Objective: Obstructive sleep apnea syndrome(OSAS)is a type of sleep respiratory disease caused by several factors.It causes hypoventilation at night,which in turn results in excessive daytime sleepiness.The common clinical reason of OSAS is upper airway stenosis.Long-term nocturnal apnea and hypoventilation induce hypoxia in the body.Intermittent hypoxia affects various systems of the body,including the blood,nervous,and endocrine systems.The harmful effects produced by intermittent hypoxia are extensive and irreversible and may even result in sudden death during sleep.
