Ventilator & Calibration Troubleshooting
906-0731-04-01 Rev. C ZOLL Ventilator Service Manual 6–33
1060 Exhalation System
Failure
Description:
PEEP higher than
greater of PIP high limit
- 5 cmH2O or PEEP +
2.5 cmH2O for 3
consecutive breaths
Possible Cause:
• Kinked tubing
• debris/blockage in
exhalation drive or
exhaust port
• Blocked/occluded
exhalation valve
• Pinched patient
circuit line
• Faulty exhalation/
backup valve
(EX_CON_1,
EX_CON_2)
• Check AW Pressure/Auto Cal pathway for kinked tubing -
> Kinked tubing -> correct tubing
• Check drive and exhalation tubing ports -> debris/
blockage in exhalation drive or exhaust port -> correct
tubing / clean ports
• Check exhalation valve -> Blocked/occluded exhalation
valve ->replace patient circuit
• Check patient circuit ->Pinched patient circuit tubing -
>correct pinch
• Check exhalation/backup valve with RCS -> Faulty
exhalation/backup valve (EX_CON_1, EX_CON_2) ->
replace SPM Module
1061 Exhalation System
Failure
Description:
(Airway Pressure > 70
cmH2O for 1.5s) OR
(Airway Pressure >
greater of 35 cmH2O or
PIP High Limit for 5s)
Possible Cause:
• Blocked Exhalation
drive or exhaust
port
• Blocked exhalation
valve
• Kinked tubing
• Faulty airway
pressure transducer
• Check Exhalation Drive or Exhaust tubing ports ->
Blocked Exhalation drive or exhaust tubing/port -
>Correct blockage
• Check patient circuit exhalation valve -> Blocked
exhalation valve ->Replace exhalation valve patient
circuit
• Check AW Pressure/Auto Cal pathway for kinked tubing -
> Kinked tubing -> Correct tubing
• Faulty airway pressure transducer -> Replace SPM
Module
2062 Exhalation System
Fault
Description:
PEEP measured > PEEP
setting + 5 cmH2O
Possible Cause:
• Blocked Exhalation
drive or exhaust
port
• Blocked exhalation
valve
• Kinked tubing
• Faulty SPM Module
• Check Exhalation Drive or Exhaust tubing/ports ->
Blocked Exhalation drive or exhaust tubing/port -
>Correct blockage
• Check patient circuit exhalation valve -> Blocked
exhalation valve ->Replace exhalation valve patient
circuit
• Check AW/ Pressure/Auto Cal pathway for kinked tubing
-> Kinked tubing -> Correct tubing
• None of the above -> Faulty SPM Module -> Replace
SPM Module
3110 RTC Battery Low Description:
RTC alarm at start up,
date and time returned
to default
Possible Cause:
• RTC battery is
drained
• RTC battery contact
is intermittent
• Check RTC Battery -> RTC battery is drained -> Replace
RTC battery
• Check RTC Battery Contact -> Retention battery holder
clip -> RTC battery contact is intermittent -> Replace
