High O2 Supply
(Failure/Fault)
Description:
O2 input pressure too
high
Possible Cause:
• O2 supply pressure
too high
• Faulty regulator
• Faulty O2 Pressure
Transducer
• Check O2 supply-> O2 supply pressure too high-
>Decrease O2 supply
• Check O2 regulator ->Faulty regulator -> Replace O2
regulator on O2 inlet
• Faulty SPM Module>Replace SPM Module
1051 Self Check Failure Description:
Run-Time Calibration
Failure
Possible Cause:
• Kinked hose
• Auto Cal valve
• Ventilator needs
calibration
• Faulty transducer
• Persistent high
vibration or
electrically noisy
environment
1. To Check for kinked tube or auto Cal valve
Does it occur at startup, or does it occur after running for
some time?
A. At startup implicates transducer or kinked CF/OF/
Auto Cal pathway hose->Correct hose
B. Runtime implicates auto Cal valve->Replace SPM
Module
To Check Valves
2. Run exhalation, backup and auto Cal valve check to make
sure valves are good-valve failure->replace SPM Module
3. To Check Calibration
4. If valves are good, run calibration checks for O2 flow,
compressor flow, and airway pressure to see if one is out
of spec->Calibration error->Calibrate
5. Rerun calibration for failing calibrations (if this works, it
means a transducer offset shifted since device was last
calibrated)->unable to calibrate->replace SPM Module
1052 Self Check Failure Description:
Airway pressure signal
is stuck high or stuck
low or is unchanging.
Possible Cause:
• Calibration drift
• Kinked tubing
• Bad airway pressure
transducer
• Contamination on
PCB near airway
pressure transducer
/ PGA
• Check calibration -> calibration drift ->recalibrate
• Check AW Pressure/Auto Cal pathway tubing ->kinked
tubing -> Correct tubing
• Bad airway pressure transducer -> Replace SPM module
• Check SPM PCB for contamination -> Replace SPM
module
