How should a medic respond to hypothermia in a casualty during TCCC?

The appropriate response to hypothermia in a casualty involves actions that help to preserve body heat and restore normal body temperature. Covering the casualty allows for the retention of their body heat, which is crucial in preventing further heat loss. Additionally, providing warm fluids, if the casualty is conscious and able to drink, can help to increase their internal body temperature. This method addresses both immediate symptoms and targets the underlying issue of hypothermia.

Utilizing a wet blanket would actually cause further heat loss, as the moisture would cool the body rather than warm it. Leaving a casualty exposed to air does not provide any benefits in terms of warming and can increase the risk of further hypothermia. Moving the casualty to a cooler area is counterproductive, as the priority in cases of hypothermia is to insulate and warm the individual, not expose them to more cold conditions.
