Spirometry is the most common of the lung function tests. These tests look at how well your lungs work. Spirometry shows how well you breathe in and out. Breathing in and out can be affected by lung diseases such as chronic obstructive pulmonary disease (COPD), asthma, pulmonary fibrosis and cystic fibrosis.
The doctor can also take a picture of your lungs using a chest x-ray or CAT scan to look for abnormalities in the structure of the lungs, such as an infection like pneumonia. However, these two tests can still miss important problems. For this reason, a breathing test, called spirometry, is often done to further evaluate the health of the lungs. Spirometry can tell you how much air is going into the lungs and how rapidly air is inhaled and exhaled in the lungs (airflow).
