When applying the emergency bandage to head what do you prevent from shifting?

When applying an emergency bandage to the head, the primary goal is to prevent the scalp from shifting. The scalp is highly vascularized, meaning it contains a lot of blood vessels, and if it shifts, it can cause severe bleeding. To prevent this, the bandage should be applied tightly and evenly around the head, ensuring that it covers the entire area of the injury. Additionally, the bandage should be secured in place with adhesive tape or other suitable materials to prevent it from slipping or coming loose.
