Abstract:
Objective To evaluate the diagnostic value of micro-movement sensitive mattress sleep monitoring system (MSMSMS)in children with obstructive sleep apnea hypopnea syndrome.Methods Sixty-five children with the complaint of sleep disorder were collected and detected by polysomnography and micro-sensitive mattress sleep monitoring system overnight at least seven hours.The date from two instruments were analyzed by computer automatically and then modified by two professional staff double-blind separately.The data about the diagnosis of sleep breath disorder and other sleep physiology information were compared between the two groups.Results Sixty-one cases finished the study finally.The mean age of these children was (7.0 ± 2.7) and the youngest was 3 years old,maximum was 13 years old,male children 46 cases,female patients 15 cases,body mass index (BMI) median [25 quantile; 75 quantile] 16.00[14.80;17.65]kg/m2.Mean PSG measured apnea hypopnea index (AHI) was 4.50[2.30;10.15] times/h,and mean MSMSMS AHI was 3.63 [2.56 ;6.43] times/h.There was a significant correlation between PSG AHI and AHI by MSMSMS(r =0.935,P ＜0.01).A Bland-Altamplot of PSG AHI and MSMSMS AHI was also used to assess the accuracy of MSMSMS.95.1％ of the data was fallen in the 95％ consistency areas.For AHI ≥5 times/h and nighttime minimum oxygen ＜ 91％ or obstructive apnea index (OAI) ＞ 1 time/h and nighttime minimum oxygen saturation ＜ 91％ as threshold value,the MSMSMS diagnosing sensitivity and specificity were 82.9％ and 92.3％.The misdiagnosis rate and missed diagnosis rate were 7.7％ and 17.1％.Conclusions The MSMSMS offer a simple and comfortable method to monitor children's sleep.It improves the compliance in the process of sleep monitoring.Besides,as a diagnostic tool in the diagnosis of OSAHS on children has a high credibility in AHI.
