The Rôle of the Chemoreceptors of the Sinus Region for the Occlusion Test in the Cat

Abstract

Summary. The effects of occlusion of the common carotids on the general blood pressure in anesthetized cats is decreased when oxygen is substituted for air, but increased if the arterial oxygen tension is decreased by ventilating with 7–10% oxygen in nitrogen instead of air. The blood pressure before occlusion is more or less influenced in the same direction.
