Key Features Integrated hemodynamic and airway gas monitor designed for operating rooms and recovery areas Intuitive Datex-Ohmeda user interface with anesthesia-specific menu navigation and alarm management Compact, space-saving design for environments where space is limited Large numeric values and waveforms for excellent visibility from a distance Built-in backup battery for uninterrupted operation during unexpected power loss Integrated mounting system supports quick installation on optional wall mounts, roll stands, and anesthesia machine mounting arms.
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.
Gas / agent readings drift or need calibration
HighSymptoms: CO2, O2, N2O or agent values off vs a reference, calibration prompts, agent ID wrong.
Root cause: Gas-bench aging or a missed calibration, or contamination in the sampling path.
Water trap (D-fend) / sampling-line occlusion
MediumSymptoms: Occlusion or sample-flow alarm, no or low sample flow, flat gas waveforms.
Root cause: Full or expired D-fend water trap, a blocked / kinked sampling line, or a blocked occlusion filter.
Sample pump wear
MediumSymptoms: Slow gas response, low sample flow that a new trap and line do not fix.
Root cause: Worn internal sample pump.
A parameter (ECG / SpO2 / NIBP / temp) drops out or reads wrong
MediumSymptoms: Noisy or absent trace, no reading, NIBP times out.
Root cause: Worn patient cable / sensor, or a monitor input 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.

Enter the appropriate service menu(s) and check/verify the correct operation of the pump, valves, etc.
Sudden increase in gas displayWater trap malfunction. Check all internal tubing and the interior of the water trap for occlusions or leaks.
Replace water trap. Check flow rates.
Significant drift in all gasesLeak in sampling line or internal tubing (especially in conjunction with readings that are too low).
Check/correct leak in sampling line or internal tubing.
ETCO2 value too lowLeak in sampling system. Calibration error. High ventilator by-pass flow. Possible clinical causes: sudden circulation decrease, pulmonary embolism, very large dead-space, hyperventilation, or large shunting.
Check all connections. Check calibration.
ETCO2 too highD-fend contaminated. Calibration error. Possible clinical causes: hypoventilation or increased metabolism.
Change D-fend. Check calibration.

Change scale
ETCO2>PaCO2"Dry gas" is default. Possible clinical cause: unit is mmHg or kPa and ETCO2 is close to arterial PCO2.
Change to "wet gas" by using install/service menu.

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 readings drift / occlusion alarm
- Fit a fresh D-fend water trap and a Datex-Ohmeda sampling line.
- At PM, replace the occlusion filter, zero absorber, Nafion tubing and OM reference filter.
- Run the gas calibration with the correct calibration gas.
- Confirm the sample pump reaches the specified flow.
- Calibrate or replace the O2 sensor.
Symptom: A parameter drops out / NIBP problem
- Reseat the patient cable and check the site / sensor.
- Swap in a known-good cable for that parameter.
- Leak-test the NIBP cuff and hose.
- Run the monitor's NIBP calibration verification.
- Refer the monitor for internal pump / valve or input-board service if it persists.
