Abstract:
Objective To analyze the relationship between daytime sleepiness and oxygen desaturation in the male eldcrly with obstructive sleep apnea /hyponea syndrome (OSAHS).Methods 147 male elderly (aged 60-80 years) with OSAHS in our sleep laboratory from March 2008 to February 2011 were divided into daytime sleepiness and daytime non-sleepiness groups. Epworth sleeping scale (ESS) and polysomnography (PSG) were employed to detect the degree of sleepiness.Oxygen desaturation were evaluated by oxygen desaturation index (ODI),average and minimum blood oxygen,time percentage of 90％ oxygen desaturation (CT90). Resulls There were significant differences between the two groups in body mass index (BMI) (t=4.157),ODI (t=-10.063),average (t=5.800) and minimum (U=916) blood oxygen,CT90(U=887)and apnca/hypopneaindex (AHI) (t =-11.361) (all P＜0.001).ESS scores were related with desaturation parameters of ODI,average and minimum blood oxygen and CT90 (r=0.683,-0.450,-0.583,0.507,all P＜0.001).ODI was correlated with average and minimum blood oxygen and CT00 (r=-0.628,-0.763,0.689,all P＜0.001).Among parameters of oxygen desaturation,only ODI had influence on ESS scores (odds ratio=1.11,95％CI:1.07 1.15),The sensitivity and specificity predicting daytime sleepiness at ODI ≥23 times/h were about 79.2％ and 84.3％,respectively.Conclusions Daytime sleepiness is associated with oxygen desaturaion and may be predicted by ODI through which average and minimum blood oxygen and CT00 are related with daytime sleepiness in the male elderly with OSAHS.
