Quick answer: Choose a CPAP mask by matching the prescribed PAP device and circuit, breathing route, pressure range, facial fit, leak, skin tolerance and the sleep clinician’s plan. A mask should seal comfortably without blocking its designed exhalation vent.
Main mask types
- Nasal pillows: rest at the nostrils and have minimal facial contact.
- Nasal mask: covers the nose.
- Oronasal or full-face mask: covers the nose and mouth.
The smallest-looking mask is not automatically best, and mouth breathing does not always require the same solution. Discuss persistent leak, nasal blockage or dry mouth with the sleep team.
Fit questions
- Is the mask compatible with the exact CPAP/APAP device and tubing?
- Was sizing checked in the patient’s usual sleeping position?
- Is leak acceptable at the prescribed pressure?
- Is the intentional vent open and unobstructed?
- Does the cushion cause persistent redness, pain or skin damage?
- Can the patient remove the mask independently if required?
Do not overtighten headgear to stop every leak. Excess tension can cause skin injury and may distort the cushion. Do not tape over exhalation vents or improvise non-approved connectors.
Cleaning and replacement
Use the manufacturer’s cleaning instructions for the exact mask, cushion, frame and headgear. Replacement timing depends on wear, damage, seal and hygiene; it should not be presented as one universal calendar. Replace cracked, stiff, torn or poorly sealing parts with compatible components.
When to contact the care team
Ask for review when leak remains high, treatment is repeatedly removed, pressure feels intolerable, symptoms persist or skin damage develops. Do not change prescribed pressure to compensate for a mask problem.
Before arranging a mask, identify the prescribed device through the CPAP and APAP models and confirm its compatible interface and fitting support; the mask is a separate patient-specific choice.
