Venous Pressure and Total Peripheral Resistance in the Dog

¹ From the Departments of Surgery and Physiology, University of Minnesota Medical School, Minneapolis, Minnesota

The techniques of total body perfusion have been applied to the problem of the influence of venous distension on resistance to blood flow. The results obtained support the classical view that a rise in venous pressure leads to a fall in total peripheral resistance. The possibility of a venivasomotor constrictor reflex occurring in certain parts of the circulation was not excluded by these studies.
