What should be the first step in attempting to stop bleeding?

The first step in attempting to stop bleeding should be to apply direct pressure to the wound. This is important because direct pressure helps to control the bleeding effectively by compressing the blood vessels and encouraging clotting at the sight of the injury. When pressure is applied, it can significantly reduce blood flow to the area and is often sufficient to manage minor to moderate bleeding.

While a tourniquet can be effective for severe bleeding, it is generally used as a last resort when direct pressure fails, and it is reserved for situations like traumatic injuries to limbs where bleeding cannot be controlled by other means. Bandages are also important for securing dressings in place after pressure is applied, but they do not serve as an immediate means to control bleeding. Administering oxygen is crucial for patient care in certain medical emergencies, but it does not assist in stopping the bleeding itself. Hence, applying direct pressure is the most critical and immediate action in any bleeding situation.
