Once an improvised tourniquet is tightened, what must be done next?

When an improvised tourniquet is tightened, the next important step is to secure the windlass. This action is crucial because it maintains the pressure applied by the tourniquet on the affected limb, effectively controlling the bleeding. The windlass is typically a rod or stick that, when turned, increases the tension of the tourniquet. By securing it, you ensure that it stays in place and continues to occlude blood flow until further medical assistance can take over.

Maintaining pressure is critical in life-threatening situations where there is severe bleeding. Untightening or removing a tourniquet, as would happen if checking for a pulse or for comfort, could cause a rapid return of blood flow, leading to a potentially fatal situation if the wound is not adequately controlled. Although notifying medical personnel is important, it is not an immediate next step after applying the tourniquet. The immediate focus must be on stabilizing the situation, which includes securing the tourniquet.
