The Effects of Progressive General Anoxia on the Pulmonary Circulation

Abstract

The effects of progressive anoxia on the hemodynamic changes in the pulmonary circuit were reinvestigated in anesthetized dogs. Evidence is presented that some increase in pulmonary arterial resistance takes place, but that the augmented output of the right ventricle is dominantly responsible for elevation of the pulmonary arterial pressure when anoxia affects the body as a whole.
