Dependence of blood pressure changes in cats during acute hypoxic hypoxia on the type of carotid sinus reflex.
The type and degree of blood pressure changes in cats were studied in acute experiments under conditions of acute hypoxic hypoxia (40% decrease in oxygen partial pressure). During hypoxia, blood pressure increased in cats with pressor type of the carotid sinus reflex and decreased in animals with depressor type of this reflex. Our results indicate that the direction and degree of hypoxic changes in blood pressure in animals coincide with variations in this parameter in response to the carotid sinus reflex.
