Spirometry (spy-ROM-uh-tree) is a common office test used to assess how well your lungs work by measuring how much air you inhale; how much you exhale and how quickly you exhale.
Spirometry is used to diagnose asthma, chronic obstructive pulmonary disease (COPD) and other conditions that affect breathing:
Conditions that can be picked up and monitored using spirometry include:
- asthma – a long-term condition in which the airways become periodically inflamed (swollen) and narrowed
- chronic obstructive pulmonary disease (COPD) – a group of lung conditions where the airways become narrowed
- cystic fibrosis – a genetic condition in which the lungs and digestive system become clogged with thick, sticky mucus
- pulmonary fibrosis – scarring of the lungs
