GE HealthCare 8000
GE HealthCare · Model 8000
Key Features Integrated internal anesthetic gas scavenging system Compatible with O and NO delivery systems Supports multiple ventilator options, including: Ohio V-5 Ohio V-5A Ohmeda 7000 Ohmeda 7800 Compatible with TEC IV, TEC V, and TEC VI vaporizers Selectatec® SM mounting system supports and interlocks up to 3 vaporizers for added safety and flexibility.
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.
Fails the pre-use leak / machine check
HighSymptoms: Low-pressure or circle-system leak test fails, machine not ready for use.
Root cause: Breathing-circuit / absorber leak, a worn APL valve or bag arm, a CO2-absorber canister seal, or a vaporiser back-bar leak.
Ventilator / bellows or piston fault
HighSymptoms: Set tidal volume not delivered, bellows will not fill or hangs up, piston fault, PEEP not held.
Root cause: Bellows leak, a drive-gas valve fault, a flow-sensor fault, or a piston-seal fault.
O2 flowmeter / hypoxic-guard fault
MediumSymptoms: O2 flow not matching the setting, flowmeter float sticking, hypoxic-guard / ratio fault, no O2 flush.
Root cause: Worn flowmeter (rotameter), a hypoxic-guard link fault, or a flush-valve fault.
Vaporiser fault
MediumSymptoms: Agent output does not match the dial, back-bar leak, dial stiff.
Root cause: Vaporiser seating / O-ring, or an internal vaporiser fault (calibrate at an authorised centre).
Gas-supply / pipeline / O2-failure alarm
MediumSymptoms: O2-failure whistle / alarm, anti-hypoxia device cuts N2O, pipeline-pressure fault.
Root cause: Loss of pipeline / cylinder pressure, or a pressure-sensor fault.
Scavenging (AGSS) fault
LowSymptoms: Waste-gas scavenging alarm or not evacuating, theatre pollution.
Root cause: Scavenging flow / connection or a receiver-valve fault.

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: Leak / machine check fails
- Run the check with the exact circuit and absorber.
- Reseat the CO2-absorber canister and check its seal; replace exhausted absorbent.
- Inspect the breathing-system gaskets, bag arm and APL valve.
- Check each vaporiser is seated with an intact O-ring.
- Re-run the check; escalate an internal leak that cannot be localised.
Symptom: Ventilator not delivering set volume
- Verify tidal volume with a calibrated gas-flow analyser.
- Inspect the bellows / piston and its seal for leaks.
- Calibrate the flow sensors.
- Check the drive-gas valve and circuit compliance compensation.
- Replace the bellows / flow sensors as isolated and re-verify.

Safety & Recalls
Synced live from the FDA openFDA API.
- RECALL
Loss of image data: Software anomaly in the Processing Software on the Definium 8000 system may impact patient safety when using the VolumeRAD advanced application (option). The slice visualization of VolumeRAD exams acquired on the Wallstand receptor will be offset by 17mm. This prevents the visualization of anatomy WITHIN a distance of 17mm from the wallstand patient barrier (receptor cover).
- RECALL
Radiation dose reading greater than actual dose: Error in the generator software on the GE Healthcare Revolution XR/d configured with HP 8200 PC consoles and all Definium 8000 systems may impact patient safety. Occasional generator software errors may cause light X-ray Images with reported mAs readings higher than was actually exposed to the patient using the overhead X-ray tube. The mAs rea

Necessary certification labels are missing from the x-ray contol.
