Cheyne-Stokes Breathing after Denervation of Carotid and Aortic Chemoreceptors and Sino-Aortic Pressoreceptors. ∗

Abstract

Summary

Typical Cheyne-Stokes breathing has been observed in 2 dogs having the vagi sectioned bilaterally at the upper cervical level (denervating aortic bodies and aortic pressoreceptors) and having the carotid bodies and sinuses isolated or excised bilaterally. Therefore, neither oxygen-lack drive from chemoreceptors nor reflex effects on breathing from rhythmic fluctuations in pressure in the sino-aortic zones are concerned invariably in the production of Cheyne-Stokes breathing.
