7.2.11 Inlet Leak
To test the inlet leak:
1. Set the ventilator to STS settings.
2. Connect the ventilator to a test lung using a patient circuit.
3. Verify that the three screws securing the filter cover are tight, to insure that air
leakage is prevented.
4. Connect a vacuum meter to the air inlet.
5. Activate ventilation.
The vacuum reading should be at least -0.16 (negative 0.16) Bar at the end of
expirium.
During expiration, a decrease in the vacuum meter’s negative pressure is
normal.
If the test fails:
1. Tighten the screws locking the filter cover.
2. Replace the filter.
3. Remove the filter cover and check the O-ring.
4. Check the Inlet-to-muffler connection for a leak.
