Tourniquet

Definition: A tight band placed around an arm or leg to stop severe bleeding when direct pressure is not enough. Tourniquets save lives in major bleeding emergencies and are now part of the Stop the Bleed program taught to bystanders, schools, and first responders.

Parent Tip: A tourniquet is for life threatening bleeding that cannot be controlled by direct pressure, like a deep cut to an arm or leg that is spurting or pooling blood. Place the tourniquet 2 to 3 inches above the wound, between the wound and the heart, but not directly on a joint. If you only have 1 tourniquet or you are using an improvised tourniquet, make sure you go high and tight (above the elbow or knee). Tighten it until the bleeding stops or you can no longer turn it. Note the time you applied it, write it on the tourniquet and do not remove it. Once a tourniquet is on, only a hospital should take it off.

For Children

• Tourniquets can be used on children over the age of 2 with the same technique as adults
• For children under 2, direct pressure and pressure dressings should be the first response, since tourniquets sized for children that small are not standardized
• If a child under 2 has uncontrolled major bleeding, apply firm direct pressure with whatever clean material you have and call 911 immediately
• Always call 911 anytime a tourniquet is applied

Why It Matters: Severe bleeding can become fatal in just a few minutes. A properly applied tourniquet stops the bleeding and buys time until paramedics arrive. The Stop the Bleed program was created because research showed that bystanders willing to act in the first few minutes save more lives than any equipment paramedics carry. Knowing how to use a tourniquet is one of the most valuable safety skills a parent can learn.
