Breathing system tests
1. Make sure that the auxiliary equipment is functioning correctly.

indicator on the side. Make sure that the flow indicator shows
a flow in the green range.
3. Make sure that the check valves on the breathing circuit module
work correctly.
•
The expiratory check valve rises during expiration and falls at
the start of inspiration.
• The inspiratory check valve rises during inspiration and falls
at the start of expiration.
WARNING Objects in the breathing system can stop gas flow to the
patient, causing injury or death. Use a test plug that is the
appropriate size so that it will not fall into the breathing
system.
After performing the breathing system tests, make sure
that there are no test plugs or other objects caught in the
breathing system.
