1

Shock

A series of body responses to compensate for inadequate blood flow to the vital organs.

2

Types of Shock

Anaphylactic
Cardiogenic
Hypovolemic
Neurogenic
Psychogenic
Respiratory
Septic

3

Anaphylactic Shock

Life threatening allergic reaction to a substance

4

Cardiogenic Shock

Failure of the heart to effectively pump blood to all parts of the body

5

Hypovolemic Shock

Sever lack of blood and fluid in the body

6

Neurogenic Shock

Failure of the nervous system to control size of blood vessels, causing them to dilate.

7

Psychogenic Shock

Factors such as emotional stress cause blood to pool in the body in areas away from the brain because of vessels dilating.

8

Respiratory Shock

Failure of the lungs to transfer sufficient oxygen into the bloodstream

9

Septic Shock

Poisons caused by severe infection that cause blood vessels to dilate

10

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
