How tight is too for a tourniquet?

A tourniquet should be tight enough to stop the bleeding, but not so tight that it cuts off the blood supply to the limb.

If a tourniquet is too tight, it can cause:

- Tissue damage

- Nerve damage

- Loss of limb

It is important to loosen the tourniquet every 15-20 minutes to allow blood to flow back into the limb. If the bleeding does not stop after 2-3 minutes, the tourniquet should be loosened and reapplied.
