A Spirometry is a medical test that measures how well the lungs exhale. The information gathered during this test is useful in diagnosing certain types of lung disorders, but it is most useful when assessing for obstructive lung diseases (especially asthma and chronic obstructive pulmonary disease (COPD)).
In a spirometry test, a person breathes into a mouthpiece that is connected to an instrument called a spirometer. The spirometer records the amount and the rate of air that is breathed in and out over a specified time. Some of the test measurements are obtained by normal, quiet breathing, and other tests require forced inhalation or exhalation after a deep breath.
