Accuracy • The system warms fluids automatically to 40 ± 2°C and has redundant sensors to ensure fluid temperature accuracy. • The lightweight warmer (9.5 oz) can be placed close to the patient -- allowing less opportunity for fluid-cooling in the IV line. • It has a low priming volume (4mL), which reduces waste and improves control over fluid composition. • The warmer incorporates a layer that transfers heat effectively and prevents hot spots Mobility • When it’s time to move, the cartridge and the IV set are removed from the warming unit only to be reinserted into a warmer in the next area. • The warming unit and power source are highly durable and have been shock and vibration tested. • The cartridge may stay in-line to protect the IV set from potential infection -- whether fluid is being warmed or not. • The enFlow cartridge can be used for 24 hours of continuous patient warming. Speed • It warms fluids rapidly (18 s or less) to a temperature of 40 °C, so there’s no time spent waiting to warm (other warmers can take over 10 min). • The cartridge attaches in-line to standard IV sets at the start of procedures, so there’s no additional set-up or tubing requirements. • It offers one-button operation. It's intuitive and relatively easy to operate, simply turn on the power and be warming within seconds. • It requires little preventive maintenance (five year schedule) and no calibrations.
Key tips
- ·Never skip temperature-accuracy verification to save time - it's the one check that directly prevents burns.
- ·Hose/blanket connector wear is the most common real fault and the easiest to miss on a quick visual check.
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.
Heating element / cartridge fault
HighSymptoms: No heat, or overheat alarm.
Root cause: Heater element or thermal cutoff failure.
Temperature sensor drift
MediumSymptoms: Delivered fluid temperature out of set range.
Root cause: Inline/probe sensor aging or miscalibration.
Air-in-line detector fault
HighSymptoms: False or missed air-in-line alerts.
Root cause: Air detector sensor drift or dirty optics.
Disposable tubing set leak / seating fault
MediumSymptoms: Fluid leak, or won't prime.
Root cause: Worn cassette/tubing seat or cracked fitting.

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.
- ·Hose / blanket connector inspection
- ·Temperature-accuracy verification
- ·Annual 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: Heating element / cartridge fault
- Confirm the presentation - typically no heat, or overheat alarm - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: heater element or thermal cutoff failure.
- 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 heating element / plate 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.
