Watch PAT 200便携式睡眠呼吸监测仪对阻塞性睡眠呼吸暂停低通气综合征监测价值研究

Assessment of a portable monitoring device Watch PAT 200 in the diagnosis of obstructive sleep apnea hypopnea syndrome

目的:评价腕式睡眠呼吸监测仪(Watch PAT 200)对阻塞性睡眠呼吸暂停低通气综合征(OSAHS)的诊断价值。方法:28例怀疑有OSAHS的患者入院行整夜PSG监测和腕式Watch PAT 200监测。PSG监测根据标准规则判断睡眠呼吸事件;Watch PAT 200监测根据计算机自动运算法则进行分析,计算每小时呼吸事件频率,监测外周动脉容积信号变化、氧饱和度及心率变化,根据变化综合得出睡眠呼吸暂停指数(PAT AHI)。结果:平均PSG AHI(23.00±21.55)/h,平均PAT AHI(25.99±19.09)/h,PSG AHI和PAT AHI指数间显著相关(r=0.92,P<0.01),为评估PAT检测的敏感度和特异度,构建ROC曲线,在PSG AHI分别为5、15、30时,PAT监测的敏感度和特异度分别是95.8/100,93.7/91.7,85.7/100。每30s一屏PSG及PAT对睡眠及觉醒判断的符合率为(89±6)%。结论:腕式睡眠监测仪是一种精确检测OSAHS的装置,监测简便,且能准确判断睡眠及觉醒状态。

To assess the accuracy of a wrist worn Watch PAT 200 in diagnosing obstructive sleep apnea hypopnea syndrome（OSAHS） by comparing with the standard polysomnography（PSG）. Method： Twenty- eight adults with suspected OSAHS underwent a standard inqab PSG while wearing a Watch PAT 200. PSG e- vents were manually scored according to standard criteria（AASM）. Watch PAT data were collected including changes of apnea hypopnea, sleep stages, peripheral arterial volume, signal oxygen saturation and heart rate, and then apnea hypopnea index（AHI）was analyzed by an automatic algorithm. Result： For PSG, the mean score of AHIwas（23.00~21.55）/h, and for Watch PAT, ameanscoreofAHlwas（25.99＋_19.09）/h. There isastatis- tically positive correlation between PSG-AHI and PAT-AHI（r--0. 92,P^0. 01）. The Coincidence rate of the sleep wake assessment based on 30 second bins between the PSG and Watch PAT 200 was（89±6）%. Conclusion： Watch PAT 200 could detecte OSAHS based on AH｜ with comparable accuracy with standard PSG. And it would provide a reasonably accurate estimation of sleep and wakefulness stages in patients with OSAHS.
