Summary
A study was made in cats of the effect on respiration under an oxygen partial pressure raised to 30 mm Hg of occlusion of the common carotid arteries and of denervation of the carotid sinus.
Occlusion of the common carotid arteries caused complete cessation of respiration when the oxygen partial pressure was raised, whereas denervation of the carotid sinus caused respiration to increase.
When oxygen partial pressure was increased neither occlusion of the common carotid arteries nor denervation of the carotid sinus significantly affected the time of respiratory arrest.
We concluded that the reflexes originating in the carotid sinus activated respiration under conditions of raised intrapulmonary partial pressure.
