ABSTRACT:
A system for automatically controlling the amount of heat delivered to a human body through ventilator therapy so as to maintain the body at a desired core temperature. The temperature of the inspired and expired gas is measured by temperature sensors to control operation of an inhalation heater so that the inspired gas temperature tracks the expired gas temperature with different adjusted separations. Automatic switching is under control of a body core temperature sensor detecting deviations from the desired body temperature.
