2. Positive airway pressure - Wikipedia

   en.wikipedia.org/wiki/Positive_airway_pressure

   Some full-face masks "float" on the face like a hover-craft, with thin, soft, flexible "curtains" ensuring less skin abrasion, and the possibility of coughing and yawning. Some people may find wearing a CPAP mask uncomfortable or constricting: eyeglass wearers and bearded men may prefer the nasal-pillow type of mask.

3. Continuous positive airway pressure - Wikipedia

   en.wikipedia.org/wiki/Continuous_positive_airway...

   Continuous positive airway pressure (CPAP) is a form of positive airway pressure (PAP) ventilation in which a constant level of pressure greater than atmospheric pressure is continuously applied to the upper respiratory tract of a person. The application of positive pressure may be intended to prevent upper airway collapse, as occurs in ...

7. Non-invasive ventilation - Wikipedia

   en.wikipedia.org/wiki/Non-invasive_ventilation

   Non-invasive ventilation (NIV) is the use of breathing support administered through a face mask, nasal mask, or a helmet. Air, usually with added oxygen, is given through the mask under positive pressure; generally the amount of pressure is alternated depending on whether someone is breathing in or out. It is termed "non-invasive" because it is ...
