[Hering-Breuer inhibitory reflex in cats with hypoxia and following carotid sinus denervation].
In decerebrated and anesthetized vagotomized cats, the effects of hypoxia and carotid sinus denervation on the Breuer--Hering reflex, induced by inflation of the lungs or stimulation of the central end of vagus nerve were studied. Hypoxia was followed by shortening of reflex inhibition of inspiration elicited both by inflation of the lungs and afferent vagus fibers stimulation. After carotid sinus denervation the effect of hypoxia on the Breuer--Hering reflex was almost completely abolished, and a reduction of the overall ventilation response (VTXf) during hypoxia occurred.
