Analysis of Heat Exchange during Cooling and Rewarming in Cardiopulmonary Bypass Procedures
For over two decades, whole-body hypothermia has been widely used to reduce metabolic demand and protect vital organs during cardiopulmonary bypass (CPB) for open heart surgery. Some form of hypothermia is currently being used in over 85% of the 275,000 CPB procedures performed annually in the world today. This procedure is among the most widely used and least quantified, from a modern engineering standpoint, of all modern medical uses of hypothermia.
