Build a maintenance routine around manufacturer guidance, staff training and service support.
High-flow nasal cannula systems and respiratory humidifiers play a pivotal role in managing acute hypoxemic respiratory failure across intensive care and high-dependency units.
Routine maintenance and strict disinfection protocols prevent cross-contamination and prolong the working life of high-performance flow generators.
Establish a standardized daily inspection checklist for heated breathing circuits and water chambers to prevent airway condensation and sensor calibration drift.
Daily inspection and setup protocols
Before connecting a patient to heated high-flow respiratory therapy, ensure the chamber float mechanism operates smoothly and that sterile water feeds consistently without overfilling.
Heated wire breathing circuit maintenance
Heated breathing tubes prevent condensation rain-out while delivering conditioned gas at physiological body temperature:
- Inspect circuit silicone tubing for kinks, cracks, or electrical connector moisture.
- Verify temperature probe seating at both proximal chamber and patient airway ends.
- Ensure disinfection caps are fitted during decontamination cycles.
- Never autoclave single-patient disposable breathing circuits.
Flow and oxygen sensor calibration
Regularly verify oxygen percentage output against certified calibration analyzers. Clean or replace inlet air dust filters according to manufacturer hour thresholds.
Biomedical support and scheduled preventive maintenance
Schedule bi-annual preventive service reviews with authorized technicians to test blower motor turbine pressures and internal battery health.
