1. A portable microclimate and life-support system for care of a patient, comprising:

  • a portable housing that houses therein (i) a heat exchanger configured to regulate the temperature of a thermal fluid, wherein the heat exchanger has a thermal fluid outlet port and a thermal fluid return port, and (ii) an oxygen source;

    a body covering configured to be placed in covering contact with the patient having one or more thermal fluid passages to regulate the temperature of the patient in thermal contact with the body covering;

    a thermal conduit in fluid communication with the one or more thermal fluid passages of the body covering, the thermal conduit having a thermal fluid supply tube in fluid communication with the thermal fluid outlet port and a thermal fluid return tube in fluid communication with the thermal fluid inlet port, wherein the thermal conduit forms a closed fluid loop configured to deliver thermal fluid from the heat exchanger to the one or more thermal fluid passages and returning thermal fluid from the one or more thermal fluid passages; and

    an oxygen delivery interface; and

    an oxygen delivery conduit having an oxygen heating source in thermal communication with at least a part of the length of the oxygen delivery conduit, the oxygen heating source is configured to deliver sufficient heat to the oxygen in the oxygen delivery conduit to heat the temperature of oxygen to a temperature above the ambient temperature, wherein the oxygen delivery conduit is in fluid communication with the oxygen delivery source and is configured to deliver oxygen from the oxygen delivery source to the oxygen delivery interface.
