Terms | Definitions |
|---|---|
 Arterial Bleeding | Bleeding from an artery, which is characterized by bright red blood and as rapid, profuse, and difficult to control. |
| Brachial Artery | The major artery of the upper arm. |
| Capillary Bleeding | Bleeding from the capillaries, which is characterized by a slow oozing flow of blood. |
| Cardiogenic 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. |
| Compensated Shock | When the patient is developing shock but the body is still able to maintain perfusion. |
| Decompensated Shock | Occurs when the body can no longer compensate for low blood volume or lack of perfusion. Late signs such as decreasing blood pressure become evident. |
| Femoral Artery | The major artery supplying the thigh. |
| Golden Hour | Refers to the optimum limit of one hour between time of injury and surgery at the hospital. |
| Hemorrhage | Bleeding, especially severe bleeding. |
| Hemorrahagic Shock | Shock resulting from blood loss. |
| Hypoperfusion | Inability of the body to adequately circulate blood to the body's cells to supply them with oxygen and nutrients. |
| Hypovolemic Shock | Shock resulting from blood or fluid loss. |
| 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. |
| Neurogenic Shock | Hypoperfusion due to nerve paralysis (sometimes caused by spinal cord injuries) resulting in the dialation of blood vessels that increses the volume of the circulatory system beyond the point where it can be filled. |
| Pefusion | The supply of oxygen to and removal of wastes from the cells and tissues of the body as a result of the flow of blood through the capillaries. |
| Platinum Ten Minutes | Refers to an optimum limit of ten minutes at the scene with a serious trauma patient. |
| Pressure Dressing | A bulky dressing held in position with a tightly wrapped bandage to apply pressure to help control bleeding. |
| Pressure Point | A site where a main artery lies near the surface of the body and directly over a bone. Pressure on such a point can stop distal bleeding. |
| Shock | The inability of the body to adequately circualte blood to the body's cells to supply them with oxygen and nutrients. A life-threatenting condition. |
| Tourniquet | A device used for bleeding control that constricts all blood flow to and from an extremity. |
| Venous Bleeding | Bleeding from a vein, which is characterized by dark red or maroon blood and as a steady flow, easy to control. |
