In this respiratory physiology lecture, Professor Zach Murphy breaks down the concept of Airway Resistance, focusing on the factors that influence airflow through the respiratory tract and how changes in resistance affect breathing mechanics. We define by defining airway resistance as the opposition to airflow within the respiratory passages and explore its relationship to pressure gradients and flow rate, using Ohm’s Law (R = ΔP / Flow) as the foundation. The lecture highlights how resistance varies between the upper airways, trachea, bronchi, and bronchioles, and why the medium-sized bronchi are the primary site of resistance under normal conditions. You’ll learn how airway radius, lung volume, air viscosity, and turbulent vs laminar flow impact resistance, and how diseases like asthma, COPD, and bronchitis increase resistance by narrowing the airway lumen or increasing mucus production. We also cover the clinical relevance of dynamic airway compression, the importance of transpulmonary pressure, and how concepts like forced expiratory flow rates (e.g., FEV1) reflect changes in airway resistance.
