What would you like to know about pulmonary function tests?
Pulmonary function tests are key tools doctors use to diagnose and monitor COPD. The most common test is spirometry, which measures how well your lungs are working.
During spirometry, you'll breathe into a tube as hard as you can. The device measures two important things:
- How much air you can blow out in the first second (FEV1)
- The total amount of air you can exhale when you fully empty your lungs (forced vital capacity)
These measurements help your doctor determine if you have COPD and how severe it is. The results guide your treatment plan and can be used over time to track how your condition is progressing.
Other tests you might encounter include:
- Peak expiratory flow test: Measures how fast you can blow air out using a handheld device
- Diffusing lung capacity (DLCO): Checks how well your lungs exchange oxygen and carbon dioxide
These tests are painless and give your healthcare team valuable information about your lung function. They're also useful for monitoring your COPD after diagnosis to see if treatment adjustments are needed.
