Philips M1018A TCPO2/TCPCO2 Module
Philips Healthcare · Model M1018A TCPO2/TCPCO2 Module
Module Philips Transcutaneous Gas is designed for use in neonatal intensive care environments. Skin surface tcpO2/tcpCO2 measurements correlate with changes in arterial partial pressure of oxygen and carbon dioxide, offering a non-invasive means of continuous monitoring. Individual and trend data provided by transcutaneous gas monitoring are a significant complement to arterial blood gas measurements in monitoring neonates on ventilators.
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 / tcpO2 readings drift or need calibration
HighSymptoms: CO2, O2, agent or tcpO2/tcpCO2 values off vs a reference, calibration prompts.
Root cause: Sensor aging, a missed calibration, or the wrong calibration gas; (tcpO2) an old membrane / electrolyte.
Module not recognised by the host
MediumSymptoms: Host monitor (IntelliVue / MP series) does not display the module or MMS.
Root cause: Docking / rack 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: Gas / SpO2 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 / CO2 sensor (or the tcpO2 membrane / electrolyte).
- Let the module warm up fully.
- Verify against a reference gas mix.
Symptom: Module not recognised
- Reseat the module / MMS 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 host slot as isolated.
