In the early years of clinical heart-lung bypass, blood-warming devices were used to maintain the patient’s normal (37°C) temperature during cardiopulmonary bypass (CPB). The development of hypothermic CPB techniques led to the development of heat-exchange devices for the extracorporeal circuit that are capable of rapidly warming or cooling blood.
