Spirometry is a breathing test to find out how well your lungs are working.
It is tested using a device called a spirometer.
It is a simple test that is not painful and takes 15 to 30 minutes.
It measures lung function, specifically the amount and/or speed of air that can be inhaled and exhaled.
Spirometry is helpful in assessing breathing patterns that identify conditions such as asthma, pulmonary fibrosis, cystic fibrosis, and COPD.
