Vaporizer back pressure test
Anesthetic agent comes out of the circuit during this test.
Use a safe, approved procedure to collect and remove
the agent.
Agent mixtures from the vaporizer back pressure test
stay in the system. Always flush the system with O2 after
the vaporizer back pressure test (1 l/min for at least one
minute).
The vaporizer back pressure test is performed to check the proper
function of the vaporizer actuator pins that activate the Selectatec
™
manifold port valves. Perform this test every time a vaporizer is
attached to the system.
1. Start a case.
2. Set the O2 flow to 6 l/min.
3. Slowly adjust the vaporizer concentration from 0 to 1%.
• Make sure that the O2 flow stays constant.
• Verify that the system continues to operate without issuing
any related alarms.
4. Repeat this test for each vaporizer position.
5. Set the O2 flow to 1 l/min and continue flow for one minute to
flush out any residual agent.
