How Healthy Are Your Lungs?
Spirometry is a test that can help diagnose various lung conditions, most commonly chronic obstructive pulmonary disease (COPD). Spirometry is also used to monitor the severity of some other lung conditions, and their response to treatment.
According the American Thoracic Society, spirometry is invaluable as a screening test of general respiratory health in the same way that blood pressure provides important information about general cardiovascular health.
The GOLD international COPD guidelines, as well as national guidelines, advise spirometry as the gold standard for accurate and repeatable measurement of lung function. Spirometry is also helpful in making a diagnosis in patients with breathlessness and other respiratory symptoms and for screening in occupational environments.
