate to 125ml/h.
VTBI softkey and set VTBI to 10ml.
5. Press the
6. Press the e button and set the Pressure Alarm Limit to L5.
7. Configure the Calibrated Pressure Gauge to hold the Peak/MAX Pressure reading, in preparation for the test.
8. Press the b button to begin running the Pump at a rate of 125ml/h. Allow the Pump to run for 15 seconds, so that the pressure
reading stabilises.
9. Turn the tap to occlude the Infusion Set into the pressure gauge.
10. The Pump will continue to infuse and it will be observed that the pressure reading increases. Eventually a high-pressure alarm will
occur and the Pump will stop infusing. Note the reading on the pressure gauge and confirm that it is 500mmHg ±100mmHg.

12. Hold the button down for approximately three seconds to turn the pump off.
If the pressure is outside of tolerance pressure calibration is required . Calibration should be performed as per
A

pressure sensors should be replaced and perform the calibration procedure again .
LEVEL softkey to adjust the alarm level to L5.
