What is the first step in controlling bleeding from a wound?

The first step in controlling bleeding from a wound is applying direct pressure on the wound. This method is essential because it helps to stop the flow of blood by compressing the blood vessels and encouraging clot formation. By applying firm and consistent pressure, you can significantly reduce or halt the bleeding, which is crucial in an emergency situation.

In most cases, direct pressure is prioritized over other methods due to its effectiveness and simplicity. Elevating the affected limb can be beneficial, particularly for bleeding from extremities, but it is most successful when combined with direct pressure. Tourniquet application is reserved for extreme cases where severe bleeding cannot be controlled with direct pressure, often involving significant injuries or if the bleeding is life-threatening. Cold compresses, while they might help with swelling and discomfort, do not effectively control bleeding and should not be the first response in such situations. Thus, direct pressure is the most immediate and effective action to take when managing a bleeding wound.
