What does a pulmonary function lab do?

A pulmonary function lab conducts tests to assess lung function, including measuring airflow, lung volume, and gas exchange. Pulmonary technicians or specialists operate specialized equipment to diagnose respiratory conditions such as asthma, COPD, and other lung diseases, often requiring knowledge of respiratory physiology and certification in pulmonary testing. These labs are typically located in hospitals or clinics and follow standardized testing protocols.
