What is direct pressure and when should it be used?

Direct pressure refers to the application of pressure directly over a bleeding site to control hemorrhage. It is an essential immediate response to bleeding and should be used as the first line of intervention when managing traumatic wounds. The application of direct pressure serves to compress the blood vessels and tissues at the site of the injury, thereby reducing blood flow and promoting clotting.

Using direct pressure is particularly important in situations where a tourniquet or more advanced dressings are not immediately available or appropriate. It is a critical skill for combat medics and corpsmen to master, as prompt control of bleeding can significantly affect the casualty's chance of survival.

In contrast, the other responses do not accurately describe the purpose or application of direct pressure. For instance, applying pressure to the back does not address the site of bleeding, and pressure applied before assessing the wound can lead to missed assessments critical for appropriate treatment. Likewise, applying pressure on the opposite side of the wound may not effectively control bleeding, as it does not target the source of hemorrhage directly. Therefore, understanding when and how to use direct pressure is vital in bleeding management within the context of Tactical Combat Casualty Care.
