微动敏感床垫式睡眠监测系统诊断阻塞性睡眠呼吸暂停及睡眠参数一致性评价OACSTPCD

Objective To evaluate the consistency of multiple parameters between the Micro-Motion-Sensitive Mattress Sleep Monitoring System(MSMSMS)and polysomnography(PSG)in the diagnosis of obstructive sleep apnea(OSA)and sleep assessment.Methods Sixty-seven subjects suspected of having OSA underwent PSG and MSMSMS simultaneously to record multiple sleep parameters.The consistency between PSG and MSMSMS in the diagnosis and grad-ing of OSA,as well as the consistency in respiratory events,blood oxygen events,sleep basic information,and sleep structure parameters,was compared.Paired t-test,Bland-Altman analysis,and intraclass correlation coefficient(ICC)were used for continuous data,and weighted kappa analysis was used for categorical data.Results Compared with PSG,the areas under the curve for diagnosing mild,moderate,and severe OSA were 1,0.999,and 0.967,respectively(P＜0.001);the weighted kappa coefficient for the two diagnostic results was 0.841(95％CI:0.766-0.928,P＜0.001).The intraclass correlation coefficients of the apnea-hypopnea index(AHI),apnea index(Al),and blood oxygen indexes were 0.967(0.943,0.980),0.937(0.900,0.961),and 0.900(0.837,0.939),respectively,and 0.936(0.891,0.962).Except for the hypopnea index(HI)[0.181(-0.032,0.387),P=0.036],there was high consistency in the interpretation of other respiratory events and blood oxygen indexes(P＜0.001).There was a moderate level of consis-tency between the two methods in the interpretation of sleep structure,including the proportion and time of light sleep and the time of deep sleep.Conclusion MSMSMS has high sensitivity and specificity in the diagnosis and grading of OSA compared with PSG.In addition to strong consistency in respiratory events and blood oxygen indexes,MSMSMS also has certain significance in evaluating the sleep structure of OSA patients.
