Abstract

ObjectiveObstructive sleep apnea (OSA) is an independent risk factor for stroke. Little is known about the cerebrovascular hemodynamic changes during apnea. Hypercapnia occurs in apneas and hypopneas, and a reduced cerebral vasodilatory response to CO2 could compromise the cerebral blood flow (CBF). Therefore, we aimed to evaluate whether the apnea–hypopnea index (AHI) affected the cerebrovascular response to CO2.
