What is the first step in controlling bleeding from a large wound in the leg?

Applying direct pressure with a gauze pad is the first and most crucial step in controlling bleeding from a large wound in the leg. This method works by compressing the blood vessels in the area, which helps to staunch the flow of blood. Direct pressure is the most effective way to address immediate bleeding, especially in a scenario where significant blood loss can occur rapidly.

Immediately applying pressure can help prevent the situation from worsening and allows time for further care to be administered if necessary. Other methods, such as elevating the leg, can be beneficial but should be secondary to the primary need to control bleeding. Cleaning the wound and wrapping it with elastic bandages are also important steps in a complete treatment plan, but they should only be approached after controlling the bleeding has been established to avoid disrupting the clotting process.
