To take a spirometry test, you sit and breathe into a small machine called a spirometer. This medical device records the amount of air you breathe in and out and the speed of your breath. Spirometry tests are used to diagnose these conditions: COPD asthma restrictive lung disease (such as interstitial pulmonary fibrosis) other disorders affecting lung function They also allow your doctor to monitor chronic lung conditions to check that your current treatment is improving your breathing.
