In dealing with severe bleeding, what is the most important action to take?

Applying pressure to the wound is the most important action to take when dealing with severe bleeding because it directly helps to control the loss of blood. By applying consistent pressure, you support the body's natural coagulation process, helping to slow or stop the bleeding. This technique is effective for a variety of wounds and is a fundamental step in first aid management for severe bleeding.

While calling EMS is crucial, especially if the bleeding is severe and life-threatening, it is essential to apply pressure first to manage the immediate threat before additional help arrives. Raising the injured area above the heart can be beneficial in some cases, but it is often less effective than direct pressure in severe bleeding situations. Applying a tourniquet may be necessary for certain types of severe bleeding, particularly if the bleeding does not respond to pressure, but it is typically recommended after pressure techniques have been attempted. Thus, direct pressure to the wound serves as the primary and most critical immediate action.
