What should you do if a casualty is showing signs of shock?

When a casualty is showing signs of shock, laying them down and elevating their legs is a critical intervention. This position helps enhance blood flow back to the heart and vital organs by utilizing gravity to assist venous return. Elevating the legs can help counteract the effects of shock, which often involves a drop in blood pressure and decreased perfusion of tissues. This action supports the body's attempt to stabilize blood flow and maintain proper circulation.

In contrast, giving food and liquids immediately can be dangerous, especially if the casualty is unconscious or semi-conscious, as it poses a risk of choking. Keeping the casualty in a seated position is not advisable because it may further impede blood flow and exacerbate feelings of dizziness or weakness. Applying heat packs to warm the casualty could lead to complications, especially if the shock is due to a traumatic injury where internal bleeding might be a concern, as warming may worsen such bleeding.

Laying the casualty down with their legs elevated is a proven method in managing shock and is consistent with emergency medical practices, prioritizing stabilization until further medical care can be provided.
