便携式睡眠检测仪对OSAHS的诊断价值

The diagnosis Value of portable sleep monitor in OSAHS

目的探讨便携式睡眠监测仪在诊断阻塞性睡眠呼吸暂停低通气综合征(OSAHS)中的作用。方法采用泰科Sandman多导睡眠仪(PSG)和瑞思迈Aplink便携式睡眠监测仪,对108例怀疑患有OSAHS的对象采用两种方法进行监测,比较两种诊断方法各指标的差异,以及便携式睡眠监测仪的敏感性、特异性。结果两种方法低通气指数、平均血氧饱和度、最低血氧饱和度、低于90%血氧饱和度时间比较,差异均无统计学意义(P>0.05)。与PSG比较,便携式睡眠监测仪的敏感性为96.8%,特异性为86.7%;对病情分度判断符合率分别为轻度73.3%、中度90.9%、重度100%。结论便携式睡眠监测仪对诊断OSAHS有高敏感性、特异性,可用于临床常规诊断。

Objective To investigate the portable sleep monitor in the diagnosis of obstructive sleep apnea hypopnea syndrome（ OSAHS）,provides an easier,more accurate and lower cost diagnostic method for clinical. Methods 108 patients with suspected OSAHS were monitoted w ith Tyco Sandman polysomnography（ PSG） and Resmed Aplink portable sleep monitor,compare the difference of each parameter provided by the two diagnostic methods as well as to evaluate the sensitivity and specificity of portable sleep monitor. Re sults There was no significant difference in Apnea hypopnea index（ AHI）,the mean SaO_2,the minimal SaO_2,and percentage of time spent at SaO_2 below 90%（ SIT 90%） betw een the two diagnostic methods（ P 0.05）. Sensitivity and specificity of the portable sleep monitor were 96.8% and 86.7% respectively in detecting OSAHS. The corresponse of the specificity of two method was 73.3%（ mild OSAHS）,90.9%（ moderate OSAHS） and 100.0%（ severe OSAHS） respectively according to the degree of OSAHS. Conclusion The portable sleep monitor is highly sensible and more exact especially for the diagnosis of OSAHS,and therefore suitable for routing clinical diagnosis.
