“…Although resting blood pressure of OSA patients was significantly higher than that of control group, it was ranged in normal value at the upper border line. AHI of PSG had a highly positive correlation with the oxygen desaturation index (ODI) of pulse oximetry [42] which was consistent with the study of Oeverland and his colleagues [43]. They showed that AHI values were more reliable than ODI.…”

“…The severity of sleep ap- nea in the volunteers was quantified by the 3% oxygen desaturation index (3%ODI), which was the number of oxygen desaturations of 3% or more below the baseline level per hour during sleep. This index correlates well with the conventional AHI (26). Subjects who had a 3%ODI of Ͻ5 were diagnosed as not having OSA.…”

“…Due to this correlation, the ODI/AHI ratio was considered to be a factor that roughly corrects the desaturation frequency for the apnoea-hypopnoea frequency and that its variation reveals that factors other than ventilation could be involved. Although the correlation is good in a group of OSA subjects, large variations are actually found when AHI and ODI are compared between individual subjects [27]. In the whole group of 209 subjects with OSA, the AHI values were generally higher than the ODI values, with a mean difference of 15.8 and a considerable scatter (SD 13. even though the OSA is more severe in this latter subject.…”

“…The ODI and AHI values were fairly well correlated with each other among those 209 OSA subjects from whom the 30 study subjects were selected (r50.8, p,0.01). Also in the literature, ODI is generally considered to be positively correlated with AHI in OSA subjects [27]. Due to this correlation, the ODI/AHI ratio was considered to be a factor that roughly corrects the desaturation frequency for the apnoea-hypopnoea frequency and that its variation reveals that factors other than ventilation could be involved.…”
