Show Answers:

  1. arterial bleeding
    bleeding from an artery, which is characterized by bring red blood taht is rapid, profuse, and difficult to control
  2. capillary bleeding
    • bleeding from capillaries, which is characterized by a slow, oozing flow of blood
  3. cardiogenic shock
    shock, or lack of perfusion, brought on not by blood loss, but by the heart's inadequate pumping action. it is often the result of a heart attack or congestive heart failure
  4. compensated shock
    when the patient is developing shock but the body is still able to maintain perfusion. see shock
  5. decompensated shock
    when the body can no longer compensated for low blood volume or lack of perfusion. late signs such as decreasing blood pressure become evident. see shock
  6. hemorrhage
    bleeding, especially severe bleeding.
  7. hemorrhagic shock
     shock resulting from blood loss
  8. hemostatic agents
    • substances applied as powders, dressings, gauze, or bandages to open wounds to stop bleeding
  9. hypoperfusion
    the body's inability to adequately circulate blood to the body's cells to supply them with oxygen and nutrients. see also shock
  10. hypovolemic shock
    shock resulting from blood or fluid loss
  11. irreversible shock
    when the body has lost the battle to maintain perfusion to vital organs. even if adequate vital signs return, the patient may die days later due to organ failure
  12. neurogenic shock
    hypoperfusion due to nerve paralysis (some-times caused by spinal cord injuries) resulting in the dilation of blood vessels that increases the volume of the circulatory system beyound the point where it can be filled
  13. perfusion
    the supply of oxygen to, and removal of wastes from, the body's cells and tissues as a result of the flow of blood through the capillaries
  14. perssure dressing
    a bulky dressing held in position with a tightly wrapped bandage, which applies pressure to help control bleeding
  15. shock
    the body's inability to adequately circulate blood to the body's cells to supply them with oxygen and nutrietns, which is a life-threatening condition. Also known as hypoperfusion
  16. tourniquet
    a device used for bleeding control that constricts all blood flow to and from an extremity
  17. venous bleeding
    bleeding from a vein, which is characterized by dark red or maroon blood and a steady, easy to control flow
