GE HealthCare Universal PAC
GE HealthCare · Model Universal PAC
Carrying case.
Key tips
- ·A failed daily leak test takes the machine out of service immediately - there is no acceptable workaround.
- ·Never run an agent-specific vaporizer with the wrong agent, even briefly, during testing.
- ·CO2-absorbent exhaustion mimics several unrelated fault symptoms - rule it out early.
Typical Failure Modes
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Delivered agent concentration inaccurate
HighSymptoms: Agent analyser shows the output does not match the dial beyond the vaporiser's stated tolerance.
Root cause: The vaporiser is out of calibration - recalibration is done only at an authorised service centre.
Back-bar / mounting leak
MediumSymptoms: Machine leak test fails with this vaporiser fitted, agent smell.
Root cause: Worn back-bar O-rings / mounting seal, or the vaporiser not fully locked / Selectatec latched onto the manifold.
Filling / drain fault
MediumSymptoms: Will not fill (keyed or funnel filler), spills, or overfills; sight glass hard to read.
Root cause: Worn filler seal / valve, or the wrong agent bottle adapter.
Concentration-dial / interlock fault
MediumSymptoms: Dial stiff, will not turn past the 0 / T interlock, or does not stay at a setting; Selectatec interlock not releasing.
Root cause: Worn dial detent / interlock or an internal control-cone fault.
Tipped / contaminated with agent in the bypass
LowSymptoms: Grossly high output for a period after the vaporiser was tipped or moved.
Root cause: Agent carried into the bypass channel after tipping - purge at high flow before clinical use.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Daily pre-anesthesia machine check: leak test, O2 sensor calibration, per facility protocol
- ·Scheduled vaporizer calibration and agent-specific service
- ·Absorber / CO2 canister replacement
- ·Breathing circuit and hose inspection
- ·Annual full PM and electrical safety test
Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Concentration inaccurate
- Verify output with a calibrated agent analyser at ~5 L/min O2, 21 +/- 2 C, across the dial range.
- Confirm the correct agent is in the vaporiser.
- Rule out a back-bar leak (machine leak test).
- If output is out of spec, send the vaporiser to an authorised service centre for recalibration.
- Check the calibration certificate for the due date.
Symptom: Back-bar leak or fill fault
- Reseat and fully lock / latch the vaporiser on the manifold.
- Replace the back-bar O-rings / mounting seal.
- Repeat the anaesthesia machine leak test.
- Inspect the filler seal / valve and use the correct agent adapter.
- Purge at high flow if the vaporiser was tipped.

Safety & Recalls
Synced live from the FDA openFDA API.
- RECALL
Under certain workflows, patient information shown in the viewer may not match the images displayed on Centricity Universal Viewer Zero Footprint Client (ZFP) with versions ZFP v6.0: SP11.6, SP11.6.0.1 and SP11.6.1 on systems with Patient Timeline installed,
- RECALL
There is a potential security vulnerability in Centricity Universal Viewer (UV), Centricity PACS-IW (PACS-IW), Centricity Radiology RA600 (RA600), & Centricity Cardiology CA1000 (CA1000) where the service login credentials are able to be identified which could allow a malicious actor with these credentials to access the system and potentially manipulate patient data.
- RECALL
GE HealthCare has become aware of an issue in Centricity Universal Viewer Zero Footprint Client (ZFP) where there is a potential security vulnerability which could allow a malicious actor to access the system and potentially manipulate patient data.
- RECALL
GE HealthCare has become aware of an issue in Centricity Universal Viewer Zero Footprint Client (ZFP) version v6.0 SP11.x where the latest report is not shown by default to the user. The issue may occur when a study has multiple DICOM structured reports (i.e. preliminary, final, and/or addendum) stored in different series.
- RECALL
Footprint Client (ZFP) versions v6.0 SP9.x and SP10.x where the latest addended report is not shown by default to the user. The issue occurs when the addendum is created on the same day as the original report but at a different time, and only when launched on the following browsers. " Internet Explorer 10 (IE10) " Internet Explorer 11 (IE11) " Firefox.
- RECALL
When using Universal Viewer or Centricity Universal Viewer with Workflow Manager (WFM), if a third-party reporting application is used to launch exams, it could display information on a different patient than WFM and the Viewer.
- RECALL
GE HealthCare has become aware of an issue where information from two different patients can be mismatched when correcting patient or study information.
- RECALL
Inaccurate distance measurements with magnified projection X-ray images.
- RECALL
Images from the Centricity PACS-IW with Universal Viewer and Centricity Universal Viewer may be missing when a system parameter MapRoute is set to a value greater than 1.
