    Capillary bleeding.
  25. Severity of the bleeding dependent on?
    Relation of blood lost in relation to the physical size of the patient, and dependent on the patient's condition.

    Adult
    Child
    Infant
    • 1 liter-Adult
    • 500 cc- Child
    • 150 cc- Infant.
  27. If the patient even begin to exhibit signs and symptoms of shock, then what?
    Bleeding is considered serious.
  28. What is the body's natural response to bleeding?
    Constriction of the injured blood vessel and clotting.
  29. What are the general signs of shock?
    Altered mental status, pale cool clammy skin, nausea and vomiting, and vital sign changes are signs of?
  30. What are the vital sign changes in shock?
    These are S&S of what?

    • PULSE UP, WEAK AND THREADY
    • RESP UP SHALLOW AND LABORED
    • BP LAST TO CHANGE
    • NARROWING OF PULSE PRESSURE MAY ALSO OCCUR. (SYSTOLIC DIASTOLIC GET CLOSER)
  31. What happens to pulse in shock?
    Pulse goes up, gets weak and thready.
  32. What happens to respirations in shock?
    Increase and becomes more shallow and labored.
  33. What happens to BP with shock?

  35. What are major methods of controlling external bleeding?
    Other methods?
    • Direct pressure, Elevation, Pressure points.
    • Splinting, cold application, pasg. Tourniquit last resort.
  36. Blood loss decreases what?
    Perfusion.
  37. What is the most common and effective way to control external bleeding?
    By applying direct pressure to the wound.
  38. How do you apply direct pressure?
    • 1.) Apply pressure until controlled.
    • 2.) Hold pressure firmly until bleeding controlled.
    • 3.) Once controlled bandage dressing firmly in place to form pressure dressing.
    • 4.)Never remove dressing once it has been placed on wound.
  39. What is a pressure dressing?
    bulky dressing held in position with a tightly wrapped bandage to apply pressure to help control bleeding.

    This is known as what?
  40. What is process of controlling bleeding?
    • 1.)Apply direct pressure
    • 2.) Elevate above level of the heart
    • 3.) if wound continues to bleed, apply additional dressing over the first one.
    • 4.) Bandage dressing in place.
    • 5.) if wound continues to bleed, apply pressure to pressure point.
  41. After applying a bandage what do you do?
    Check for distal pulses
  42. When should elevation not be done?
    When musculoskeletal injuries, impaled obects, or spine injury.
  43. How high should elevation be done?
    Above the level of the heart.
  44. What is a pressure point?
    Where large artery lies close to the surface of the body and directly over a bone.
  45. When should pressure point method of controlling bleeding be used?
    After direct pressure and elevation have failed.
  46. Bleeding associated with _________ may be controlled by proper splinting of the injury.
    Bleeding associated with musculoskeletal injury may be controlled by _______.
  47. Air splints are most effective for what types of bleeding?
    Venous and capillary
  48. How does the cold application work?
    It minimizes swelling and reduced the bleeding by constricting the blood vessels. Will also reduce pain at the injury site.
