| Abstract: | Summary Cerebrovascular reactivity to CO2 (CO2R), measured in halothane-anesthetized rabbits, decreased as arterial pressure was increased either pharmacologically or mechanically. On the other hand, hypotension, induced by bleeding, led to an increase in CO2R. These responses were unaffected by denervation of baroreceptors.This work was supported by grants from NIH (HL 17903) and American Heart Association — Greater Los Angeles Affiliate (437IG).
