In eight rabbits, the common carotid artery was ligated and multiple
estimations of brain surface oxygen tension performed using a seven
barrelled mini-electrode. In five rabbits ligation of the carotid artery
resulted in impairment of cortical oxygenation. The remaining three rabbits
showed no impairment in the supply of oxygen to the cerebral cortex after
carotid occlusion. In the five rabbits who displayed a reduction in oxygen
supply after carotid ligation, ventilation with 33% oxygen after the
infusion of 15 ml/kg of Fluosol FC-43 produced an improvement in cortical
oxygenation in only three of the five rabbits. When these animals were
ventilated with 100% oxygen after carotid ligation and Fluosol infusion,
oxygen supply in all five was commensurate with or greater than that during
control conditions.
