Pulmonary Function Testing
Pulmonary function testing is used to measure lung capacity. This test may be used to evaluate conditions such as asthma and chronic obstructive pulmonary disease. Pulmonary function testing is painless, and requires approximately 5 minutes to perform. Spirometry (meaning the measuring of breath) is the most common of the Pulmonary Function Tests (PFTs), measuring lung function, specifically the measurement of the amount and/or speed of air that can be inhaled and exhaled. Spirometry is an important tool used for generating pneumotachograph to assessing conditions such as asthma, pulmonary fibrosis, and COPD.
