Pulmonary Function Tests (PFTs) are a group of tests that measure how well your lungs work. These tests can evaluate how much air your lungs can hold, how quickly you can move air in and out of your lungs, and how well your lungs can exchange oxygen and carbon dioxide. PFTs are crucial for diagnosing and monitoring lung diseases such as asthma, chronic obstructive pulmonary disease (COPD), and pulmonary fibrosis.
