Abstract
A device consisting of a teflon arterial graft connecting pulmonary artery and left auricle and containing within its lumen coils of silicone rubber capillary tubing bearing a flow of oxygen was used as a method for artificial intracorporeal oxygenation. In 7 to 10 experiments, using dogs and sheep, a definite influence upon systemic arterial oxygen tensions was demonstrated. A problem of blood clotting within the lung prosthesis was encountered in 3 experiments due to kinking of the graft, tightly packed capillary tubing, and failure to maintain anti-coagulation.
