Heat should be applied. This may require that one member of the party build a fire or start a stove and heat water, coffee, or tea; hot-water bottles may be improvised from canteens or extra fuel cans. Avoid overheating the patient until he perspires. Although such a condition can hardly be attained outside in the snow, room temperature, blankets, and hot-water bottles may cause the patient to perspire after he has been brought indoors. He is then subject to being chilled later; moreover, the blood is brought to the skin and thereby is lost to the general circulation and to more important organs, where it is badly needed. |
