To help control severe bleeding effectively, which of these is usually done last?

Using a tourniquet is typically considered a last resort in controlling severe bleeding because it is an invasive method that can cause significant complications if used improperly. Tourniquets are designed to compress blood vessels and restrict blood flow to a limb, effectively stopping arterial bleeding in extreme cases. However, their application carries risks, such as potential damage to nerves and tissue, making it crucial to use them only when other methods have failed or are not sufficient.

By contrast, techniques such as applying direct pressure, elevating the injury site, or using pressure points are generally less invasive and more appropriate as initial responses to severe bleeding. These methods allow for quicker application and have a lower risk of serious complications. Therefore, the use of a tourniquet is reserved for situations where these first-line methods do not yield results, highlighting its position as a final measure in controlling severe bleeding.
