Effect of l-Arterenol Infusion on "Central Blood Volume" in the Dog

Abstract
Infusion of l-arterenol into anesthetized dogs increased the volume of blood in the heart and lungs, as indicated by an increase in "central blood volume," estimated lung volume and pressure changes in the heart and lungs. An analysis of pressure and flow data in the systemic venous bed during infusion of the drug suggests that important sources of the shifted blood are the peripheral veins and venules.
