Monitoring Results and Correlation Analysis of Polysomnography in 231 Cases of Young Male Patients with Obstructive Sleep Apnea Hypopnea Syndrome

Objective: To analyze the characteristics of polysomnography in the young male patients with obstructive sleep apnea hypopnea syndrome(OSAHS).Methods: Monitoring results of polysomnography(PSG) from 231 young male OSAHS patients were analyzed to learn relationship among the general conditions,apnea and hypopnea events,oxygen reduction and sleep architecture.Results: The rate of overweight and obesity accounted for 93.07% and 75.76%,respectively.The median AHI and LSaO2 were 40.1 times/h and 70%,respectively;the patients with AHI over 40 accounted for 51.95%;LSaO2 between 65% and 85% accounted for 45.45% and with LSaO2 lower than 65% accounted for 40.69%.The percent of the total time with oxygen saturation level90%,85%,80%(TS90,TS85,TS80) accounted for 20.75%,4.53%,1.66%,respectively.REM sleep time was(17.00±7.45)%,and non-REM(NREM) sleep time was(82.96±7.40)%.AHI was negatively correlated with LSaO2 and MSaO2,while it was positively correlated with the others,and had high correlation with ODI and the time of oxygen desaturation in one hour.BMI was negatively correlated with LSaO2 and MSaO2,while it was positively correlated with AHI,ODI,the largest oxygen desaturation degree(LDD).LSaO2 was negatively correlated with LA,LH,TS90,TS85,TS80.Conclusion: The young male patients with OSAHS have high overweight and obesity rate and manifest obvious disorder of sleep structural.
