Step 1: "Bag/Vent Switch" - Verify the Bag/Vent Switch is set correctly.
• If the switch is set to Ventilator Mode continue with next step
• If the switch is set to Manual Mode, fail with "Wrong circuit selected".
Step 2: "O2 Pressure" - Is O
• If O Supply is adequate and mixer passes a mixer flow test of 250 ml/min of

O continue with the next step.

• If not fail with "Low O2 supply pressure" or with mixer failure.
Step 3: "Ventilator Drive Pressure" - Make sure ventilator has drive gas pressure:
• If drive gas pressure (as measured by the Manifold Pressure Transducer)
continue with the next step.
• If no drive gas pressure, fail with "Ventilator has no drive gas".
• If all of the steps above pass, the ventilator will be commanded to flow
12 L/min (Software less than 3.20) or 18 L/min (Software equal to or greater
than 3.20). Before selecting "Continue" on the next menu, "Make sure the
bellows are fully collapsed" before you "Occlude the Patient Y".
Step 1: "Verify the Bellows Empty" - Check to make sure bellows is collapsed.
• If Airway pressure increases to or above 30 cm H
with, "Can not empty bellows".
• If not continue with next step.
Step 2: "Circuit Leak Test" - Attempt to find the leak of the ventilator mode system.
Leak < 250 ml
If the
• Flow 1 l/min O2 until pressure increases to 20 cm H
• If pressure does not increase to 20 cm H
"Cannot pressurize circuit". If it does reach 20 cm H
250 ml/min.
• If a flow of 250 ml/min reaches 30 cm H
less than 250 ml/min" and continue to next step. If it does not, increase flow
up to 750 ml/min.
• If a flow of 750 ml/min that reaches 30 cm H
indicate the "Ventilator circuit leak is between 250 ml/min and 750 ml/min".
• If the circuit pressure does not increase to 30 cm H2O with 750 ml/min flow,
fail with "Ventilator circuit leak is greater than 750 ml/min".
