14-11 PROCEDURE STEPS Constricting band (Continued) A constricting band must always be applied above the wound; that is, toward the body, and it must be applied as close to the wound as practicable. The best object to be used for the pad is either a pad, compress, or similar pressure object. The pad goes under the band. Place it directly over the artery, or it will actually decrease the pressure on the artery and allow greater flow of blood. If a constricting band placed over a pressure object doesn’t stop the bleeding, the pressure object is probably in the wrong place. If that occurs, shift the object around until the constricting band, when tightened, controls the bleeding. If no suitable pressure object is available, use the constricting band without it. To apply an emergency constricting band (fig. 14-13) made from something like a neckerchief— 1. Wrap the material (which is a minimum of 2 inches wide) at least twice around the limb and tie an overhand knot. 2. Place a short stick on the overhand knot and tie a square knot over it. Then twist the stick rapidly to tighten the constricting band. The stick may be tied in place with another strip of material. To be effective, a constricting band must be tight enough to stop the blood flowing to the limb. If the pressure from the constricting band is less than the arterial pressure, arterial bleeding will continue. Also, insufficient constricting band pressure may actually increase the amount of bleeding from the veins. So be sure to draw the constricting band tight enough to stop the bleeding. However, don’t make it any tighter than necessary. After you have brought the bleeding under control with the constricting band, apply a sterile compress or dressing to the wound, and fasten it in position with a bandage. Some points to remember about using a constricting band are as follows: Don’t use a constricting band unless you can’t control the bleeding by any other means. Don’t use a constricting band for bleeding from the head, face, neck, or body. Use one only on the limbs. Always apply a constricting band above the wound and as close to the wound as possible. Be sure you draw the constricting band tight enough to stop the bleeding, but don’t make it any tighter than necessary. Don’t loosen a constricting band after it has been applied. Don’t cover a constricting band with a dressing. If it’s necessary to cover the injured person in some way, make sure all other people concerned with the case know about the constricting band. Using a crayon, skin pencil, or blood, make a large T on the victim’s forehead or on a medical tag attached to the wrist, and note the time the constricting band was applied.
