Understanding Shock: Types and Characteristics

Introduction

• Presenter: Evan, the paramedic coach
• Topic: In-depth breakdown of different types of shock
• Objective: To thoroughly understand each type of shock

Types of Shock

1. Cardiogenic Shock

• Definition: Shock resulting from the heart's inability to function properly
• Causes:
  • Heart Failure (CHF): Heart is too weak, fails as a pump
  • Myocardial Infarction (MI): Heart muscle damage due to blocked coronary artery
• Key Point: The heart itself is the primary problem

2. Obstructive Shock

• Definition: Shock caused by an obstruction preventing blood flow
• Causes:
  • Pulmonary Embolism: Blockage in pulmonary artery
  • Tension Pneumothorax: Pressure buildup obstructing heart function
  • Cardiac Tamponade: Pressure around the heart squeezing it
• Key Point: An external obstruction is the cause, not the heart itself

3. Distributive Shock

• Definition: Shock due to abnormal vasodilation causing improper blood distribution
• Subtypes:
  • Sepsis: Bacterial infection in the blood, commonly from lungs (pneumonia) or urinary tract infections
  • Anaphylaxis: Severe allergic reaction affecting multiple body systems
  • Neurogenic: Related to brain and spinal cord issues
• Key Point: No natural epinephrine/norepinephrine compensation, leading to severe vasodilation

4. Hypovolemic Shock

• Definition: Shock due to decreased blood volume
• Causes:
  • Trauma: Major bleeding events such as shootings, stabbings
  • Severe Dehydration: Loss of body fluids, significant in pediatrics
• Key Point: Can result from both traumatic and non-traumatic loss of fluids
