摘要: 目的: 根据多导睡眠仪的监测结果,分析中青年重症阻塞性睡眠呼吸暂停综合征(obstructivesleepapneasyndrome,OSAS)患者的特点。方法: ①对经多导睡眠仪确诊的16例重症OSAS患者的多导睡眠仪(polysomnography,PSG)信号进行分析。16例患者中35岁以下的青年人8例,4 0岁以上的中年人8例。②比较两组患者各睡眠时相的呼吸事件所占的百分数。③比较两组患者的体块指数(bodymassindex,BMI)、紊乱指数(apneaandhypopneaindex,AHI)、氧减指数(saturationimpairtimeindex,SIT90-70)、平均氧饱和度、最低氧饱和度、平均呼吸暂停时间及最长呼吸暂停时间。结果: ①青、中年患者Ⅱ期睡眠中呼吸事件所占的百分数有显著差异。Ⅰ、Ⅲ+Ⅳ期睡眠中呼吸事件所占的百分数青年组均比中年组高,但无统计学意义。②两组患者AHI指数、氧减指数、最低氧饱和度、平均氧饱和度均有显著差异。结论: ①中青年患者非快动眼睡眠(non-rapid-eye-movement,NREM)中呼吸事件发生的频率存在差异。②青年患者 AHI 和 SIT90-70高于中年患者,最低氧饱和度、平均氧饱和度低于中年患者。Abstract: Objective: To analyse the characteristics of OSAS patients in the young and the middle-aged. Methods: 1.Analyse the PSG signals of 16 patients proved by PSG with serious OSAS.Of the 16 patients,there were eight young men under 35 and the other eight middle-aged men beyond 40. 2.The percent of respiratory events in each sleep stage were compared in the two groups. 3.The body mass index（BMI）、apnea and hypopnea index（AHI）、saturation impair time index（SIT90-70）、mean apnea time、longest apnea time、mean SaO2 and lowest SaO2 were compared in the two groups. Results: 1.The percent of respiratory events in stageⅡ of the two groups is different. 2.The AHI、SIT 90-70、mean SaO2、lowest SaO2 of the two groups are different. Conclusion: 1.The percent of respiratory events of the two groups in NREM is different. 2.The AHI and SIT 90-70 of the young are higher than of the middle-aged.The mean SaO2 and the lowest SaO2 of the young are lower than of the middle-aged.
