What is the technique to control severe bleeding?

Applying direct pressure to the wound is the most effective initial technique for controlling severe bleeding. This method works by compressing the blood vessels that are open, which helps to stop the flow of blood. It is essential to maintain firm and consistent pressure directly on the site of the bleeding, as this can significantly reduce blood loss and stabilize the injury until further medical help can be obtained.

While other techniques, such as elevating the injured limb above the heart or using a tourniquet, are also valid approaches under certain circumstances, they are typically used in specific scenarios when direct pressure is ineffective or the bleeding is particularly severe and life-threatening. Soaking a wound with cold water does not provide any real benefit for controlling bleeding and can potentially introduce contaminants, which may complicate the injury. Thus, direct pressure remains the primary method for managing severe bleeding effectively.
