老年阻塞性睡眠呼吸暂停综合征患者睡眠监测及临床特点分析

目的分析老年阻塞性睡眠呼吸暂停综合征（obstructive sleep apnea syndrome OSAS）患者的多导睡眠监测特点。方法比较中青年组72例、老年组42例的多导睡眠监测（polysomnography，PSG）资料及临床资料。结果老年组呼吸暂停低通气指数（apnea hypopnea index，AHI）、微觉醒指数（arousal index，ArI）与中青年组相比均较低，最低血氧饱和度（SaO2）与中青年相比却较高，睡眠结构两组类似，差异无显著性，P〉0．05；老年OSAS中打鼾、夜间憋醒、觉醒时头痛、白天困倦等症状与中青年患者比较较轻，但各系统并发症较多，差异有显著性。结论老年组OSAS患者呼吸紊乱及缺氧程度较轻，临床症状较轻但睡眠结构紊乱的程度与中青年组基本接近。

Polysomnography and clinical characteristics of elder patients with obstructive sleep apnea syndrome

Objective To analyze the polysomnography result and clinical characteristics of elder patients with obstructive sleep apnea.Methods Comparisons were made on the polysomnography and clinical data between 72 young or middle aged patients and 42 elderly patients with obstructive sleep apnea syndrome.Results The apnea hypopnea index (AHI) and arousal index (ArI) in the elder patients were lower,but the lowest arterial oxygensaturation was higher in the elder patients. The sleep structure was similar in the two ...
