Abstract

A cooling system is disclosed for cooling a person in a supine position as part of a clinical treatement. The system includes an air blower (10 or 98), a heat exchanger (7 or 100), an inflatable mattress (17) and a cooling jacket or overlay (11, 200). Air from the blower is cooled by contact with the heat exchanger, passed through the jacket or overlay and through the mattress in order to rapidly cool the person so as to achieve mild hypothermia.
