What happens during a pulmonary function test?

Breathing test: The pulmonary function test measures how well air moves in and out of the lungs and what you lung capacity is. Basically you blow into a machine. You may be asked to use an inhaler and the test may be repeated to see if there is any change in the measurements. The pulmonary function test is an important part of an asthma or COPD evaluation and is used to follow your progress to treatment.
