Ch 29 Bleeding and Shock Flashcards
The supply of oxygen to, and removal of wastes from, the body’s cells and tissues 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
Another name for hypoperfusion
Shock
Shock resulting from blood or fluid loss
Hypovolemic shock
Shock resulting from blood loss, specifically
Hemorrhagic shock
Lack of perfusion brought on not by blood loss but by the heart’s inadequate pumping action; often the result of MI or CHF
Cardiogenic shock
Hypoperfusion due to a lack of blood vessel tone; blood vessel dilation leads to decreased pressure within the circulatory system
Distributive shock
Hypoperfusion caused by a spinal cord injury that results in systemic vasodilation
Neurogenic shock
A term commonly used to describe the different conditions that block the flow of blood and cause hypoperfusion
Obstructive shock
Period when the patient is developing shock but the body is still able to maintain perfusion
Compensated shock
Period 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
Bleeding, especially severe bleeding
Hemorrhage
Characterized by bright red blood that is often spurting, profuse, and difficult to control
Arterial bleeding
Characterized by dark red or maroon blood and a steady, easier-to-control flow
Venous bleeding
Characterized by a slow, oozing flow of blood
Capillary bleeding
