中枢性睡眠呼吸暂停的原因及临床基本特征

Causes and clinical features of central sleep apnea

中枢性睡眠呼吸暂停（CSA）是一类以睡眠期间呼吸努力消失所致呼吸暂停为主要特征的睡眠呼吸障碍。相对于阻塞性呼吸暂停，虽然其发生率更低且常不被了解，但引起CSA的因素众多，分类也较复杂，临床意义各异。本文就不同原因所致CSA及基本特征进行了介绍。

Central sleep apnea （CSA） is a kind of sleep-disordered breathing, which is characterized by temporary loss of inspiratory ventilatory effort during sleep. In contrast to obstructive sleep apnea, CSA has lower prevalence clinically and may be less understood, however, central apneas occur in many pathophysiological conditions and result in pathophysiologieai consequences, depending on different causes or mechanisms. The causes and basic clinical features of CSA were introduced in this paper.
