Cerebrovascular Response to CO2 Following 10 Days of Intermittent Hypoxia in Humans.
It has been demonstrated that the cerebrovascular response to hypoxia is blunted following 10 d of intermittent hypoxia (IH) in healthy humans. The purpose of this study was to test the hypothesis that IH reduces the cerebrovascular response to CO2. ⋯ Our data indicates that 10 d of IH in healthy humans does not alter the cerebrovascular response to CO2. Redundancy of cerebrovascular regulation mechanisms to CO2 may work to counteract IH-induced dysregulation and protect cerebral tissue.
