Bleeding and Shock I

Terms and definitions- bleeding and shock

Major artery of the upper arm brachial artery
When the patient is developing shock, but the body is still able to maintain perfusion. compensate shock
Bleeding that is characterized by a slow, oozing flow of blood. capillary bleeding
Shock resulting from blood loss. hemorrhagic shock
Condition that occurs when the body can no longer compensate for low blood volume or lack of perfusion; late signs such as falling blood pressure develop decompensated shock
Major artery supplying the thigh. femoral artery
Lack of perfusion brought on by inadequate pumping action of the heart. cardiogenic shock
Optimum time limit between time of injury and surgery at the hospital; survival rates are best during this time golden hour
Blood vessel with thick, muscular walls that carries blood away from the heart. artery
Device that closes off all blood flow to and from an artery. tourniquet
Blood vessel that has one way valves and carries blood back to the heart. Blood is depleted of oxygen and loaded with carbon dioxide. vein
Adequate circulation of blood throughout the body, filling the capillaries and supplying the cells and tissues with oxygen and nutrients. perfusion
Site where a large artery lies near the surface of the body and directly over a bone; pressure on such a location can control profuse bleeding in the extremeties. pressure point
When the body has lost the battle to maintain perfusion to the organ systems; cell damage occurs, especially to the liver and kidneys. irreversible shock
Another term for hypoperfusion. shock
Bulky dressing held in place with a tightly wrapped bandage, used to help control bleeding. pressure dressing
Shock resulting from uncontrolled bleeding or plasma loss. hypovolemic shock
Shock resulting from uncontrolled dilation of blood vessels due to nerve paralysis, sometimes caused by spinal cord injuries. neurogenic shock
Inadequate circulation of the blood in which the body's cells and organs do not receive adequate supplies of oxygen and dangerous waste products build up. hypoperfusion
These cells and tissues are the most sensitive to inadequate perfusion. brain, spinal cord, kidneys
Always use these precautions when bleeding is discovered or anticipated. BSI precautions
This type of bleeding is rapid and profuse. arterial bleeding
A steady flow of dark red or maroon blood is a result of this type of bleeding. venous bleeding
Oozing bleeding is usually a result of this type of bleeding. capillary bleeding
When a large bleeding vein in the neck sucks in debris or an air bubble, this can happen. heart stoppage
Sudden blood loss of ___ in an adult is considered serious. 1,000 cc
Sudden blood loss of ___ in a child is considered serious. 500 cc
Sudden blood loss of ___ in a one year old infant is considered serious. 150cc
The body naturally responds to bleeding by constricting the injured blood vessel and clotting.
The EMT-B's assessment of external bleeding includes: estimating the amount of blood lost to predict potential shock, triaging/prioritizing injured patients, identifying bleeding that must be treated.
These methods can be used to control external bleeding.(The best method is...) direct pressure, elevation, pressure points (direct pressure)
Supplemental oxygen is an important treatment because it improves oxygenation of tissues.
The initial dressing should not be removed from a bleeding wound because it is part of clot formation
