Lung function basics

The process of measuring lung function capacity — or the ability to inhale or exhale — is known as pulmonary function testing (PFT) or spirometry. These tests serve to help determine overall lung function, which can help diagnose chronic lung diseases, including asthma and Chronic Obstructive Pulmonary Disease (COPD).

Below, we've compiled this easy to follow and understand series of frequently asked questions (FAQs) about lung function basics.
