WARNING Objects in the breathing system can stop gas flow to the patient. This
can cause injury or death:
• Do not use a test plug that is small enough to fall into the breathing
system.
• Make sure that there are no test plugs or other objects caught in the
breathing system.
6.3.1 Test setup 1. Disassemble the breathing system to the point where you can remove the
exhalation valve (do not remove the exhalation valve on Aespire machine).
