What is Spirometry?
Spirometry is a pulmonary function test measuring lung function, specifically the measurement of the amount (volume) and/or speed (flow) of air that can be inhaled and exhaled.
A special spirometer device is used. The patient places his or her lips around the blue mouthpiece found on the device and is asked to inhale and exhale according to the doctor's instructions. The results are then compared with values of patients of similar characteristics (sex, age, weight and height) and displayed on a computer screen.
