Tracheostomy has been employed to release the airway obstruction at the glottic level and to prevent sudden death in patients with multiple system atrophy (MSA). However, sudden death is possible even after tracheostomy. Nocturnal polysomnography showed that the apnea-hypopnea index became higher after tracheostomy, and all tracheostomized patients had frequent central sleep apneas.
气管切开术已被用于解除声门水平的气道阻塞，并预防多系统萎缩（MSA）患者的猝死。然而，即使进行了气管切开术，猝死仍有可能发生。夜间多导睡眠图显示，气管切开术后呼吸暂停低通气指数升高，且所有接受气管切开术的患者都频繁出现中枢性睡眠呼吸暂停。
