Tourniquets
If there is a detectable pulse, severe bleeding must be controlled, but tourniquets are dangerous
and should be used only as a last resort
. Don't use one unless you are willing to write off the
limb to save the victim. The only acceptable positions for tourniquets are around the upper arm,
just below the armpit, and around the upper thigh. Tourniquets should be made from material
that is at least 2 inches wide. If string or wire is used, the tourniquet must be padded with a
strip of heavy material. If a tourniquet has been applied, loosen the tourniquet every 20 minutes
to allow some circulation to the limb (only if this won't cause too much blood loss). Tourni-
quets should always remain visible, never covered by dressings, blankets, and so on. If a tour-
niquet is applied, the fingers or toes on the appropriate limb should remain uncovered to allow
for visual inspection for discoloration and swelling.
