Bleeding and Shock I
Terms and definitions- bleeding and shock
| Question | Answer |
|---|---|
| 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 |
