If a person is bleeding heavily, which is the most effective initial treatment?

Applying direct pressure to the wound is the most effective initial treatment for heavy bleeding. This method works by directly compressing the blood vessels at the site of the injury, which helps to slow down or halt the flow of blood. By applying consistent, firm pressure, the body has a better chance of forming a clot, which is crucial for stopping the bleeding effectively.

While keeping the person calm and comfortable, elevating their legs, and loosening any restrictive clothing are all supportive measures that can be beneficial in certain situations, they do not directly address the immediate need to control heavy bleeding. Direct pressure is the priority in managing a bleed to prevent further blood loss and complications.
