Differential cerebrovascular CO2 reactivity in anterior and posterior cerebral circulations

• Cerebrovascular reactivity between anterior and posterior circulations was compared. • TCD and hyperoxic rebreathing were used to test cerebrovascular reactivity. • The PCA can be used as a surrogate for BA measures of CO2 reactivity. • The absolute CO2 reactivity is larger in the MCA compared to...
