Quick Answer
To secure a tourniquet effectively, it should be positioned on the affected limb between the wound site and the heart, and tightened with a windlass or strap until bleeding slows or stops. The tourniquet should be applied quickly and with confidence. A properly secured tourniquet can help control severe bleeding.
Applying the Tourniquet
When applying a tourniquet, start by positioning it on the affected limb, between the wound site and the heart. This is typically above the elbow or knee. The tourniquet should be snug, but not too tight, to prevent further injury. The windlass or strap should be turned in a clockwise direction to tighten the tourniquet. For a CAT tourniquet, this is typically 2-3 windlass turns. Be cautious not to over-tighten, as this can cause nerve damage or other complications.
Securing the Tourniquet
Once the tourniquet is tightened, it should be secured with a windlass pin or strap to prevent it from loosening. The windlass should be locked in place to prevent further adjustments. The tourniquet should be left in place until medical help arrives, unless the patient’s condition worsens or they show signs of tourniquet-related complications. In these cases, the tourniquet should be loosened and re-applied if necessary.
