GE HealthCare Datex-Ohmeda AS/3
GE HealthCare · Model Datex-Ohmeda AS/3
The GE Datex-Ohmeda AS/3 Compact Anesthesia Gas Monitor includes 5 agent gas monitoring, non-invasive blood pressure, ECG, pulse oximetry, all cables, printer/recorder, and certification.
Key tips
- ·A no-signal/flatline alarm gets checked on the patient first, not the monitor - rule out a real clinical event before troubleshooting.
- ·Recalibrate NIBP against a reference manometer, not just a self-test pass.
- ·Reused patient cables (SpO2, ECG leads) are a common source of intermittent-fault complaints - swap the cable before the module.
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.
A parameter drops out or reads wrong
HighSymptoms: ECG, IBP, SpO2, temperature, CO2 or CO intermittently drops or is implausible.
Root cause: Worn patient cable / sensor, or a parameter-module / input-board fault.
NIBP will not measure or is inaccurate
MediumSymptoms: NIBP times out, cuff will not inflate / hold, readings implausible.
Root cause: Internal NIBP pump or valve, a cuff / hose leak, or a pressure-transducer fault.
Module / parameter not recognised
MediumSymptoms: The host does not display a plugged-in module or a built-in parameter.
Root cause: Docking / connector fault or an internal board fault.
Display / touchscreen fault
MediumSymptoms: Blank, dim or distorted display; unresponsive touchscreen.
Root cause: Display, backlight, or controller fault.
Battery / power fault
MediumSymptoms: Short battery run time, will not hold charge, will not power on.
Root cause: Aged battery pack or a power-supply fault.
Network / central-station connectivity fault
LowSymptoms: Monitor not shown at the central station, admit fails, intermittent drop.
Root cause: Wired / Wi-Fi network configuration or a communication board.

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.
- ·Routine cable and lead-wire inspection for fraying/wear
- ·Battery conditioning cycle
- ·NIBP calibration check against a reference manometer
- ·ECG / SpO2 accuracy verification against a patient simulator
- ·Annual 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: A parameter drops out
- Reseat the patient cable at the module / monitor.
- Swap in a known-good cable / sensor for that parameter.
- Dock the module on a different host / slot to isolate module vs host.
- Inspect the docking connector for bent pins.
- Replace the cable, or refer the module / input board if the fault stays with it.
Symptom: NIBP problem
- Leak-test the cuff and hose.
- Run the monitor's NIBP calibration verification.
- Check for a kinked hose or a positional patient limb.
- Verify NIBP against a reference / simulator.
- Refer the monitor for internal pump / valve service if it persists.

Safety & Recalls
Synced live from the FDA openFDA API.
- RECALL
A potential safety issue due to loss of gas monitoring associated with occlusion of specific D-Fend / D-Fend+ water traps used with Compact Airway Modules E/M-C(Ai)O(V)(X) and Cardiocap/5 monitors. This water trap occlusion could cause a loss of respiratory airway gas monitoring.
- RECALL
Unintended shut-down: The anesthesia machine may start shutting down without human intervention due to a faulty On/Standby Switch. Prior to shutdown, the system will issue an alarm and play a message that shutdown will occur in 8 seconds. The failure only affects the electrical portion of the switch. If the clinician does not intervene, the patient could experience hypoventilation leading to h

Issue 1 -Possible failure of CIC Pro audible alarms: Requests for telemetry defaults from Mobile Care Server could cause excessive CIC Pro memory consumption. This excessive memory consumption may lead to potential loss of audio at the CIC or a system reset or reboot.

There is a correction associated with Engstrom Carestation with an integrated Aerogen Professional Nebulizer System. There is an issue relating to the removal of the nebulizer cable from nebulizer connection port, which, when done while the nebulizer is active, may result in the discontinuance of mechanical ventilation. This issue affects all of the Engstrm Carestations shipped between 12/4/2006
- RECALL
Alarm sound-It is possible that the audible alarms from the speaker from the Datex-Ohmeda S/5 Anesthesia Delivery Unit (ADU) machine may dampen or disappear as a result of normal handling of the anesthesia machine. Visual alarms on the ADU are unaffected by this condition. The dampening or absence of audible alarms on the ADU may result in a delay in treatment.
