Abstract

Regional cerebral blood flow measurements have been made at two levels of Pa CO 2 , using the clearance of 133 Xenon injected into the internal carotid artery. Specific and percent changes in blood flow per mm Hg change in Pa CO 2 . (CO 2 reactivity) have been calculated for the fast and slow clearing tissue (Ff and Fs) and F initial. Mean hemisphere CO 2 reactivity was marginally greater in the fast clearing tissue than in the slow clearing tissue (P = 0.05). On a regional basis the greater CO 2 , reactivity of Ff over Fs was significant in five areas (P ≤ 0.05). A strong positive linear correlation between mean specific reactivity and conductance (the reciprocal of resistance) has been demonstrated for Ff and Fs and confirmed in the F initial.
