1. A perfusion hyper/hypothermia treatment system comprising:

  • a computer system;

    a source of physiological fluid having a temperature;

    an interface coupled to receive a plurality of temperature signals from temperature sensors, the interface coupled to the computer system, the temperature signals representative of temperatures at each of a plurality of patient locations on or within a patient;

    a converter coupled to the interface, and that generates at least one temperature value representative of at least one of the temperatures;

    a comparator coupled to receive the temperature value and to receive a set of stored parameters in the computer system, and to generate a comparison value;

    a heat exchanger the source of physiological fluid;

    a signal generator coupled to the computer system which generates a control signal that is coupled to the heat exchanger to control a change in the temperature of the physiological fluid based on the comparison value; and

    a perfusion mechanism, in fluid communication with the heat exchanger, that receives the physiological fluid after a temperature change has been affected and perfuses the physiological fluid into the patient.
