In this respiratory physiology lecture, Professor Zach Murphy provides a clear and high-yield overview of Spirometry, focusing on measuring and interpreting lung volumes and capacities—a cornerstone of pulmonary function testing.

We begin by defining the core lung volumes, including tidal volume (TV), inspiratory reserve volume (IRV), expiratory reserve volume (ERV), and residual volume (RV). You’ll learn how these individual volumes combine to form lung capacities, such as vital capacity (VC), total lung capacity (TLC), functional residual capacity (FRC), and inspiratory capacity (IC).

The lecture explains which parameters are directly measured through spirometry and which must be calculated or inferred, and emphasizes the physiological significance of each measurement during normal breathing and forced maneuvers.

We also introduce how spirometry is used clinically to assess lung function in conditions like obstructive (e.g., asthma, COPD) and restrictive (e.g., pulmonary fibrosis, scoliosis) lung diseases.
