便携式睡眠监测与多导睡眠监测临床应用差异性比较

目的 比较便携式睡眠监测(PM)与多导睡眠监测(PSG)两种方法在临床上诊断阻塞性睡眠呼吸暂停综合征(OSAS)的差异性,为PM在临床中的应用提供参考.方法 对84例疑似OSAS并已行PSG的入选者行PM,将两组监测结果进行统计分析,比较其各主要参数的差异性,并分析PM的准确度.结果 两种监测方法在呼吸紊乱指数、氧减指...

Comparison of the clinical usage between unattended portable monitors and polysomnography

Objective To offer recommendations of the clinical application of portable monitors (PM) by comparison between the PM and polysomnography (PSG) in diagnosis of the obstructive sleep apnea syndrome (OSAS). Methods 84 candidates who already underwent PSG were monitored by PM to compare the difference of each parameters between the two methods as well as the accuracy of PM was evaluated. Results There was no significant difference in apnea hypopnea index (AHI) ,saturation impair time index (SIT) ,the minimal SaO2 ,and the mean SaO2 between the two diagnostic methods ( P ＞0.05).Sensitivity and specificity of the PM were 98.31 % and 80 %, LR+ = 4.915 5, LR_ = 0. 0135 2, PV+ =0. 142 9,PV_ = 0. 999 3. Conclusions PM may be utilized as an alternative diagnostic test for OSAS based in part on the premise that it is highly sensible and more exact especially for moderate and severe OSAS or as a test evaluated the treatment of OSAS by taking a follow-up visit on patients. PM is not appropriate for the diagnostic evaluation of OSAS in patients suspected of having other sleep disorders.
