Which step is NOT part of the first aid response to a bleeding wound?

Using heat to encourage clotting is not a recognized step in the first aid response to a bleeding wound. In fact, applying heat directly to a bleeding area could potentially worsen bleeding or cause more damage to the tissue. The appropriate actions include applying pressure to the wound, which is crucial for controlling bleeding. Elevating the wound above the level of the heart can help reduce blood flow to the area and assist in clotting. Finally, seeking medical help is essential if the bleeding is severe or does not stop with initial first aid measures. These steps are fundamental to managing bleeding effectively and ensuring the safety and health of the injured person.
