IMPACT 754 VENTILATOR: IN-FLIGHT EMERGENCIES
Missing or Damaged “GAS OUT” Leaf Valve
1. Missing “GAS OUT” leaf valve will trigger an alarm, give a DISCONNECT—CHECK
CIRCUIT CONNECTIONS” message, no “PEAK” value will display, and little to no volume
will be delivered to the patient.
a. Place the patient on BVM with supplemental O 2
b. Perform DOPE (Dislodgment, Obstruction, Pneumothorax, and Equipment) assessment.
c. Check the “GAS OUT” leaf valve for installation and proper seating.
i. If it’s folded, use a small object to unfold it or push the valve back into place gently.
ii. If missing, replace the ventilator immediately if able. If unable to replace, cover GAS
OUT side ports with an occlusive dressing. (Replacing the GAS OUT leaf valve is
optimal but time-consuming.)

WARNING: Occluding the GAS OUT side ports will enable the ventilator to provide full
respirations; however, this will eliminate the antiasphyxia function these ports provide.
Ventilator failure will result in increased resistance in spontaneous respiration, and
strict surveillance must be kept on the ventilator to ensure any further failure is caught
immediately. The patient must immediately be transitioned to BVM in the event of
any failure.
