WARNING
Objects in the breathing system can stop gas flow to the patient. This can
cause injury or death:
• Do not use a test plug that is small enough to fall into the breathing
system.
• Make sure that there are no test plugs or other objects caught in the
breathing system.
1. Turn all flow control valves to their minimum setting.
2. Set the Bag/Vent switch to Vent.
3. Attach a patient circuit to the breathing system.
4. Occlude the patient port.
5. Remove the rear cover from the breathing system.
6. Remove the scavenging assembly and plug the scavenging port with a test
plug.
7. Push the flush button to fill the bellows. The inspiratory pressure gauge
should not exceed 60 cm H
2
O with the flush button pushed (will typically
be 50–55 cm H
2
O).
8. Release the flush button. Within 4 seconds, the absorber pressure gauge
should fall to between 20 and 40 cm H
2
O. After it reaches this pressure, it
may continue to fall but at a much slower rate.
9. Remove the test plug from the scavenging port.
