What does direct pressure refer to in first aid?

Direct pressure refers specifically to applying pressure immediately onto a wound in order to control bleeding. This is a fundamental practice in first aid, as it helps to stanch blood flow and promote clotting by applying a force directly where the bleeding is occurring.

When applied correctly, direct pressure can be highly effective in managing external bleeding and is often the first step taken in wound care. It's important to use a clean cloth or dressing to avoid introducing bacteria into a wound.

While other options may be related to managing bleeding, they do not define direct pressure. For example, using gauze on a wound involves placing material over the wound but does not explicitly indicate the immediate application of force, which is essential for controlling bleeding. Similarly, applying a tourniquet is a more advanced technique used in severe situations and is not considered direct pressure. Finally, elevating a wound above heart level is an additional first aid measure that can aid in reducing blood flow to the area but does not substitute the need for direct pressure when there is significant bleeding.
