Beschreibung
Zusammenfassung:	A system for controlling patient temperature uses a central venous line catheter (20) having a heat exchange element (24). The central venous line catheter (20) is provided with one or more lumens for providing access to the central blood supply of the patient, and with additional lumens for communicating heat exchange fluid to the heat exchange element (24). Heat exchange fluid temperature is controlled through a feed back loop in which patient temperature is sensed, used to control a temperature control unit comprising a heating device, and/or cooling device in heat exchange relationship with the heat exchange fluid. A tubing set transports the heat exchange fluid between the central venous line (20), and the temperature control unit, with a pump serving to circulate the fluid in a closed fluid circuit in the system.
