Attempts have been made to support the circulation in myocardial infarction1 and congestive heart failure2 by diverting part of the venous return from the heart and pumping it into the aorta. We have previously reported a closed system * for withdrawing about half the venous return from the superior cava and pumping it without oxygenation into the lower aorta.3-5 This paper is concerned with the effects of venoarterial pumping on the circulation and metabolic state.

Methods  A Bardic cannula (No. 17 to No. 22) was inserted in the right external jugular vein of the subject dog, its tip reaching the junction of the innominate veins, and a similar cannula (No. 12 to No. 18) was placed in a femoral artery. Nylon adapters connect the cannulae to Tygon tubing of 3/8-in. (1 cm.) internal diameter which is used throughout the system. Two nylon adapters with side-arm stopcocks allow sampling,
