What is Spirometry?
Expert pulmonologists describe spirometry and how it is used to diagnose COPD. Spirometry is used to identify obstruction by measuring how much air you can breathe out, and how fast you blow air out. The experts explain forced expiratory volume (FEV-1)
and forced vital capacity (FVC) and how the values are compared and interpreted in order to diagnose COPD. Spirometry is also called a breathing test or a lung function test or a pulmonary function test.
