SCAVENGING SYSTEM
*8. Adjust and Check the Scavenging System
- Ensure proper connections between the scavenging system and both the adjustable
pressure limiting (APL) (pop-off) valve and the ventilator's relief valve.
- Adjust the waste gas vacuum (if possible).
- Fully open the APL valve and occlude the Y-piece.
- With minimum O2
flow, allow the scavenger reservoir bag to collapse
completely, and verify that the absorber pressure gauge reads about zero.
- With the O2
flush activated, allow the scavenger reservoir bag
to distend fully, and then verify that absorber pressure gauge reads <10 cm H2
O.
