THE EFFECT OF THE FORMATION OF AN ARTERIOVENOUS FISTULA UPON BLOOD VOLUME 1

Abstract
Blood volume was measured in 7 dogs, using P32-tagged red cells and T-1824, before and up to 6 weeks after a large fistula was created between the aorta and inferior vena cava. The following were noted: (1) No change in total red cell volume. (2) An expanded plasma volume, reflected in a lowered hematocrit and an increase in the volume of distribution of T-1824. (3) A decrease in the ratio of total body hematocrit of arterial blood.
