Which method is considered a last resort for controlling severe bleeding?

The use of a tourniquet is recognized as a last resort for controlling severe bleeding because it is an intervention that carries significant risks if not applied correctly. Tourniquets can effectively stop arterial blood flow to a limb when bleeding is life-threatening and other methods, such as direct pressure and elevation, have failed.

Using a tourniquet puts immense pressure on the blood vessels, which can damage the tissue if applied for an extended duration or if not necessary. Therefore, it is essential to reserve this method for situations where the person is at risk of exsanguination and rapid intervention is critical.

Direct pressure and elevation are more commonly used first because they are less invasive and have fewer complications. Pressure points can also be utilized to help control bleeding but are typically less effective than the direct application of a tourniquet. This hierarchical approach ensures that the most appropriate methods are used first, minimizing harm while effectively managing severe hemorrhaging.
