📖About Pulmonary Function Test
A pulmonary function test (PFT) is a comprehensive set of breathing tests that measure lung volume, airflow rates and gas exchange efficiency to evaluate overall lung function. It goes beyond basic spirometry to include measurements such as total lung capacity and diffusion capacity, providing a fuller picture of both obstructive and restrictive lung diseases. PFTs are used to diagnose conditions, assess disease severity, monitor progression over time, and evaluate fitness for surgery or high-risk occupations. The detailed data helps physicians distinguish between different types of lung disease that may present with similar symptoms.
