5. Mount and lock the vaporizer onto the vaporizer mount. (The vaporizer must be set to at
least 1%.)
6. Set the fresh gas flow to 0.2 L/min.
7. Adjust the APL valve to 70 cmH2O.
8. Push the O2 flush button until the airway pressure gauge value increases to about 30
cmH2O.
9. Release the flush button. Verify that there is no pressure decrease on the airway pressure
gauge.
10. Turn off the vaporizer.
11. Repeat steps 5 to 10 for the other vaporizer.
5.9 Other Functional Tests
5.9.1 High-Flow O2 Supply Test
1. Provide O2 and air supply for the anesthesia machine.
2. Press the high-flow O2 supply button to enable high-flow O2 supply.
3. Verify that the initial flow is 0, the initial O2 concentration is 100%, and the glass tube float
is at the bottom.
4. Verify that the flow can be adjusted to a maximum of 60 L/min and the flow indication of
the glass tube is about 60 L/min (with a deviation not exceeding 10 L/min).
5. Adjust the O2 concentration to 21%. Verify that the flow can be adjusted to a maximum of
60 L/min and the flow indication of the glass tube is about 60 L/min (with a deviation not
exceeding 10 L/min).
6. Press and hold the high-flow O2 supply switch for a few seconds and then release it. Verify
that high-flow O2 supply is disabled and the glass tube float is at the bottom.
5.9.2 High-Pressure O2 Output Test
1. When O2 is supplied at the O2 inlet, press the high-pressure O2 output check valve with
your finger and verify that there is high-pressure gas output.
