A CPAP (continuous positive airway pressure) machine is a device used to treat sleep apnea, a condition where breathing is interrupted during the sleep cycle, leading to a lack of oxygen and a higher risk for health concerns such as high blood pressure, heart disease, stroke, and diabetes. The machine delivers continuous pressurized air through tubing into a mask that you wear while you sleep, helping to keep your airways open by preventing them from collapsing. The machine has three main components: a mask, a hose, and a motor that generates a continuous stream of pressurized air that travels through an air filter into a flexible tube. The machines pressure level can be set with the help of a doctor, and there are different types of CPAP machines, including Bi-level PAP and Auto CPAP. CPAP machines are one of the leading treatments for sleep apnea, and they can have a positive impact on peoples lives if used correctly. However, they can be uncomfortable for some people, and it is important to use them correctly to ensure they work effectively.
