Abstract: Cardiovascular parameters of a patient undergoing a procedure involving general anesthesia are maintained by controlling the patient's body temperature. Such control involves the use of a garment enveloping substantial portions of the patient's body and utilizing a heating/cooling regime taking into consideration the heat transfer dynamics of the body.

Abstract: A heat exchanger for use in controlling subject's body temperature during a medical procedure comprises a flexible garment adapted for enveloping portions of the subject's body surface with dedicated sections for enveloping different body parts. Defined within the garment is a continuous, fluid tight space, wherein a flow path for heat-control fluid is defined between fluid inlet and fluid outlet. The inner faces of the garment's internal and external layers are made of a heat-weldable material and are point-welded to one another at a plurality of locations throughout the garment with a distance between two adjacent points being between about 8 to about 20 mm.
