What is the protocol if the casualty displays signs of shock?

When a casualty displays signs of shock, the primary concern is to maintain blood flow to vital organs. Keeping the casualty warm and elevating their legs aids in promoting venous return to the heart, which can help improve circulation and maintain perfusion to essential organs. This position allows gravity to assist the blood flow back towards the heart, increasing the volume of blood available for vital functions, and warming the casualty helps prevent further deterioration by mitigating hypothermia, which can exacerbate shock.

While administering IV fluids could be beneficial, it should not always be the first step taken or initiated outside of a controlled medical environment. Elevating the legs and maintaining warmth are immediate actionable steps that can be taken in the field.

Keeping the casualty sitting up is inappropriate since this position could compromise blood flow and may worsen their condition. Similarly, doing nothing until transported can lead to further complications or death; prompt intervention at the scene is crucial in managing shock effectively.
