Objective To evaluate the application value of smartphone software Sleepok based on snoring analysis technology in adult obstructive sleep apnea(OSA),and to compare its predictive value with the commonly used OSA screening scales for OSA.Methods One hundred and seventy-three adult subjects who came to the clinic in the Depart-ment of Respiratory and Sleep Medicine of Peking University People's Hospital from July 2022 to April 2023 due to sno-ring and underwent polysomnography(PSG)were enrolled.Sleepok was used to monitor snoring during PSG monitoring.On the night of monitoring,the subjects completed a paper questionnaire(including basic information and commonly used OSA screening scales)under the guidance of the researchers.Results There was not significant difference between apnea hypopnea index(AHI)obtained by Sleepok and that obtained by PSG(P＞0.05).The results of Pearson regres-sion analysis showed that Sleepok_AHI had a good correlation with PSG_AHI(r=0.80,P＜0.001).Bland-Altman consis-tency test results showed that Sleepok_AHI and PSG_AHI had higher consistency(P=0.118),and their average differ-ence was only-1.82 events/hour.The results of receiver operating characteristic(ROC)curve analysis showed that Sleepok_AHI had better diagnostic value in OSA,moderate to severe OSA and severe OSA,and their cut-off values were 16.6 events/hour,18.9 events/hour and 28.0 events/hour,respectively.There were significant differences in the scoring values of 6 scales(No-Apnea,GOAL,NoSAS,STOP,STOP-Bang,CNCQ-OSA)and Sleepok_AHI level between the simple snoring group and the OSA group(P＜0.05).The results of ROC curve analysis showed that all the 6 scales had application value in diagnosing OSA(P＜0.05).Conclusion The smartphone software Sleepok based on snoring analysis technology can effectively identify respiratory events during sleep,and has better sensitivity and specificity for the patients at high risk of OSA,and can be used for OSA screening.
