Lesson Title: Anatomy of the Respiratory System Duration: 15 min Course Goal: To prepare Firefighters to respond to medical emergencies within the tiered response system. Learning Objective: Given a diagram, the Firefighter will identify the parts of the Respiratory System. Reference: IFSTA Fire Service Emergency Care Prepared by: John Wilmot Date Prepared: 01 05 15 Updated: Review: When we learned how to perform a primary survey we learned that for a patient to survive we must ensure that the patient's ABCs are present. Who remembers what the ABCs stand for? Introduction: The Airway and Breathing portion of the primary survey deal directly with the Respiratory System. Breathing is the process of absorbing the oxygen we need out of the air and expelling the carbon dioxide that our body produces. The Respiratory System is what makes that process happen. What: Why: In this lesson you will learn the parts of the respiratory system. It is important to know what the parts are so that you can understand what is happening inside a person who is in respiratory distress. This knowledge is used at all medical calls when you assess the airway and breathing of your patient. There will be a short written test at the end of the lesson where you will have to label a diagram of the respiratory system. Methodology Practical Exercise Where: Test: Contents Let's start by everyone taking a few deep breaths. Can you feel the air moving inside of your body? All of the areas that the air is passing through are part of your respiratory system. The parts are: PowerPoint Display Pharynx - including the nasopharynx and the oropharynx, Epiglottis, Larynx - including the thyroid cartilage and the cricoid cartilage, Bronchus, Bronchioles, Alveolar Sacs, Alveolus, Lungs and Diaphragm Test: Distribute diagrams of the Respiratory System. Label the parts of the respiratory system on this diagram. Review the answers with the class. We have learned the parts of the respiratory system. This will help us to understand what is happening inside a patient in respiratory distress. You should keep this information in mind whenever you assess a patient's airway and breathing. Conclusion: Our next lesson will be on the different kinds of respiratory emergencies and how to deal with them.
