Teleflex Medical ConcahTherm Neptune
Teleflex Medical · Model ConcahTherm Neptune
Can be safely used across the continuum of care, from neonates to adults. Uses the safe, convenient ConchaColumn™ and prefilled sterile water reservoir system. Compatible with Hudson RCI® heated-wire breathing circuits. Adjustable temperature and temperature gradients to control circuit condensation. Designed for invasive and noninvasive applications, including noninvasive ventilation, Heated Humidified High Flow Nasal Cannula Therapy (HH-HFNCT) and Continuous Positive Airway Pressure (CPAP). Intuitive user interface. High ventilator output mode compensates for high outlet temperatures and challenging modes of ventilation. Displays and regulates to the desired patient airway temperature.
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.
Not producing humidity / temperature not reached
HighSymptoms: Dry gas to the patient, low airway temperature, chamber not warming.
Root cause: Heater base plate fault, chamber not seated, a temperature-probe fault, or a water-feed issue.
Heater-wire circuit alarm
MediumSymptoms: Rain-out in the tube, heater-wire fault alarm.
Root cause: Open heated breathing circuit or a heater-wire adapter fault.
Temperature probe fault
MediumSymptoms: Implausible temperature, probe-fault alarm, unit will not run.
Root cause: Damaged airway or chamber temperature probe or its connector.
Water chamber / auto-feed fault
MediumSymptoms: Chamber runs dry or overfills, water-out alarm.
Root cause: Float valve or auto-feed fault, or a cracked chamber.

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: Not reaching target humidity / temperature
- Confirm the chamber is fully seated and latched on the heater plate and has water.
- Check the airway and chamber temperature probes and connectors; swap in a known-good set.
- Confirm the heated breathing circuit is intact and the adapter is connected.
- Check the heater-wire circuit continuity.
- If it still will not heat, replace the heater base plate.
Symptom: Probe / heater-wire alarm
- Note the exact alarm.
- Try a known-good probe set.
- Inspect the heated circuit and adapter.
- Power-cycle the humidifier.
- Refer for service if the alarm persists.
