6.5 Pre-Use Check
Before use carry out the following.
1. Check that the vaporizer(s) for the required volatile agent(s)
are fitted correctly to the anaesthetic machine, that any
backbar locking mechanism is fully engaged and that the
control knob(s) rotate through their full range(s). Turn off the
vaporizer(s).
2. Check that the flow through any vaporizer is in the correct
direction.
3. When charging each vaporizer ensure that the correct
anaesthetic agent is used, and that the filling port is left
tightly closed.
4. Where the anaesthetic machine is fitted with a pressure relief
valve the following tests should be performed. (There may
be a dangerous increase in pressure if these tests are
performed in the absence of such a valve.)
(i) Set a suitable test flow of oxygen (6-8 litre/min), and, with
the vaporizer in the "off" position, temporarily occlude the
common gas outlet. There should be no leak from any of the
vaporizer fitments, and the flowmeter bobbin will dip.
(ii) Repeat this test with each vaporizer in the "on" position.
There should be no leak of liquid from the filling port.
Turn off the vaporizer(s), and the oxygen flowmeter control valve.
