In Tactical Field Care, how should a casualty experiencing severe hypothermia be treated?

In cases of severe hypothermia, gradual warming is crucial to avoid potential complications. Rapid warming can lead to a dangerous condition known as "rewarming shock," where the sudden influx of warmer blood from the core to the extremities can cause cardiovascular issues and result in further complications, such as arrhythmias.

When warming a hypothermic casualty, it's important to apply warming methods such as insulating them with blankets, using warm packs, or other controlled warming techniques, while avoiding submersion in hot water and exposure to cool air. These approaches help to stabilize the patient's condition without inducing shocks to their system.

Therefore, treating the casualty with careful and slow warming methods ensures both safety and effectiveness, making gradual warming the preferred approach in managing severe hypothermia during Tactical Field Care.
