Why is it critical to apply direct pressure to a bleeding wound?

Applying direct pressure to a bleeding wound is crucial because it helps to stop the bleeding by promoting clotting at the site of the injury. When pressure is exerted on a wound, it compresses the blood vessels, which can significantly reduce blood flow and facilitate the formation of a clot. This is especially important in cases of hemorrhage, where excessive blood loss can lead to shock or even death in a short period. The application of direct pressure is a fundamental first-aid technique that can stabilize a casualty until more advanced medical help is available.

While preventing infection, reducing pain, and keeping the area warm are important aspects of wound care and first aid, they are not the primary reason for applying direct pressure. The immediate goal in the context of a bleeding wound is to control the hemorrhage effectively.
