IMPACT 754 VENTILATOR:
PRE-MISSION CHECKS AND TROUBLESHOOTING
Power On Checks
1. Turn the "MODE" knob (1) to the desired setting (A/C, SIMV, CPAP)

2. The ventilator will run a SELF-TEST upon setup. CAUTION: SELF CHECK must be
performed with the disposable ventilator circuit disconnected.
**Ignoring this requirement could cause the SELF-CHECK process to sense a residual
airway pressure, leading to a SELF CHECK failure.**
At this point, CAL is not required. If SELF-TEST results in a Calibration Failure, place (1) to
CAL until CAL OK is displayed. If calibration fails, the ventilator is deadlined.
