Continuous Positive Airway Pressure, or CPAP, is a medical treatment commonly used for individuals with sleep apnea. It involves a machine that delivers a steady stream of air through a mask worn over the nose or mouth during sleep. This airflow helps keep the airways open, preventing interruptions in breathing. The CPAP device is designed to improve sleep quality and reduce daytime fatigue by ensuring that the user receives adequate oxygen throughout the night. Regular use of CPAP can lead to better overall health and a lower risk of complications associated with untreated sleep apnea.
