Spirometry (spy-ROM-uh-tree) is a common office test used to assess how well your lungs work by measuring how much air you inhale, how much you exhale and how quickly you exhale. Spirometry is used to diagnose asthma, chronic obstructive pulmonary disease (COPD) and other conditions that affect breathing.

What are the benefits of spirometry?

Spirometry can help tell if your breathing is affected by narrowed or inflamed airways. The results are useful in diagnosing lung conditions such as COPD and asthma. For some conditions, it can be used to grade how severe your condition is.

Can spirometer increase lung capacity?

Using an incentive spirometer teaches you how to take slow, deep breaths, and can be helpful to maximize lung capacity after surgery or when you have a progressive condition, such as lung disease. By using this device, you're taking an active step in your recovery and healing.
