Abstract:
[ABSTRACT]OBJECTIVETo assess the sleep body position's effects on AHI and ODI during sleep in obstructive sleep apnea hypopnea syndrome (OSAHS) patients with different severity.METHODSThe clinical data of 113 subjects who had been diagnosed OSAHS or normal by polysomnography (PSG) between 2013 and 2014 in our department were retrospectively studied. They were divided into normal control group (AHI<5/h, 41 patients), mild to moderate OSAHS group (5/h30/h, 40 patients). PSG data of AHI and ODI in different body position in each group were further analyzed.RESULTSIn normal group, The AHI and ODI in supine position were significantly higher than that in the left or right lateral position, and the difference between the left and right lateral position was not significant. In the mild to moderate OSAHS group, the AHI and ODI in supine were higher than that in the left lateral position slightly, while the data in supine was higher than that in the right lateral position significantly. In the severe group, the data between the supine and the left lateral position was not statistically different, while the supine position data was higher compared with that of the right lateral position. CONCLUSIONAHI and ODI were higher in supine position than that in lateral position, while the AHI and ODI in right lateral position is higher than that in left lateral position in OSAHS patients with different severity. The ODI and AHI are consistent in reflecting the severity of the OSAHS.
