Heart-Lung Bypass Units
Definition : Equipment that provide temporary external circulatory support to the cardio-pulmonary functions, by oxygenating the body's venous supply of blood and pumping it back into the arterial system; bypass units can perform circulation oxygenation, and filtration of the blood. These units are usually assembled in a console, which main components consist of an arterial pump, a backup arterial pump, one or two suction pumps, an arterial vent pump, a cardioplegia pump, and a backup unit; the console also includes some disposable components such as an oxygenator/heat exchanger, a cardiotomy reservoir, blood filters, and tubing. Heart-lung bypass units are mostly used during open heart surgery, bypassing the heart to facilitate surgery on the organ (e.g. , cardiac valve replacement, coronary artery bypass grafting); they are also used for extracorporeal membrane oxygenation in patients with severe respiratory disorders.
