To identify the clinical characteristics of sleep apnea syndrome in korean, author tried statistical analysis of 24 cases of polysomnographic findings diagnosed as sleep apnea syndrome during December, 1993 to November, 1994.
@ES The results were summarized as follows.
@EN 1. Distribution of the subtypes of sleep apnea syndrome according to AI, the obstructive type was 23 cases, central type was 4 cases and mixed type was 6 cases, and most frequent dominant type was obstructive type.
2. As for sleep parameters, mean total sleep time was 303.6 minutes, WASO was 123.8 minutes, movement time was 6.2 minutes, sleep efficiencies was 71.3%, stage 1 sleep time was 58.8 minutes (19.4%) stage 2 sleep time was 136.2 minutes(44.9%),
slow
wave
sleep time was 53.5 minutes(17.6%), REM sleep time was 49.4 minutes(16.3%), and non-REM sleep time was 248.5 minutes(81.9%).
3. Correlations among sleep parameters diagnosed as obstructive type SAS, WASO was negative correlation with total sleep time, non-REM sleep time was positive correlation with total sleep time and negative correlation with WASO. Sleep
efficiencies
was
positive correlation with total sleep time and non-REM sleep time, and negative correlation with WASO. And, slow wave sleep time was negative correlation with stage 1 sleep time and stage 2 sleep time.
Above results were thought to be as useful data in clinical practice for the explanation of characteristics of korean sleep apnea syndrome.
