Datex Ohmeda M-OSAT S/5 Oxygen Saturation Module
Datex Ohmeda · Model M-OSAT S/5 Oxygen Saturation Module
TruTrak+ is a powerful proprietary SpO2 enhancement technique that incorporates high speed data sampling, motion identification and quantification, and motion correction to directly track the patient’s saturation during conditions of clinical motion. Diagnostic plethysmographic waveform. Compatible with Datex-Ohmeda OxyTip®+ Sensors and Cables. Wide variety of SpO2 sensors for different applications. Adjustable pulse beep volume.
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.
Gas / SpO2 readings drift or need calibration
HighSymptoms: Agent, CO2, N2O, O2 or SpO2 values off vs a reference, calibration prompts.
Root cause: Sensor aging, a missed calibration, or the wrong calibration gas.
Module / pod not recognised by the host
MediumSymptoms: Host monitor does not display the module or pod.
Root cause: Docking / pod connector or cable fault.
Water trap full / sample-line occlusion
MediumSymptoms: Occlusion or water-trap alarm, no or low sample flow, flat waveforms.
Root cause: Full or expired water trap, or a blocked / kinked sample line.
Cable / connector wear
LowSymptoms: Intermittent signal with cable movement.
Root cause: Worn patient cable.

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: Readings drift
- Fit a fresh water trap and sample line.
- Run the module's calibration with the correct calibration gas.
- Calibrate or replace the O2 sensor.
- Let the module warm up fully.
- Verify against a reference gas mix.
Symptom: Module / pod not recognised
- Reseat the module / pod at the host or rack.
- Inspect the docking connector for bent pins.
- Try it in another host or slot.
- Try a known-good module in this slot.
- Refer the module or the host slot as isolated.
