Flashcards in Ch 10: Shock Deck (12):
A series of body responses to compensate for inadequate blood flow to the vital organs.
Types of Shock
Life threatening allergic reaction to a substance
Failure of the heart to effectively pump blood to all parts of the body
Sever lack of blood and fluid in the body
Failure of the nervous system to control size of blood vessels, causing them to dilate.
Factors such as emotional stress cause blood to pool in the body in areas away from the brain because of vessels dilating.
Failure of the lungs to transfer sufficient oxygen into the bloodstream
Poisons caused by severe infection that cause blood vessels to dilate
How Shock Develops
The heart adjusts its speed and force of its contractions to meet the body's changing demands for oxygen
Because the heart is beating faster, breathing must also speed up
The body is unable to adjust properly due to illness or injury and shock occurs
The body ensures adequate blood flow to the vital organs by shunting blood from the extremities, causing changes to the patients vitals
Signs and Symptoms of Shock

-Listlessness / Confusion
-Slow, shallow irregular breathing
