3.9 Low-pressure leak test
Note Perform either the “Negative low-pressure leak test” or the “ISO or
BSI standard low-pressure leak test.” It is not necessary to perform
both tests.
WARNING Do not use a system with a low-pressure leak. Anesthetic
gas will go into the atmosphere, before reaching the
breathing circuit.
3.9.1 Negative low-
pressure leak test
With ACGO 1. Test the leak test device:
• Put your hand on the inlet of the leak test device. Push hard
for a good seal.
• Squeeze the bulb to remove all air from the bulb.
• If the bulb completely inflates in less than 60 seconds,
replace the leak test device.
2. Turn off all vaporizers.
3. Test the anesthesia machine for low-pressure leaks:
• Set the ACGO selector switch to ACGO.
• Turn all flow controls fully clockwise (zero flow). Do not
overtighten.
• Connect the leak test device to the ACGO outlet.
• Compress and release the bulb until it is empty.
• The vacuum causes the floats to move. This is usual. If the
bulb completely inflates in 30 seconds or less, there is a leak
in the lowpressure circuit.
4. Test each vaporizer for low-pressure leaks:
• Set the vaporizer to 1%.
• Repeat step 3.
• Set the vaporizer to OFF.
• Test the remaining vaporizers.
5. Disconnect the test device.
WARNING Agent mixtures from the low-pressure leak test stay in the
system. Always flush the system with O
2
after the low-
pressure leak test (1 L/min for one minute).
Turn off all vaporizers at the end of the low-pressure leak
test.
6. Flush the system with O
2
