METHODS AND DEVICES FOR PREVENTION OF HYPOTHERMIA IN A MAMMAL DURING PROLONGED EXPOSURE TO EXTREME COLD

摘要

Methods and devices for preventing a change in the core body temperature of a mammal under cold conditions are provided. In the subject methods, a requirement for thermal energy input in said mammal is first detected. In response to the detection of this requirement for thermal energy input, a surface of a portion of the mammal is contacted with a warm temperature medi um under negative pressure conditions for a period of time sufficient to introduce thermal energy into the core body of the mammal. The subject devic es include at least a means for detecting a requirement for thermal energy inpu t and a means for contacting a surface of a mammal with a warm temperature medium under negative pressure conditions (104). The subject methods and devices find use in a variety of applications, and are particularly suited f or use in maintaining the core body temperature of a mammal substantially under cold conditions for an extended period of time.
