What should combat lifesavers do if they suspect a fracture?

Stabilizing the fracture site, usually with a splint, is the appropriate action for combat lifesavers when they suspect a fracture. This step is crucial because immobilizing the injured area helps to prevent further injury or damage to the surrounding tissues, blood vessels, and nerves. It also alleviates pain and reduces the potential for complications, such as blood loss or shock, which can exacerbate the casualty's condition.

When applying a splint, it's important to ensure that it is done properly to maintain alignment and support the affected limb. This can be achieved using available materials, making the process adaptable in a tactical environment.

While other methods like transporting the casualty, encouraging movement, or using ice may be useful in certain situations, they are not the immediate priorities when a fracture is suspected. Transporting someone without stabilizing the fracture could lead to increased pain or further injury. Encouraging movement could worsen their condition, and while ice might help with swelling, it's not a primary intervention in the acute phase of a suspected fracture. Therefore, adequately stabilizing the injury is essential for appropriate care.
