If you apply a hasty tourniquet and find it ineffective during a blood sweep, what should you do?

Applying a deliberate tourniquet after finding that a hasty tourniquet is ineffective is the most appropriate action in this scenario. This approach allows for the proper application of a tourniquet that is designed for sustained use, which can effectively control blood loss. Deliberate tourniquets are typically more robust and better constructed than hasty ones, providing a more reliable means of occlusion.

While removing the hasty tourniquet at this point might seem tempting, it is crucial to maintain pressure on the affected area to prevent further blood loss. By slowly removing the hasty tourniquet while applying a deliberate one, you ensure that blood flow is controlled throughout the process. This careful transition minimizes the risk of re-exposing the injury to bleeding, ensuring that the patient's condition is stabilized.

Using direct pressure on the wound could also be an effective method in certain situations, but if a tourniquet has already been applied, the focus should remain on the need for effective hemorrhage control methods. This makes the application of a deliberate tourniquet the best course of action in managing severe bleeding effectively.
