Abstract:
Objective To evaluate the application value of the micro movement sensitive mattress sleep monitoring system(MSMSMS) in the diagnosis of children with obstructive sleep apnea syndrome (OSAS).Methods One hundred and twenty-nine children aged from 3 to 14 years who visited the sleep center of Beijing Children's Hospital Affiliated to Capital Medical University from June 2013 to June 2015 due to sleep snoring were enrolled.Children with acute respiratory infection,cranial facial abnormalities,chronic lung diseases and neuromuscular diseases were excluded.According to the criteria,36 children were diagnosed as OSAS with average age of (7.3 ± 2.5) years,including 28 males and 8 females.Ninety-three non-OSAS children were recruited with average age of (6.3 ± 2.3) years,including 61 males and 32 females.Subjects were monitored with polysomnography(PSG) and MSMSMS simultaneously.Apnea/hypopnea index (AHI) ＞ 5 or obstructive apnea index (OAI) ＞ 1 were used to define whether OSAS existed.The consistency between MSMSMS and PSG in the diagnosis of OSAS and the determination of sleep efficiency were compared.Results The Kappa consistency coefficient of MSMSMS and PSG in the diagnosis of OSAS was 0.70(95％ CI:0.57-0.84),Z =7.99,P ＜ 0.000 1,which indicated the consistency between PSG and MSMSMS was good.The consistency of sleep efficiency of MSMSMS and PSG were compared.Bland-Altman results showed that there were 3％ (5/129 cases)points out of 95％ consistency bound and the interclass correlation coefficient (ICC) was 0.69 which indicated the consistency of 2 methods was good in determination of sleep efficiency.MSMSMS was able to detect respiratory event that was associated with sub-cortical arousals with no electroencephalogram arousal or blood oxygen reduction.Conclusions There is an adequate consistency between MSMSMS and PSG in the diagnosis of children with OSAS and determination of sleep efficiency.The MSMSMS has an advantage in detection of sub-cortical arousals and respiratory event.
