What does the “breathing test” tell you?
A Pulmonary Function Tests (PFT) measure how well the lungs take in and exhale air. A complete PFT is done to diagnose the type of lung disease.
It is a test that lasts approximately 45 minutes. Breathing measurements are taken as you do several different types of breathing, such as panting and slow, deep breathing. This test is done initially for diagnosis.
Spirometry, a simple quick test measures 3 good breaths and is done in the office to monitor changes in lung function over time. This test is done routinely as well as when medication changes are made or breathing problems flare up.
