Abstract

To identify the clinical characteristics of sleep apnea syndrome in Korean, author analyzed 24 cases of polysomnographic findings statistically, diagnosed as sleep apnea syndrome during May, 1995 to July, 1996. The results were summarized as follows : 1. The mean age of subjects was 35.7 years, the distribution of age was 12 to 64 years, and male to female sex ratio was 5=1. 2. As for mean values of sleep parameters, total bed time was 429.8 minutes, waking after sleep onset was 93.4 minutes, total sleep time was 336.1 minutes and sleep efficiency was 77.7%. 3. The proportions of sleep stage 1, stage 2, slow wave sleep, REM sleep, and movement time to total sleep time were 13.1%, 39.4%, 24.4%, 20.8%, and 2.2% respectively. 4. Mean AKapnea index) was 28.7 and RDKrespiration disturbance index) was 34.3. 5. Waking after sleep onset correlated with total sleep time and sleep efficiency negatively, and with sleep stage 1 positively. Sleep efficiency correlated with sleep stage 1 negatively, and sleep stage 1 correlated with slow wave sleep negatively.
