便携式睡眠监测与多道睡眠监测相关性初步研究

A preliminary study of correlation between portable sleep monitoring and laboratory polysomnography

目的探讨便携式睡眠监测系统与实验室多道睡眠监测(PSG)的一致性及相关性,评估其诊断阻塞性睡眠呼吸暂停低通气综合征(OSAHS)的价值。方法采用PSG和便携式睡眠监测仪,对39例OSAHS疑似患者进行同步睡眠监测。比较两者的呼吸暂停低通气指数(AHI)、呼吸暂停低通气次数(AH)、呼吸暂停指数(apnea index,AI)、低通气指数(hypopnea index,HI)、平均动脉氧饱和度(mean SaO2,MSaO2)、最低动脉血氧饱和度(lowest SaO2,LSaO2)、SaO2≤90%的累积时间占总监测时间的百分比(CT90%)、总睡眠期时间(total sleep time,TST),并分析其相关性。结果 PSG示非OSAHS 4例,OSAHS 33例,其中轻度2例,中度4例,重度27例;便携式睡眠监测示非OSAHS 4例,OSAHS 33例,其中轻度5例,中度3例,重度25例,诊断符合率为100%,轻、中、重度一致率分别为40%、75%、92.6%。便携式睡眠监测系统与PSG比较,除AHI、AH、AI差异有统计学意义外,HI、MSaO2、LSaO2、CT90%、TST差异均无统计学意义(P>0.05)。结论便携式睡眠监测仪是一种简单易操作的监测设备,其诊断符合率为100%,但对于疾病严重程度判断仍有待提高。

OBJECTIVE To evaluate the consistency and relevance of the portable sleep monitoring system and laboratory polysomnography in the diagnosis of obstructive sleep apnea hypopnea syndrome（OSAHS）.METHODS Thirty nine cases with suspected OSAHS received laboratory polysomnography and portable sleep monitor synchronously.The parameters of apnea hypopnea index（AHI）,apnea hypopnea（AH）,apnea index（AI）,hypopnea index（HI）,mean oxygen saturation（MSaO2）,lowest oxygen saturation（LSaO2）,percentage of time with an oxygen saturation below 90%（CT90%）,and total sleep time（TST）were collected and analyzed.Paired Rank Test was adopted and P0.05 was accepted as statistically significant.RESULTS The laboratory polysomnography showed 4 non-OSAHS cases,33 cases met the diagnostic criteria for OSAHS,including 2 mild cases,4 moderate cases and 27 severe cases.Portable sleep monitor showed 4 non-OSAHS patients and 33 OSAHS patients,5 mild cases,3 moderate cases and 25 severe cases.The diagnostic accuracy was 100% and the concordance rates of diagnostic accuracy in mild,moderate and severe patients were 40%,75% and 92.6%.In addition,the parameters of AHI,AH and AI had statistically significant difference,while HI,MSaO2,LSaO2,CT90%,and TST had no significant difference（P0.05）.CONCLUSION The portable sleep monitor is a helpful and simple equipment in the identification of patients with OSAHS for it provides effective data for clinical diagnosis.But the diagnostic accuracy in the severity of the disease must be improved.
