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. Note: the information below is a general guide only.
Spirometry (measuring the lung capacity) is the most important test to diagnose and monitor COPD. COPD causes narrowing of the bronchial tubes (or airways), resulting in shortness of breath. The greater the narrowing, the more difficult breathing becomes. Spirometry is a test which measures exactly how much the bronchial tubes have narrowed. The spirometer measures the speed your lungs can be filled and emptied of air, giving an indication of how well your lungs are performing.
