A BiPAP machine delivers a higher pressure during inhalation and a lower pressure during exhalation. The mask provides the interface through which that prescribed airflow reaches the patient.

If the mask does not seal properly, air can escape around the cushion or through the mouth when a nasal-only interface is used. Leaks can contribute to dry mouth, noise, disturbed sleep and reduced therapy effectiveness.

A nasal mask uses a shaped cushion that fits around the nose. It leaves the mouth free and provides a middle ground between a minimal-contact interface and a full-face design.

What should you watch for?

If your mouth opens during sleep, air may escape through it. A dry mouth or sore throat can be a sign worth discussing with your provider. Nasal congestion and cushion fit can also affect comfort.

Explore our Philips DreamWear Nasal Mask product page for an example of a nasal-style interface. Confirm current availability and compatibility before ordering.

A traditional full-face mask seals around both the nose and mouth. It can be useful when a person breathes through the mouth during sleep, has persistent nasal obstruction or needs an alternative to a nasal-only interface.

Full-face masks are sometimes used in respiratory care for patients with COPD, but mask choice must be based on the individual clinical situation and prescribed ventilation requirements.

Nasal pillow masks use small cushions or prongs positioned at the entrance of the nostrils. Their low-profile construction leaves most of the face uncovered and avoids placing a cushion across the nose bridge.

Do not choose or reject a nasal pillow mask based only on a pressure number. Ask your clinician or trained equipment provider whether the particular mask is suitable for your machine, settings and comfort needs.

1. Understand your breathing pattern

   Tell your provider if you mainly breathe through your nose, regularly breathe through your mouth or have persistent congestion.

2. Review your prescribed settings

   The mask must be appropriate for your machine and prescribed therapy. Never change pressure settings yourself to accommodate a mask.

3. Consider your sleeping position

   Side sleepers may prefer a low-profile design, but the seal, headgear and hose arrangement also affect stability.

4. Check face shape and skin sensitivity

   Facial hair, nose shape, sensitive skin and cushion placement can influence both fit and comfort.

5. Arrange a proper fitting

   When possible, compare suitable sizes and designs with a trained equipment provider before purchasing.

There is no universal winner between nasal, full-face and nasal pillow masks. The most suitable interface is one that fits correctly, is tolerable to wear and is appropriate for your prescribed treatment. If your mask causes persistent discomfort or leaks, ask your clinician or trained fitter to review the size, fit and alternatives.
