摘要
目的比较便携式与多导两种睡眠监测仪在诊断睡眠呼吸暂停综合征(obstructivesleepapneasydrom,OSAS)中作用的导同,为临床应用更简易、准确、低成本的诊断方法提供参考。方法采用某进口的多导睡眠仪和便携式睡眠监测仪,对50例怀疑有OSAS的对象同时进行监测比较两种诊断方法各指标的差异,以及便携式监测仪的敏感性、特异性。结果两种方法所得结果呼吸紊乱指数、氧减指数、平均血氧饱和度、最低血氧饱和度、低于90%的血氧饱和度时间等均无显著性差异(P>0.05)。与多导睡眠监测仪比,便携式睡眠监测仪的敏感性为100%,特异性为60%;对病情分度判断的符合率分别为轻度73.3%、中度71.4%、重度94.4%。结论便携式睡眠监测仪对诊断OSAS有高敏感性,尤其对重度OSAS的诊断更为准确,适合于临床常规诊断。具体应用时应注意选择有口鼻气流的传感。
Objective To offer an easier, more accurate and lower cost diagnostic method by comparison between the portable sleep monitor and the polysomnography in the diagnosis of the obstructive sleep apnea syndrome（OSAS）. Methods 50 cases with suspected OSAS were monitored with imported portable sleep monitor and the polysomnography simultaneously so as to 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. Results There was no significant difference in respiratory disturbance index （RDI）, saturation impair time index （SIT）, the number of oxygen desaturation index≥4% per hour（DI4）, the mean SaO2 .the minimal SaO2, and percentage of time spent at SaO2 below 90% （SIT90%） between the two diagnostic methods （ P〉0.05）. Sensitivity and specificity of the portable sleep monitor were 100% and 60% respectively in detecting OSAS. The corresponse of the specificity of two method was 73.3% （mild OSAS）. 71.4% （moderate OSAS） and 94.4% （severe OSAS） respectively according to the degree of OSAS. Conclusions In the diagnosis of OSAS, the portable sleep monitor is highly sensible and more exact especially for severe OSAS, and therefore suitable for routing clinical diagnosis. Nasal airflow transducer should be chosen in this case.
