What is considered the last resort to stop severe bleeding?

A tourniquet is considered the last resort to stop severe bleeding because it is a technique used when other methods, such as applying direct pressure or using a sterile dressing, have failed or are deemed insufficient. The application of a tourniquet can effectively reduce blood flow to the affected area by compressing the blood vessels tightly, thereby preventing further blood loss.

Using a tourniquet is typically reserved for life-threatening situations where limb hemorrhage cannot be controlled through less invasive measures. It's critical that a tourniquet is applied properly and only when absolutely necessary, as there can be significant risks associated with its use, including potential limb loss or tissue damage if left on for extended periods.

In medical scenarios, establishing the urgency of care is essential, and the tourniquet serves as a definitive solution when all other options have been exhausted. This placement allows for time-sensitive transport of the patient to a medical facility while effectively managing severe bleeding.
