In general, the disclosure presents techniques for rapidly cooling the body of a patient. A cooling garment is placed in contact with the body of the patient. Spacers within the cooling garment create a space between at least a portion of the cooling garment and the body of the patient. The cooling garment receives a coolant from a coolant supply and delivers the coolant to the body of the patient. The heat from the body of the patient may evaporate the coolant. A carrier gas, which circulates within the space between the cooling garment and the patient, carries the gaseous coolant out of the cooling garment via an exit port. The rapid cooling of the patient may slow the neurological damage to the patient.

Rapid induction of mild hypothermia

The invention is directed to techniques and apparatus for controlling the temperature of a coolant delivered to a patient in a hypothermic therapy system, including a hypothermic therapy system that can be applied to a patient outside or inside a hospital setting. In general, the coolant is in a pressurized form at ambient temperature, and is expanded proximate to the patient to cause the coolant to cool. Cooling garments placed in contact with the body of the patient circulate the cooled coolant proximate to the patient to cool the patient. A controller controls the temperature of the coolant by mixing the coolant with ambient air, for example, to reduce the risk of harm the patient.
