A Comparative Study On The Diagnosis Of Obstructive Sleep Apnea-hypopnea Syndrome By Micro-movement Sensitive Mattress Sleep Monitoring System And Polysomnography

Objective: To explore the effect of MSMMS and PSG in diagnosing OSAHS,and to provide data support for the diagnosis and clinical promotion of OSAHS by MSMSMS.Methods:One hundred and twelve patients with OSAHS were selected from March2016 to November 2017 in our hospital.All patients underwent PSG and MSMSMS.Obstructive apnea,hypoventilation,AHI,ODI,Sa O2-mean,SaO2-min,TS90%,sleep structure and sleep efficiency index to com-pare the two diagnostic methods in the diagnosis of OSAHS differences.Results:1.There was no significant difference in diagnosis results between MSMSMS and PSG in the number of obstructive apnea episodes,the frequency of low ventilation events,AHI and ODI,P>0.05.However,the results of MSMSMS and PSG were significantly different in SaO2-mean,SaO2-min,TS90%,total sleep time,sleep result and sleep efficiency,P <0.05,the difference was statistically significant.2.There was a significant linear correlation between MSMSMS and PSG in obstructive apnea,hypopnea,AHI,ODI,SaO2-mean,SaO2-min and TS90% MSMSMS and PSG in total sleep time there is a certain correlation,P<0.05,the difference was statistically significant.There was no significant correlation between MSMSMS and PSG in terms of sleep architecture and sleep efficiency.3.The diagnostic accuracy of MSMSMS increases with the severity of OSAHS and the highest is the diagnostic accuracy of severe OSAHS.4.The diagnostic accuracy of MSMSMS increases with the severity ofnocturnal hypoxemia and the highest diagnostic accuracy for severe nocturnal hypoxemia.Conclusion:Compared with PSG diagnostic method,MSMSMS has certain diagnostic value for OSAHS,especially for patients with moderate-severe OSAHS,its accuracy is relatively high,worthy of clinical promotion.
