O.3.3.3.1.4 There are three methods of rewarming the casualty: passive external rewarming, active external rewarming and active internal rewarming. For anything other than passive external rewarming for mild hypothermia, treatment should only be by a competent medical professional. However, for completeness, information on the other two methods of rewarming is included, see O.3.3.3.1.6 and O.3.3.3.1.7.O.3.3.3.1.5 Passive external rewarming is suitable for cases of mild hypothermia. It involves using body heat or ambient room temperature to aid the casualty’s body in rewarming itself. This includes moving to a warmer environment, the use of insulated dry clothing and wrapping in blankets or any other non-toxic insulating material available.
