A CPAP (Continuous Positive Airway Pressure) machine is a medical device used primarily to treat sleep-related breathing disorders such as obstructive sleep apnea (OSA). It works by delivering a continuous stream of mild, pressurized air through a mask worn over the nose and/or mouth during sleep. This steady airflow helps keep the airways open, preventing them from collapsing or becoming blocked, which allows for normal breathing throughout the night
. The machine consists of a motor that pressurizes room air, a hose that delivers the air, and a mask that fits over the nose or mouth. Some CPAP machines include additional features like heated humidifiers to improve comfort and adjustable pressure settings. The pressure is constant and set to a level prescribed by a healthcare provider to maintain airway patency during both inhalation and exhalation
. CPAP therapy improves sleep quality, reduces the risk of cardiovascular problems such as heart attack and stroke, lowers blood pressure, and decreases daytime sleepiness. However, some users may experience side effects like discomfort, nasal congestion, dry mouth, or skin irritation from the mask
. In summary, a CPAP machine is a device that helps people with sleep apnea breathe continuously and comfortably during sleep by keeping their airways open with a constant flow of pressurized air
