Lung Function Testing
Lung function testing (spirometry) can evaluate a broad range of lung diseases by measuring how much air you exhale and how quickly. The test involves placing a mouthpiece connected to the spirometer between your lips, inhaling a maximal breath then exhaling that breath a quickly as you can. The spirometer then records the amount and the rate of air that you breathed in and out over a period of time.
Since the test involves some forced breathing and rapid breathing, you may have some temporary shortness of breath or light-headedness.
Lung function tests are done to:
- Diagnose certain types of lung disease (such as asthma, bronchitis, and emphysema)
- Find the cause of shortness of breath
- Measure whether exposure to chemicals at work affects lung function
- Check lung function before someone has surgery
It also can be done to:
- Assess the effect of medication
- Measure progress in disease treatment
Lung function testing is available upon client request or on a referral (77.3 kb) basis by your doctor.
