There are several methods for measuring the severity of OSA. These include measuring the number of apnea and hypopneas per hour of sleep (apnea-hypopnea index: AHI), the degree of oxygen desaturation during sleep, or the severi ty of daytime sleepiness, which is the most common condition that negatively affects the quality of life. The gold standard test for the diagnosis of OSA is polysomnography. The pulse oximeter, home sleep apnea testing, SleepQuest device, peripheral arterial tonometry, ApneaLink Plus device, maximum static inspiratory pressure, and maximum static expiratory pressure measurements are preferred methods for OSA diagnosis. © 2021, IGI Global.eninfo:eu-repo/semantics/closedAccessBook Chapter385110.4018/978-1-7998-8018-9.ch0032-s2.0-85128286564N/A
