The researchers are trying to reduce the need for blood transfusions in subjects having surgery that will involve the use of cardiopulmonary bypass. A unit of whole blood will be removed as part of their standard of care prior to going on cardiopulmonary bypass (CPB). This unit is given back to the subject post CPB. This has been shown to reduce the need for blood transfusion in patients.
