Instructions

• 1

  Put on latex gloves to minimize the risk of disease transmission.

• 2

  Determine if a tourniquet is necessary (see "How to Treat Severe Bleeding During First Aid").

• 3

  Gather the materials: a bandanna or cravat and a stick that won't break. If no sticks are available, use a trekking pole.

• 4

  Fold the bandanna in half, from corner to corner; if using a cravat, don't perform this step. (The point is to form a right triangle, which cravats naturally are, whereas bandannas are square.)

• 5

  Grab the corners that form the long side of the triangle and fold 3 to 4 inches toward the third corner.

• 6

  Fold again and again in this manner until you've reached the third corner. You should now have a bandage 3 to 4 inches wide and several layers thick.

• 7

  Tie the bandage with gauze around the appropriate limb between the wound and the heart, as close as possible to the wound but above the knee or elbow. Use an overhand knot (the same as the first stage in tying a shoe).

• 8

  Place the stick on top of the knot and tie a second overhand knot over the stick.

• 9

  Twist the stick until it pulls the bandage tight enough to stop the bleeding.

• 10

  Tie the ends of the bandage around the limb and secure the stick with gauze.

• 11

  Write "TK" on the injured person's forehead in pen, along with the time of application.

• 12

  Splint the wounded area to avoid movement, which could restart bleeding (see eHows on splinting).

• 13

  Get the injured person to a hospital as quickly as possible. If a hospital is more than an hour away, check the bleeding every 10 minutes by slowly loosening the tourniquet to see if clotting has stopped the bleeding. If so, clean and bandage the wound (see "How to Clean a Wound During First Aid" and "How to Bandage a Wound During First Aid"). If not, retighten the tourniquet and check again in 10 minutes.
