Which techniques are effective for controlling bleeding?

The effectiveness of controlling bleeding is crucial in first aid, and the chosen techniques are essential in managing various types of bleeding situations. Direct pressure is the first and most effective method for controlling bleeding; it helps to clot the blood and minimizes blood loss. Elevation is another key technique; by raising the injured area above the level of the heart, it can reduce blood flow to the injury and slow down the bleeding. If the bleeding persists and is severe, a tourniquet may be necessary as a last resort to prevent excessive blood loss.

This combination of techniques is widely recognized in first aid protocols as an effective approach to managing bleeding, taking into consideration both immediate and potentially life-threatening scenarios. Other options may include less effective methods or combinations that do not align as well with established first aid practices, particularly in critical situations.
