Make sure that the one-way valves (breathing circuit module) work
correctly.

• The inspiratory check valve rises during inspiration and falls at the start

of expiration.

• The expiratory check valve rises during expiration and fall at the start of

inspiration.

Note: The Bain/Mapleson D circuit module does not have one-way valves.

NIIIIN

Objects in the breathing system can stop gas flow to the patient.

This can cause injury or death:

• On Circle systems, press the drain button for a minimum of 10

seconds to remove moisture buildup.

• Do not use a test plug that is small enough to fall into the

breathing system.

NIIIIN

Make sure that there are no test plugs or other objects caught in the

breathing system.

Test the ventilator circuit for leaks:

•Set the Bag/Vent switch to Vent.

•Set all flow controls to minimum.

•Set the system switch to Standby.

•Close the breathing circuit at the patient connection. Use your hand or

an approved test plug located in the handle of the breathing system.

•Push flush to fill the bellows.

•The pressure must not increase to more than 15 cmH

O on the gauge.

•If the bellows falls more than 100 mL/min, it has a leak. Refer to the

troubleshooting procedure in the Setup, Maintenance and
Troubleshooting manual.

•Turn on the system.

Test the Bag circuit for leaks:

•Set the Bag/Vent switch to Bag.

•Close the APL valve.

•Set the O

flow to 250 mL/min.

•Close the patient connection (hand or test plug) and inflate the bag

(flush) to 30 cmH
