What is the first step in preventing shock in a casualty?

The first step in preventing shock in a casualty involves positioning the casualty appropriately. This is crucial because the right position can help improve blood circulation and support vital organs while reducing the risk of shock. Typically, positioning the casualty on their back with their legs elevated can facilitate blood flow back to the heart and brain, especially if they are conscious and do not have any imminent injuries that would prevent this position.

While notifying medics, reassuring the casualty, and elevating the legs are important actions, they usually follow the initial step of properly positioning the individual. Each of these subsequent actions supports the overall effort to stabilize the casualty and maintain their wellbeing, but securing a proper position first establishes a foundation for other interventions. Therefore, correct positioning is essential in the early stages of managing shock in an injured person.
