CPAP Setup: Role of Respiratory Therapists & Patient Self-Management

Continuous Positive Airway Pressure (CPAP) therapy requires proper initial setup for efficacy and adherence.

Respiratory Therapist (RT) Role (Gold Standard)

• Mask fitting (nasal, nasal pillows, full face) – leak <24 L/min.
• Pressure titration (if auto-CPAP, set range; if fixed, confirm prescribed cmH₂O).
• Humidification settings (heated tube, humidity level).
• Data download / telemonitoring setup.
• Patient education: Cleaning, troubleshooting, adherence expectations.
• Follow-up at 2 weeks, 30 days, 90 days (adherence >4 hrs/night, 70% nights).

When Self-Setup Occurs

• DME ships device directly (insurance requirement, rural access).
• Manufacturer videos / app-guided setup.
• Telehealth RT session (increasingly common post-COVID).

Patient Self-Setup Checklist

1. Unbox; verify model, serial #, prescription pressure.
2. Assemble: Humidifier chamber → fill distilled water → connect tubing → mask.
3. Fit mask: Straps snug but not tight; no leak at bridge/cheeks.
4. Turn on; ramp feature (gradual pressure rise) for comfort.
5. Sleep; next morning check data (AHI, leak, usage hrs) via app/SD card.
6. Adjust: Mask type/size, humidity, ramp, EPR/Flex (expiratory pressure relief).

Red Flags for Professional Help

• Persistent leak >24 L/min or mouth leak.
• Intolerable pressure (aerophagia, claustrophobia).
• AHI >5 after 30 days optimal use.
• Skin breakdown, conjunctivitis, nasal trauma.

RT involvement improves adherence 15–20%; advocate for RT access if self-setup fails.
