This video is the second in a series on pulmonary function tests, focusing on spirometry. It covers the objectives of understanding key spirometry measurements like FEV1, FVC, and the flow volume loop, and how these are used in diagnostic evaluations. The video explains the procedure of spirometry, how to interpret results, and the significance of different flow volume loop patterns. It also discusses the use of spirometry in diagnosing and staging COPD, including the response to bronchodilators.
