Bleeding & Shock
Brady EMT Basic - chapter 27- Bleeding and Shock
| Question | Answer |
|---|---|
| the supply of oxygen to and removal of wastes from the body's cells and tissue as a result of the flow of blood through the capillaries | Perfusion |
| the body's inability to adequately circulate blood to the body's cells to supply them with oxygen and nutrients | Hypoperfusion |
| The body's ability to adequately circulate blood to the body's cells to supply them with oxygen and nutrients, which is a life threatening condition. also known as hypoperfusion | Shock |
| bleeding, especially severe bleeding | Hemorrahage |
| bleeding from an artery, which is characterized by bright red blood that is rapid, profuse, and difficult to control | Artierial Bleeding |
| bleeding from the vein, which is characterized by dark red or maroon blood and a steady easy to control flow | Venous Bleeding |
| bleeding from the capillaries, which is characterized by a slow, oozing flow of blood | Capillary Bleeding |
| a bulky dressing held in position with a tightly wrapped bandage, which applies pressure to help control bleeding | Presure Dressing |
| substances applied as powders, dressings, gauzes, or bandages to open wounds to stop bleeding | Hemostatic Agents |
| a device used for bleeding control that constricts all blood flow to and from an extremity | Tourniquet |
| when the patient is developing shock but the body is still able to maintain perfusion | Compensated Shock |
| when the body can no longer compensate for low blood volume or lack of perfusion. Late signs such as decreasing blood pressure become evident | Decompensated 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 | Irreversible Shock |
| shock resulting from blood or fluid loss | Hypovelemic |
| shock resulting from blood loss | Hemorhagic Shock |
| shock, or lack of perfusion, brought on not by blood loss, but by inadequate pumping action of the heart. It is often the result of a heart attack or congestive heart failure | Cardiogeneic Shock |
| hypoperfusion due to nerve paralysis (sometimes caused by spinal cord injuries) resulting in the dilation of blood vessels that increase the volume of the circulatory system beyond the point where it can be filled. | Neurogenic Shock |
| The Major Artery in the upper Arm | Brachial Artery |
| The Upper Artery supplyling the Thigh | Femoral Artery |
| A Site where a main Artery lies near the surface of body and directly over the bone; pressure on such a point can stop distal bleeding | Pressure Point |
