Diamedica DPA-02
Diamedica · Model DPA-02
Supplied with one low resistance vaporiser, suitable for use with Isoflurane and Halothane or Sevoflurane The machine can be assembled in two minutes Weighing 10kg the DP02 is lightweight and easily carried as aircraft hand luggage Contained in a shockproof and waterproof Peli case it is suitable for use in the most remote locations in the world Compatible with Helix portable ventilators for mechanical ventilation Designed and engineered and manufactured in the UK, robust and built to last CE certified by an internationally recognized notified body
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.
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.
Scavenging system fault
MediumSymptoms: High scavenger pressure, agent smell in OR.
Root cause: Obstructed scavenger line or failed regulator.
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.
