CPAP masks

A mask system includes the CPAP mask and the air tubing. Air tubing is fairly standard, but CPAP masks (or CPAP headgear) hold the most competitive portion of the CPAP accessories. There exists a much broader range of comfort levels in current CPAP headgear systems than in flow generators.
There are 2 basic kinds of CPAP masks:

Nasal CPAP masks for the majority of sleep apnea patients. These CPAP masks cover only the nose.

Full face CPAP masks designed for sleep apnea patients who breathe through their mouths, these CPAP masks cover the nose and mouth.
