|
arterial bleeding
|
bleeding from an artery, which is characterized by bright red blood that is rapid, profuse, and difficult to control.
|
|
|
capillary bleeding
|
bleeding from 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. See also shock.
|
|
|
decompensated 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. See also shock.
|
|
|
hemorrhage
|
(HEM-o-rej) bleeding, especially severe bleeding.
|
|
|
hemorrhagic shock
|
(HEM-or-AJ-ik) shock resulting from blood loss.
|
|
|
hemostatic agents
|
(HEM-o-STAT-IK) substances applied as powders, dressings, gauze, or bandages to open wounds to stop bleeding.
|
|
|
hypoperfusion
|
(HI-po-per-FEW-zhun) inability of the body to adequately circulate blood to the body's cells to supply them with oxygen and nutrients. Also called shock. See also perfusion, shock.
|
|
|
hypovolemic shock
|
(HI-po-vo-LE-mik) shock resulting from blood or fluid loss.
|
|
|
neurogenic shock
|
hypoperfusion due to nerve paralysis (sometimes caused by spinal cord injuries) resulting in the dilation of blood vessels that increases the volume of the circulatory system beyond the point where it can be filled.
|
|
|
perfusion
|
(pur-FEW-zhun) 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.
|
|
|
pressure dressing
|
a bulky dressing held in position with a tightly wrapped bandage, which applies pressure to help control bleeding.
|
|
|
shock
|
the body's inability 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.
|
|
|
tourniquet
|
(TURN-i-ket) 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 a steady, easy-to-control flow.
