Perfusionists are members of cardiovascular surgical teams. They are responsible for the operation of heart-lung machines and other cardiovascular devices that are connected to patients during open-heart surgery and other procedures. During surgeries in which a patient’s heart must be stopped, a perfusionist utilizes the heart-lung machine to oxygenate the blood and return it to the body’s tissues while bypassing the heart and lungs. In addition to operating rooms and surgical centers, perfusionists may provide assistance in cardiac intensive care units. Perfusionists also administer medications that allow a patient’s heart function to cease during surgery.
