Chapter 29 Flashcards
Arterial bleeding:
Bleeding, from an artery, which is
characterized by brigh
red blood and 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 the heart’s inadequate pumping action. It is often the result of heart attack or heart failure.
Compensated shook:
When the patient is developing shock but the body
still able to maintain perfusion.
Decompensated
shock:
When the body can no longer
compensate a shock state which results in hypotension and death.
Hemorrhage:
Bldeding, especially severe bleeding.
Hemorrhagic shock:
Shock resulting from blood loss.
Hemostatic agenis:
Substances applied as powders, dressings, gauze, or bandages to open wounds to stop bleeding.
Hypoperfusion:
The body’s inability to adequately
circulate blood to the lody’s cells to supply them with
Hypovolemic shock:
Shock resulting from blood or fluid loss.
Neurogenic shock;
Hypoperfusion caused by a spinal cord injury that results in systemic vasodilatation.
Perfusion:
The supply of oxygen to, and removal of wastes from, the cells and tissues of the body as a result of blood flow through the capillaries.
Pressure dressing:
A bulky dressing held in position with a tightly wrapped bandage, which applies pressure to help control bleeding.
Shock:
A general or lay term used to describe the inability to adequately circulate blood to the body’s cells in order to supply them with oxygen and nutrients; a life-threatening condition.
Tourniquet:
A device used for bleeding control that constricts all blood flow to and from an extremity.
