Objective: The aim of this study was to evaluate the differences in the polysomnography data between positional and non-positional obstructive sleep apnea (OSA) patients.
Methods: Forty-seven patients diagnosed with OSA were evaluated using full night polysomnography. According to the criteria of Cartwright et al., the patients were classified into two groups with 37 positional (supine apnea-hypopnea index [AHI] ¡Ã 2x¡¯s the lateral AHI) and 10 non-positional (supine AHI £¼ 2x¡¯s the lateral AHI) OSA patients, and the differences of polysomnography data between the two groups were evaluated.
Results: There were no significant differences in demographic variables (age, gender, and BMI), daytime sleepiness, overall AHI, total arousal index, and percent time of snoring between two groups. However, AHI, arousal index, and mean oxygen saturation (SpO©ü) of the REM sleep stage were significantly more severe in the positional OSA group than the non-positional OSA group. Mean SpO©ü and the lowest SpO©ü during overall sleep stage were also significantly lower in the positional OSA group than the non-positional OSA group.
Conclusions: Our results of differences in the polysomnography data of REM sleep stage suggest that non-positional OSA patients may have higher collapsibility of the oropharyngeal airway during sleep than positional OSA patients.
