What is the most common method to control external bleeding?

Direct pressure is the most common and effective method for controlling external bleeding. When direct pressure is applied to a bleeding wound, it helps to stem the flow of blood by compressing the blood vessels and allowing the body's natural clotting process to take over. This technique is usually the first step taken in both pre-hospital and hospital settings when addressing external bleeding, as it is simple to perform and widely applicable for various types of wounds.

Applying elevation of the limb can support blood flow reduction by gravity but is generally used in conjunction with direct pressure, rather than as a standalone method. Cold compresses can help manage swelling and may have a pain-relieving effect, but they are not primarily meant for stopping bleeding. While tourniquets are sometimes necessary for severe or life-threatening extremity hemorrhaging, they are typically considered a last resort and are used in situations where direct pressure fails to control the bleeding or when there is a risk of significant blood loss. Thus, direct pressure remains the go-to technique for managing most external bleeding incidents.
