Vaporizer back pressure test
WARNING Anesthetic agent comes out of the common gas outlet
during this test. Use a safe, approved procedure to
remove and collect the agent.
CAUTION To prevent damage to the vaporizer, turn the flow controls
fully clockwise (minimum flow or off) before turning on the
system.
1. Set the System switch to On. Alarms may occur.
2. Set the O2 flow to 6 l/min.
3. Make sure that the O2 flow stays constant and the float moves
freely.
4. Adjust the vaporizer concentration from 0 to 1%. The O2 flow
must not decrease more than 1 l/min through the full range.
•
If the O2 flow decreases more than 1 l/min, install a different
vaporizer and repeat the steps 1 through 4.
• If the O2 flow decreases less than 1 l/min when testing a
different vaporizer, the malfunction is in the vaporizer that
failed the test.
• If the O2 flow decreases more than 1 l/min with the different
vaporizer, the malfunction is most likely in the system. Do not
use the system.
5. Repeat steps 1 through 4 for each vaporizer.
