  1. LESSON 8 CONTROLLING BLEEDING 8-1

  2. Bleeding • Many injuries cause external or internal bleeding • May be minor or life threatening • Most external bleeding is not severe and can be controlled

  3. Effects of Blood Loss • Body can compensate for small blood loss • Severe blood loss (> 30%) results in lack of oxygen and shock • In infants and children, severe bleeding becomes critical more quickly

  4. External Bleeding • Occurs when skin and other tissues damaged and blood escapes • Rate of bleeding depends on size and type of damaged vessels • Injury to major vessel close to skin surface as in the case of the scalp and face may cause heavy bleeding

  5. Types of External Bleeding

  6. Controlling External Bleeding • First aid needed immediately to stop bleeding • Apply direct pressure on wound covered with sterile dressing • Press directly with gloved hand or improvised barrier

  7. Pressure Bandages • Apply if neededover wound on extremity to maintain direct pressure • Use roller bandage to completely cover wound and maintain pressure • Make sure it doesn’t cut off circulation • Check victim’s fingers and toes for circulation

  8. Preventing Bloodborne Infection • Follow standard precautions • Use a barrier (e.g., gloves, plastic wrap, victim’s own hand) • Wash hands immediately before touching anything else • Dispose of soiled supplies appropriately • Disinfect all contaminated items

  9. Internal Bleeding • Any bleeding within body when blood does not escape • Can be life threatening • Consider the mechanism of injury

  10. Signals of Internal Bleeding • Signals include— • Soft tissues, such as those in the abdomen, that are tender, swollen or hard. • Anxiety or restlessness. • Rapid, weak pulse. • Rapid breathing, shortness of breath. • Skin that feels cool or moist and looks pale, ashen or bluish. • Bruising in the injured area. • Nausea and vomiting or coughing up blood. • Abdominal pain. • Excessive thirst. • A decreasing level of consciousness. • Severe headache.

  11. Care for Internal Bleeding • If there is minor internal bleeding, such as bruising, apply ice. • If you suspect internal bleeding, call 9-1-1 or the local emergency number immediately. • Follow these general care steps: • Do no further harm. • Monitor signs of life and consciousness. • Help the victim rest comfortably. • Keep the victim from getting chilled or overheated. • Reassure the victim. • Give any specific care needed.
