Conventional and novel hypoxemia-related indices for obstructive sleep apnea severity and incident hypertension: a prospective cohort study
Obstructive sleep apnea (OSA) is associated with hypertension (HTN), but the apnea–hypopnea index (AHI) and oxygen desaturation index (ODI) may not fully characterize nocturnal hypoxemia relevant to HTN development. We evaluated the associations of the sleep breathing impairment index (SBII) and hypoxic burden (HB)...
