Title: Lesson 4-1 Pathophysiology of Respiration and Perfusion
Course: EMS 1119 Emergency Medical Technician > Section: Module IV Pathophysiology

Apply a fundamental knowledge of the causes, pathophysiology and management of shock and the components of resuscitation

At the end of this lesson and the associated lab activities students will be able to:

Cognitive Learning Objectives

- 4-4.1 Discuss withholding resuscitation if irreversible death is obvious or if a “Do Not Resuscitate” (DNR) is present
- 4-4.2 Review the anatomy & physiology of the respiratory & cardiovascular systems
- 4-4.3 Discuss, identify pathophysiologies & medical care for respiratory failure as well as respiratory and cardiac arrest
- 4-4.4 Explain the system components of CPR, the four links in the AHA chain of survival & how each one relates to maximizing the survival of the patient
- 4-4.5 Show Provider (AHA guidelines) certification required prior to EMT program competition as per FS 401.27
- 4-4.6 Understand shock, including the pathophysiology, causes, and its signs and symptoms associated with the various types of shock
- 4-4.7 Discuss patient assessment and steps to the emergency care of the patient with signs & symptoms of shock
- 4-4.8 Discuss and distinguish the variations & causes between the emergency medical care of the infant, child, adult and geriatric patient experiencing shock
