What is the most effective way to control severe external bleeding?

Applying direct pressure on the wound is the most effective immediate measure to control severe external bleeding. This technique works by physically compressing the blood vessels at the site of the injury, which reduces blood flow and encourages clot formation. By applying firm and consistent pressure directly on the wound, you help to minimize blood loss until further medical assistance can be provided.

In emergency situations, it is essential to act quickly, and direct pressure is typically the first step recommended by medical guidelines. This method is simple to perform and does not require special equipment, making it accessible in various environments where injuries may occur.

Other options, while potentially helpful in specific circumstances, do not provide the same level of immediate effectiveness as direct pressure. For instance, applying a tourniquet is reserved for severe, life-threatening bleeding where direct pressure is not sufficient or where a limb needs to be controlled. Elevating the bleeding limb can assist in reducing blood flow to some extent but is not as effective as direct pressure. Similarly, applying ice can help with swelling and pain but does not effectively halt bleeding. Therefore, for immediate bleeding control, applying direct pressure remains the most reliable method.
