How to Apply a Pressure Bandage Roller bandages can be used to maintain continuous pressure on a wound and control bleeding. A bandage applied snugly to the injured area will hold the dressing in place and facilitate blood clot- ting. To use a roller bandage: Place a dressing over the wound. Secure the roller bandage over the dressing. Using overlapping turns, cover the dressing completely, as shown in the diagram at the left. Secure the roller bandage in place by splitting its end into two strips. Tie the split bandage ends tightly over the wound. Make sure that the bandage is not so tight that it cuts off circulation. It should be just tight enough to maintain pressure on the wound. Pressure Point Bleeding Control If elevating the wound and applying a pressure bandage do not stop the bleeding, pressure point bleeding control must be used. This procedure involves pressing the main artery against a bone to stop blood supply to the injured area. Because this technique stops normal blood circulation, it should be used only when absolutely necessary. The diagram at the left shows the location of the points at which pressure should be applied when using this technique. A person who requires pressure point bleeding control is seriously injured and possibly in shock. Professional medical assistance is necessary and should be consulted before this procedure is applied. Burns eat, radiation from the sun, certain chemicals, H and electricity can all burn the skin and soft tissues of the body. Burns caused by heat are the most common. Those caused by chemicals or electricity require special first-aid procedures—for information on treating these types of burns, contact the American Red Cross. Burns are classified according to depth: first-degree burns are superficial, and second- and third-degree burns are deep. Minor burns can be treated at home. Severe burns, however, require professional medical care. Figure 28.2 shows the three classifications of burns and the treatment for each. For severe bleeding, applying pressure at a pressure point will reduce or stop blood flow. For what type of injury would pressure point bleeding control be necessary? A pressure bandage may be used to maintain con- tinuous pressure on a wound. Identify a situation that would require the use of a pressure bandage. 740 Chapter 28 First Aid and Emergencies HS_HEALTH_U09_C28_L1 12/8/03 6:02 PM Page 740

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
