making a splint

Attend to any bleeding before you attempt to place the splint. You can stop the bleeding by putting pressure directly on the wound. Then, apply a bandage, a square of gauze, or a piece of cloth. Do not try to move the body part that needs to be splinted—you may accidentally cause more damage.
Place the splint so that it rests on the joint above the injury and the joint below it. For example, if you are splinting a forearm, place the rigid support item under the forearm. Then, tie or tape it to the arm just below the wrist and above the elbow.

Avoid placing ties directly over the injured area. You should fasten the splint tightly enough to hold the body part still, but not so tightly that the ties will cut off the person’s circulation.
Once the splint is applied, you should check the areas around it every few minutes for signs of decreased blood circulation. If the extremities begin to appear pale, swollen, or tinged with blue, loosen the ties that are holding the splint.

If the injured person complains that the splint is causing pain, try loosening the ties a little. Then, check that no ties were placed directly over an injury. If these measures do not help and the person is still feeling pain from the splint, you should remove it.
