3.8 Vaporizer back pressure test
WARNING Anesthetic agent vapor comes out of the common gas
outlet during this test. Use a safe, approved procedure to
remove and collect the agent.
1. Set up the gas scavenging system.
• Attach a patient circuit and plug the patient port.
• Attach a bag to the bag port (or plug the bag port).
• Adjust the APL valve to minimum.
2. If equipped, set the ACGO selector switch to Breathing System.
3. Set the Bag/Vent switch to Bag.
4. Set the system switch to On.
5. Set the O
2
flow to 6 L/min.
6. Make sure that the O
2
flow stays constant and the float moves
freely.
7. Adjust the vaporizer concentration for each step from 0 to 1%.
The O
2
flow must not decrease more than 1 L/min through the full
range. If the O
2
flow decreases more than 1 L/min:
• Install a different vaporizer and try this step again.
•If the O
2
flow decreases less than 1 L/min with a different
vaporizer, the malfunction is in the first vaporizer.
•If the O
2
flow also decreases more than 1 L/min with a
different vaporizer, the malfunction is probably in the 9100c
system. Do not use the system until it is serviced (repair
vaporizer manifold port valve).
8. Complete steps 5 through 7 for each vaporizer and vaporizer
position.
9. Set the system switch to Standby.
10. Turn all of the flow controls fully clockwise (closed).
