1. A system comprising:
an inspiration chamber having an inspiration chamber top and an inspiration chamber bottom;
an inspiration chamber inlet for receiving gas into the inspiration chamber;
an inspiration chamber outlet for expelling the gas from the inspiration chamber at a pressure of between one-hundred-and-twenty centimeters of water (120 cmH2O) and three-hundred centimeters of water (300 cmH2O);
an expiration chamber having an expiration chamber top and an expiration chamber bottom, the expiration chamber top aligning with the inspiration chamber top, the expiration chamber bottom aligning with the inspiration chamber bottom;
an expiration chamber inlet for receiving expired gas at a pressure of between negative fifty centimeters of water (−50 cmH2O) and zero centimeters of water (0 cmH2O);
an expiration chamber outlet for expelling the expired gas;
a subject conduit for receiving the gas from the inspiration chamber and providing the gas to a subject at a pressure of between 120 cmH2O and 300 cmH2O, the subject conduit further for receiving the expired gas from the subject at a pressure of between −50 cmH2O and 0 cmH2O and providing the expired gas to the expiration chamber;
a valve operatively coupled to the inspiration chamber outlet, the valve further being operatively coupled to the expiration chamber inlet, the valve for selectively opening the inspiration chamber outlet and closing the expiration chamber inlet when positive pressure from the inspiration chamber is applied to the valve, the valve further for selectively closing the inspiration chamber outlet and opening the expiration chamber inlet when no positive pressure is applied to the valve from the inspiration chamber; wherein: the inspiration chamber comprises an inspiration chamber pressure release valve for opening when the pressure in the inspiration chamber is higher than a predefined threshold maximum positive pressure; the gas in the inspiration chamber is at a temperature that is sufficient to induce therapeutic hypothermia; the predefined threshold maximum positive pressure higher than 300 centimeters of water (300 cmH2O); and the expiration chamber comprises an expiration chamber pressure release valve for opening when the pressure in the expiration chamber is lower than −50 cm H2O.
