What is the preferred technique for controlling severe bleeding?

Direct pressure on the wound is the preferred technique for controlling severe bleeding because it effectively promotes clotting and minimizes blood loss. When direct pressure is applied, it compresses the blood vessels and surrounding tissue, which helps to slow down or stop the bleeding. This method allows the body's natural clotting mechanisms to start working and is typically the first step in first aid for severe bleeding.

In addition, applying pressure can be easily done with any available clean cloth or bandage, making it a practical approach in an emergency situation. If the bleeding is especially severe and does not stop with direct pressure alone, elevating the injured area can further help by reducing blood flow to the wound. However, direct pressure remains the priority in immediate care.

Utilizing a tourniquet is reserved for situations where the bleeding is life-threatening and direct pressure fails to control it, making that a more advanced intervention. Similarly, using ice may help reduce swelling or numb the area, but it does not actively address severe bleeding in the same direct manner as applying pressure does.
