What is the purpose of a CPAP mask?

A CPAP (continuous positive airway pressure) mask is used to deliver continuous positive airway pressure therapy to treat obstructive sleep apnea (OSA). OSA is a common sleep disorder in which the airway becomes repeatedly obstructed during sleep, leading to pauses in breathing. CPAP therapy works by delivering pressurized air to the upper airway through a mask, which helps to keep the airway open and prevent it from collapsing during sleep. CPAP masks come in various types and sizes, and the choice of mask depends on the individual's comfort and needs. The most common types of CPAP masks include nasal masks, full-face masks, and nasal pillow masks.
