What’s a spirometry lung function test?

ANSWER

Spirometry is the most common lung function test used for asthma. It's a simple, quick, and painless way to check your lungs and airways. You just take a deep breath and exhale into a hose attached to a device called a spirometer. It records how much air you blow out (FVC, or forced vital capacity) and how quickly you do it (FEV, or forced expiratory volume). Your doctor may also want readings taken during exercise to see how your airways react to exercise.
