(1) The tourniquet should be placed accurately, and should be tied at the proximal end of the wound, and should be as close as possible to the wound. Forearms and calves are not suitable for tourniquets, because their arteries run between the two bones, so the hemostasis effect is poor, but not absolute. When the tourniquet is tied on the arm, it should not be tied at the lower 1/3 to avoid damaging the radial nerve.

(2) The pressure of tourniquet should be appropriate, and the degree is just that the distal arterial pulsation disappears and the bleeding can be stopped.

(3) Under the tourniquet, pad should be added, and direct pressure should not be applied with rope or iron wire.

(4) The wounded with tourniquet should be clearly marked, and the time of using tourniquet should be recorded and quickly transferred.

(5) The tourniquet should not be put on for more than 3 hours, and the tourniquet should be loosened 1 hour every 30 minutes.

(6) Before loosening the tourniquet, the blood volume should be supplemented first, and the equipment for correcting shock and stopping bleeding should be prepared.
