Devices and methods to heat and cool human beings, including inducing and maintaining hypothermia in human patients. Methods include inducing hypothermia to treat ischemic events, including heart attack and stroke, to limit damage caused by the ischemic event. Methods can include: using the lungs for heat exchange; using cooled gases for ventilation; using helium in the ventilation gas mixture, using medications to control reflex heat production; and injecting a perfluorocarbon mist into the gas stream to increase the cooling rate.
