Ventilator & Calibration Troubleshooting
906-0731-04-01 Rev. C ZOLL Ventilator Service Manual 6–17
Breath performance test failed due to setup issue and is now
saturated with O2.
• Purge patient circuit of O2 with the following
method:
• Power on device.
• Select mode button.
• Press Accept/Confirm button.
• Note:
The device will start ventilating, alarms may
occur.
• Allow the device to deliver several breaths, this
should flush any O2 out of the patient circuit.
• Power off device.
• Retry the Breath Performance Test.
The RCS is used to calibrate the device on an annual basis.
• The Incoming System Test confirms the device meets
specification (as defined in the operation manual).
• The Outgoing System Test confirms the device can
operate at a tighter tolerance to ensure the device
can maintain operational specifications for the PM
cycle.
Autocal Valve failures: Release 4 vs. Release 5.
Continues to monitors the autocal valve’s ability to manage the
transducer drift across environments.
• The RCS now confirms the valve is behaving as
expected at each annual PM. Expect reduced rate of
field failure.
Majority of pneumatic test issues are due to Set Up and Test Station
issues.
This calibration is based on the measurements of the reference
device (TSI).
• Check Set-Up
• test apparatus is not removed from the device before
the next test step.
• Check Test Station
• O2 Regulator
• TSI Connections
The TCE detects a corrupt calibration file and prompts:
Do you want to upload a default cal file?
• Respond to Prompt:
• Select: No
• Attempt to perform a calibration. Selecting “Yes” will
overwrite the SPM serial numbers and Write will
need to be done.
