GE HealthCare · Model E-CAiOVX
Airway modules specifically designed for Anesthesia Monitor and Compact Anesthesia Monitor to measure anesthetic agent with identification, CO2, Patient Oxygen™, Patient Spirometry™ and direct gas exchange. All parameters measured at the patient’s airway D-fend™ water separation system Patient Oxygen – Datex-Ohmeda paramagnetic technology – Inspired and end-tidal values, inspired/expired difference, waveform CO2 and N2O – Datex-Ohmeda infrared technology – Inspired and end-tidal values, waveform and respiration rate Anesthetic agents – Datex-Ohmeda infrared technology – Measures and identifies all five agents: Halothane, Enflurane, Isoflurane, Sevoflurane and Desflurane – MAC (Minimum Alveolar Concentration) – Agent mixture detection Balance gas Patient Spirometry – Datex-Ohmeda patented D-lite+™ and Pedi-lite+™ flow sensor and gas sampler – Airway pressures, waveform, minute and tidal volumes, compliance, airway resistance and flow waveforms – Pressure-volume and flow-volume loops – Ability to store and print up to six loops – Recall saved loops to compare to current loop Gas Exchange – Direct and continuous measurement – Oxygen consumption (VO2) and carbon dioxide production (VCO2). – Values for energy expenditure (EE) and respiratory quotient (RQ). Full numerical and graphical trends of all measured data
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
Failure patterns typical of this equipment class - general BMET reference, not verified against this exact unit's own service history unless flagged. Severity is a category-level estimate.
Vaporizer calibration drift
HighSymptoms: Delivered agent concentration off, low/high agent alarm.
Root cause: Worn bellows or O-ring; agent contamination.
O2 failure / pipeline alarm
HighSymptoms: O2 low-pressure alarm, inability to ventilate.
Root cause: Pipeline disconnect or failed O2 flush valve.
Breathing circuit leak
HighSymptoms: Low minute volume, volume loss, leak alarm.
Root cause: Loose connections, torn bellows, cracked hose.
Absorber exhaustion
MediumSymptoms: Rising EtCO2, patient rebreathing.
Root cause: CO2 absorbent saturated.

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 structured starting point derived from the failure modes above. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Vaporizer calibration drift
- Confirm the presentation - typically delivered agent concentration off, low/high agent alarm - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: worn bellows or O-ring; agent contamination.
- Isolate the affected subsystem using the manufacturer's functional check or self-test, where one is provided.
- If the fault is confirmed and not a field adjustment, service or replace the vaporizer (agent-specific) per the manufacturer's service documentation.
- Return the device to service only after the manufacturer's functional and applicable electrical-safety checks pass.
- Record the findings, any parts used, and the verification results in the maintenance history.
