Spirometry measures how well your lungs are working, and doctors often use it in the diagnosis of respiratory diseases. If you've never had spirometry, you may have questions about what it is, how you need to prepare for it, and what the results mean.
Spirometry measures how well your lungs are working by measuring how much air you can inhale, how much air you can exhale, and how fast you can breathe out. The test can help diagnose respiratory conditions and monitor how well a specific treatment is working. In addition, it can determine the progression and severity of respiratory conditions.
