description Forest Dodrill Overview
Forest Dewey Dodrill was an American cardiac surgeon known for early work with mechanical support during heart operations. In 1952, working with engineers from General Motors, he used the Dodrill-GMR mechanical heart pump during surgery on a human patient. The device temporarily supported circulation and formed part of the experimental work that preceded the routine clinical adoption of cardiopulmonary bypass.
help Forest Dodrill FAQ
What was the Dodrill-GMR heart machine?
It was a mechanical pump developed by Forest Dodrill with engineers from General Motors Research. The machine could temporarily take over part of the heart's pumping work during surgery.
When was the Dodrill-GMR machine first used on a patient?
Dodrill used it during a human heart operation in 1952. The procedure was performed at Harper Hospital in Detroit.
Was the Dodrill-GMR machine a full heart-lung machine?
No. It initially functioned as a mechanical heart pump and did not itself oxygenate blood in the same way as a complete cardiopulmonary bypass system.
Why did General Motors help Forest Dodrill build a surgical machine?
General Motors engineers contributed expertise in pumps, mechanics and precision engineering. Their collaboration with Dodrill produced a device designed to reproduce the heart's pulsatile pumping action.
