PULMONARY FUNCTION TESTING

What Is A Pulmonary Function Test?

A pulmonary function test, (or PFT) is a non-invasive diagnostic test that provides measurable feedback about the function of the lungs. By assessing lung volumes, capacities, as well as rates of flow and gas exchange; PFTs provide information that can help diagnosis certain lung disorders when evaluated by your doctor.

Asthma
COPD
Interstitial Lung Disease

Chronic Cough
Sleep Apnea
Sarcoidosis
