What is the first step in controlling bleeding?

Applying direct pressure is the first step in controlling bleeding because it helps to stem the flow of blood from a wound. When direct pressure is exerted on an area of bleeding, it encourages the blood vessels to constrict and can promote the formation of a clot, thereby minimizing blood loss. This method is straightforward and can be applied immediately by anyone witnessing the injury, making it a crucial skill in first aid.

Other options serve supportive roles in controlling bleeding. Elevation (applying elevation) can help reduce blood flow to the injury site, but it is most effective when combined with direct pressure. A pressure bandage is used after direct pressure is already applied, to keep the pressure in place and help maintain clotting. Seeking professional medical assistance is vital, particularly for severe injuries, but it is not the first immediate step in managing bleeding. The priority is always to control the bleeding first through direct pressure.
