What is a spirometry test?

Spirometry is a simple test used to help diagnose and monitor certain lung conditions by measuring how much air you can breathe out in one forced breath. It's carried out using a device called a spirometer, which is a small machine attached by a cable to a mouthpiece.

What is spirometry used for?

Spirometry is used to diagnose asthma, chronic obstructive pulmonary disease (COPD) and other conditions that affect breathing. Spirometry may also be used periodically to monitor your lung condition and check whether a treatment for a chronic lung condition is helping you breathe better.

Can spirometry be used to monitor a lung condition?

If you have an ongoing lung condition regular spirometry may be used to monitor it. In addition, you may be asked to carry out some more tests if the doctor needs to investigate further. Spirometry can also be part of other lung function testing, like an exercise test or a bronchial challenge test.

What spirometry measurements are used?

The most common spirometry measurements used are: Forced expiratory volume in one second (FEV1). This is the amount of air you can blow out within one second. With normal lungs and airways you can normally blow out most of the air from your lungs within one second.
