What is the role of direct pressure in managing external bleeding?

The primary role of direct pressure in managing external bleeding is to stop the bleeding. When direct pressure is applied to a bleeding wound, it compresses the blood vessels and helps to promote clotting by encouraging the formation of a thrombus at the injury site. This method is a fundamental first-aid technique and is typically the first step taken in bleeding control. By applying consistent pressure, you restrict blood flow and minimize blood loss, which is critical in preventing shock and stabilizing the victim until further medical help can be provided.

While reducing pain, protecting the wound, and lowering the risk of infection are important considerations in wound care, they are secondary to the immediate need to control bleeding. Pain management might come after bleeding is addressed, protection and infection control are essential for healing but do not directly impact the immediate need to stop active bleeding. Understanding that the central aim of direct pressure is to control hemorrhage is crucial for effective emergency response.
