微动敏感床垫式睡眠监测系统对老年OSAHS患者监测结果分析

Analysis of monitoring results of Mattress-type of sleep monitoring system in elderly patients with OSAHS

目的:探讨老年阻塞性睡眠呼吸暂停低通气综合征OSAHS患者微动敏感床垫式睡眠监测的特点。方法:对190例OSAHS患者按照年龄分为老年组和非老年组,行床垫式睡眠监测,对其结果进行分析,以了解老年OSAHS患者的床垫系统睡眠监测特点。结果:老年组患者的病情程度以轻、中度居多。老年患者夜间平均血氧及最低血氧均高于非老年组,但血氧饱和度<90%占监测总时间的百分比(TS90)高于非老年组。睡眠结构比较两组资料无显著性差别,但老年组的睡眠总时间要低于非老年组,差异有统计学意义。结论:老年人OSAHS患者的病情较轻;但老年组患者的夜间低氧状态持续时间更长;老年组的睡眠结构较非老年组无明显差异,但睡眠总时间减少。床垫式睡眠监测系统的干扰小,更接近受试者自然睡眠状态。

Objective：To investigate the sleep monitoring feature of the MSMS in elderly patients with OS- AHS. Method.. One hundred and ninety patients diagnosed with OSAHS were divided into elderly group and non elderly group according to age, then the results of MSMS were analyzed. Result： Majority elderly patients were with mild to moderate OSAHS. The nocturnal mean blood oxygen and the lowest oxygenwere higher than non eld- erly group, coupled with higher percentage of the total oxygen saturation 〈90% monitoring time （TS90）, There was no significant difference in sleep structure between two groups, but the total sleep time of elderly group is lower than the non elderly group, the difference is statistically significant. Conclusion.. The elderly patients with OSAHS were less severe in nature, but the nocturnal hypoxia last longer in the elderly group. There is no signifi- cant difference in the sleep structure between the two groups. But the total sleep time decrease in elderly group. With smaller interference, the MSMS is closer to the natural sleep stustus of the subjects.
