• If O

flow decreases less than 1 L/min with a different vaporizer,
the malfunction is in the first vaporizer.
• If the O
2
flow also decreases more than 1 L/min with a different
vaporizer, the malfunction is in the anesthesia system. Do not use
the system until it is serviced.

WARNING Do not use a system with a low-pressure leak. Anesthetic gas will
go into the atmosphere, not into the breathing circuit.
Perform either the Negative low-pressure leak test or the ISO 5358 or BSI
standard positive low-pressure leak test. It is not necessary to perform both
types of tests.
