Patient Forms
Pulmonary Function Tests (PFT)
Pulmonary Function Tests (PFTs) are a group of non-invasive tests that show how well your lungs are working. These tests are crucial in diagnosing lung conditions like asthma, COPD, and pulmonary fibrosis.
They also help doctors assess how a disease is progressing and how well treatments are working. If you experience chronic cough, breathlessness, or wheezing, your provider may recommend a PFT to better understand your lung health.

What Does a PFT Tell Us?
PFTs reveal how much air your lungs can hold, how quickly you can move air in and out, and how well oxygen transfers into your bloodstream. These results help paint a complete picture of your respiratory function and guide personalized care plans.
Types of Pulmonary Function Tests
Spirometry
Measures how much air you can exhale and how quickly. It helps diagnose conditions like asthma and COPD.
Lung Volume Testing
Assesses the total amount of air your lungs can hold, including the air left after full exhalation.
Diffusion Capacity (DLCO)
Determines how efficiently oxygen moves from your lungs into your bloodstream.
Why PFTs Matter in Your Care
Pulmonary function tests are more than just numbers—they guide real decisions in your health journey.
Track Disease Progression
Regular testing monitors how your lung condition is changing over time.
Guide Treatment Plans
