Pulmonary Function Assessment

Mayra Colón, explains what pulmonary function tests (PFTs) are and why they are essential for diagnosing and monitoring interstitial lung disease, including pulmonary fibrosis. She details spirometry, lung volumes (plethysmography), and diffusion capacity (DLCO), as well as the 6-minute walk test to evaluate oxygenation and exercise tolerance. She clarifies the difference between obstructive and restrictive patterns, the impact of age, and how to interpret basic charts. She concludes by emphasizing the importance of periodic monitoring and active communication with the medical team.
