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. The high thermal conductivity and diffusivity of helium results in greater inspired gas temperature equalization toward body temperature. Due to the latent heat of vaporization, addition of even small quantity of phase-change perfluorocarbon dramatically increases the heat carrying capacity of the respiratory gases. Hypothermia may be terminated by discontinuing the medications and warming the patient using a warmed helium-oxygen mixture.

A method for treating cardiac failure such as congestive heart failure by application of hypothermia. Hypothermia may be applied by endovascular cooling using a heat exchange catheter circulating heat exchange fluid between an external heat exchanger controlled using temperature feedback from a temperature probe on or in the patient to cool the heart to a sufficiently low temperature for a sufficient length of time to increase cardiac output and improve the vascular condition of the patient. The patient may be maintained in the hypothermic condition for a period of time and is then re-warmed slowly and controllably. The endovascular temperature management may be controlled automatically in response to a temperature probe on the patient, and shivering while the patient is cool may be combated using surface warming and anti-shivering drugs. The method is applicable to treat congestive heart failure and may be used repeatedly on the same patient to restore that patient to adequate heart function when the vascular condition of that patient has become unacceptable. The method may be used to maintain a patient until a heart transplant becomes available. The method may be used to stabilize a patient's condition to allow needed surgery or intervention.
