Rapid induction of mild hypothermia

A system comprising:

• a headgear for contacting at least a portion of a head of a patient;
• a body gear for contacting at least a portion of a body part of the patient other than the head;
• and
• a coolant supply container for supplying coolant to the headgear and the body gear.

A method comprising:

• separating at least a portion of a cooling garment from a body of a patient to create a space;
• allowing a coolant to exit a coolant delivery conduit onto the body in the space;
• allowing a carrier gas to enter the space via a carrier gas port;
• and
• expelling the coolant in a gaseous state from an exit port in the garment.

A device comprising:

• an inner shell proximate to a body part of a patient, a space between the body part and the inner shell being an inner space;
• an outer shell surrounding the inner shell, a space between the outer shell and the inner shell being an outer space in fluid communication with the inner space;
• and
• an exit port for expelling a coolant and a gas, the gas moving from the outer space to the inner space.
