Pulmonary Function Testing (PFT)

Pulmonary Function Testing (PFT)

Pulmonary function testing is a group of breathing tests that measure how well your lungs work. PRN MEDICAL offers PFT as one of its services in Brooklyn, giving patients a clear, objective look at their breathing when symptoms or questions come up.

What PFT Measures

These tests are generally painless and involve breathing into a device in specific ways. Depending on the test, they can look at:

• Airflow — how much air you can breathe out, and how quickly.
• Lung volume — how much air your lungs can hold.
• Gas exchange — how well oxygen moves from the lungs into the blood.

When Patients Seek Testing

People commonly look into PFT for ongoing concerns such as:

• Shortness of breath — especially when the cause is not clear.
• Persistent cough or wheezing — symptoms that last or keep returning.
• Known lung conditions — such as asthma or COPD, where testing helps track how the lungs are doing over time.

Care Built Around You

Test results are most useful when they are read alongside your symptoms and health history. Dr. Yana Ryzhakova provides personalized, whole-person care built on thoughtful evaluation and clear communication, so you can understand your options and make informed decisions about your health.
