Abstract
A system for regulating a core body temperature of a person includes a pressure applicator configured to apply negative or cyclical positive pressure to a portion of the person to vasodilate blood vessels of the person within the portion, a heating device configured to supply heat to the portion of the person, and a control apparatus. The control apparatus is coupled to the heating device and includes a controller configured to vary the amount of heat supplied by the heating device. The amount of heat supplied by the heating device is varied in response to a difference in temperature between a preset temperature programmed into the controller and an actual core body temperature of the patient received by the controller from a temperature sensor on the person such that the controller maintains the actual core body temperature of the person at substantially the preset temperature.
