Step1: Check to make sure bag/vent switch is set correctly.
• If switch is set to manual mode continue with the next step.
• If set to ventilator mode fail with, "Wrong circuit selected".
Step2: Is O available and working?
2
• If O Supply is Not low and mixer passes a mixer flow test of 250 ml/min of
2
O continue with the next step.
2
• If not fail with "Low O
Step3: Is circuit (airway) pressure too high?
• Check the circuit (airway) pressure is less than 30 cm H
next step.
• If airway pressure greater than 30 cm H
• Step4: Find manual circuit leak:
• Increase flow to find the manual circuit leak.
• If pressure does not increase to 30 cm H

• If flow required to maintain pressure at 30 cm H
state "Manual circuit leak is XXX ml/min at 30 cm H
• If flow required to maintain pressure at 30 cm H
250 cm H 0 continue with the next step.

Step 5: Run mixer tests on the O
test):
• If O pressure is low, fail with "Low O
2
• If mixer does not fail the 3L,10L and the leak test, continue with the next step.
• If mixer fails the 3L,10L or the leak test, fail with the mixer failure.
Step 6: Run mixer tests on the Air channel (check supply and run a 3L, 10L and leak
test):
• If O is drive gas and air supply is low, continue with next step and indicate,
2
"Could not test air".
• If Air is the drive gas and air supply is low, continue with next step and
indicate, "Ventilator has not drive gas".
• If mixer does not fail the 3L,10L and the leak test, continue with the next step.
If mixer fails the 3L,10L or the leak test, fail with the mixer failure.
