4. Check that a low pressure alarm is triggered.
5. Connect the Y-piece to the test lung.
6. Check that the low pressure alarm is cancelled.
5.12 Breathing System Test
1. Check that the non-return valves in the breathing system
work correctly:
a) The inspiratory non-return valve opens during
inspiration and closes at the start of expiration.
b) The expiratory non-return opens during expiration and

5. Deflate the bellows.
6. Connect the Y-piece to the absorber test block.
7. Press and hold the O2 flush button to fill the bellows.
8. The airway pressure gauge must indicates less than 15
cmH2O.
9. Release the O2 flush button.
10. If the bellows deflates within one minute,.
a) Remove the bellows and reinstall, refer to Section
7.3.7.
b) Repeat the bellows test.
Breathing system leak test
11. Set the Bag/Vent switch to the bag position.
12. Turn the APL valve to 50 cmH2O
13. Press the O2 flush button until the airway pressure gauge
reads 25 cmH2O.
14. Release the O2 flush button.
15. Make sure that the airway pressure gauge reading does
not reduce.
CAUTION
If a leak is suspected, check the bellows, breathing tube,
absorber, and connectors for correct function and security.
