CPAP machines are essential devices in sleep therapy, designed to alleviate the symptoms of sleep apnea. It stands for Continuous Positive Airway Pressure, and these machines work by delivering a continuous and steady stream of pressurized air through a connected mask. The primary goal is to prevent the airway from collapsing during sleep, ensuring a consistent flow of oxygen and reducing interruptions in breathing.

These machines consist of a motor that generates the airflow, a humidifier to add moisture to the delivered air, and a mask that fits over the nose, mouth, or both. The pressurized air created by the CPAP machine acts as a pneumatic splint, preventing the collapse of soft tissues in the throat that leads to sleep apnea episodes.
