This document discusses obstructive sleep apnea (OSA). It notes that OSA is a common disorder characterized by apneas, hypopneas and respiratory event related arousals during sleep that can cause excessive daytime sleepiness, fatigue, and poor concentration. It outlines the prevalence of OSA, risk factors such as age, obesity and craniofacial abnormalities, clinical manifestations including snoring and cardiovascular issues, diagnostic tests including polysomnography, and treatments including positive airway pressure and lifestyle changes.
