Lesson 7: Shock
Lesson Objectives
After completing this lesson, participants should be able to:
Recognize the signs and symptoms of shock.
Describe and demonstrate how to care for shock.
Identify signs of anaphylactic shock.
Describe and demonstrate how to use an epinephrine auto-injector.
Points
Shock
Perfusion is when adequate blood and oxygen are provided to all cells in different
tissues and organs in the body.
Shock describes a state of collapse or circulatory system failure, which results
when insufficient amounts of oxygenated blood are provided for every body part.
The circulatory system has three components:
o A working pump (the heart)
o A network of pipes (the blood vessels)
o An adequate amount of fluid (the blood)
Circulatory system failure
o Pump (heart) failure
o Fluid loss
o Pipe failure (blood vessels)
Perfusion Triangle
These three components are known as the perfusion triangle.
Types of Shock
Cardiogenic
Hypovolemic
Neurogenic
Septic
Anaphylactic
Psychogenic
Recognizing Shock
Altered mental status
Pale, cold, and clammy skin
Nausea and vomiting
Rapid breathing and pulse

Recognizing Anaphylaxis
Skin

o Hives
o Swelling, especially of the face, tongue, and lips
o Bluish lips (cyanosis)
Circulatory System
o Weak pulse
o Dizziness
o Fainting and unresponsiveness
Respiratory System
o Sneezing or itching in the nostrils
o Tightness in the chest
o Breathing difficulty
o Secretions of fluid and mucus
o Wheezing
o Breathing stops
Care for Anaphylaxis
Monitor breathing and administer CPR, if necessary.
Call 9-1-1 immediately.
Help victim use prescribed epinephrine auto-injector if he or she has one.
