阻塞型睡眠呼吸中止症候群多發生在中年人，英文簡稱為OSA S。儘管醫學界對於此疾病的狀況和診斷方法都比以前進步很多，許多患者仍然是沒有被診斷出來，沒有接受治療，原因是多數的患者並無明顯的臨床症狀的困擾，醒來時也很少感到呼吸困難。OSAS 易引起高血壓、心血管疾病和中風。許多研究證實持續性呼吸道正壓治療和調整生活形態對OSAS 患者有許多好處。本文主要目的即是在介紹阻塞型睡眠呼吸中止症候群定義、症狀、治療與生活型態的調整，以提供OSAS 患者自我照護的指引。

Obstructive sleep apnea syndrome （OSAS） is common in middle age adults. Despiteincreasing awareness of the condition and improved diagnostic procedures, most patients remain undiagnosed and untreated because most patients do not have obvious torment by symptoms, and rarely aware of having difficulty breathing, even upon awakening.OSAS is an independent risk factor for hypertension and is associated with cardiovascular and cerebrovascular morbidity. The benefits and effects of continuous positive airway pressure （CPAP） treatment and life-style adjustment have been described in many prospective studies.This paper introduces the definition, symptoms and treatment of OSAS,as well as life-style adjustment for the guidance of self-management in patients with OSAS.
