Extracorporeal heat exchanger

Piepgras A., Roth H., Schurer L., et al. (1998) Rapid active internal core cooling for induction of moderate hypothermia in head injury by use of an extracorporeal heat exchanger. Neurosurgery 42, 311-317 discussion 317-318. 

The presence of an extracorporeal bypass circuit results in large heat losses from the blood. Thus an integral heat exchanger is essential to regulate the patient s body temperature. To decrease the oxygen demand during surgery, the patient s body temperature is often maintained at 5°C-10°C below normal body temperature.
