O.3.3.3.1.6 Active external rewarming, which is suitable for moderate cases of hypothermia, involves applying warming devices externally, such as a heating blanket, a warm water bottle placed on the chest, neck, under the arms or in the groin or a warm water bath, all which should be within the temperature range 38 °C to 42 °C (100 °F to 108 °F) but see O.3.3.3.3.2.O.3.3.3.1.7 Active internal rewarming is sometimes used in cases of severe hypothermia. Active internal warming is hazardous and should only be done in hospital. The process involves procedures such as intravenously applied warmed fluids; irrigation of body cavities with warmed fluids; inhalation of warm, humidified air; extracorporeal rewarming, which means the blood is warmed outside the body before being returned to it. Extracorporeal rewarming is the fastest method for those with severe hypothermia.O.3.3.3.2 Caring for a casualty while awaiting professional medical help
