What is the primary method of controlling severe bleeding from an open wound?

Using direct pressure is the primary method of controlling severe bleeding from an open wound because it works by physically compressing the blood vessels at the site of the injury, thereby reducing blood flow and promoting clot formation. When direct pressure is applied firmly and consistently over the wound, it can help to stabilize the area and minimize blood loss. This technique is effective for most types of bleeding and is the first step recommended for managing wounds before any additional interventions are considered.

In situations of severe bleeding, the focus is on controlling the source of the bleeding as quickly as possible, and direct pressure provides a reliable and immediate measure for achieving this. If the bleeding does not stop with direct pressure, other techniques, such as elevating the limb or using a tourniquet, may be necessary.

Utilizing a cold compress does not directly address the source of bleeding and may only provide temporary relief in terms of swelling rather than effectively controlling blood loss. Elevating the limb can help reduce blood flow to the area but is generally not as effective as direct pressure alone. A tourniquet may be appropriate in certain circumstances, particularly in the case of life-threatening extremity bleeding, but it is usually considered a secondary option after direct pressure has been attempted. Thus, direct pressure remains the
