Pulmonary Function Testing (PFTs) is a comprehensive series of non-invasive tests to objectively measure how well the lungs are working. The tests measure lung volumes, rates of flow, and gas exchange. Most common tests include Spirometry, diffusion capacity(DLCO), and body plethysmography. Sometimes only one test is performed, other times all the tests may be completed.
The tests will provide the following information:
-
Assist in making a diagnosis of various chronic conditions of the respiratory system,
-
Compare the lung function of the person to their predicted values, showing how well the lungs should be working in a healthy person,
-
Identify changes in lung function that require treatment or intervention
-
Decide which medicine would be helpful to alleviate respiratory symptoms
-
Determine the patient’s ability to tolerate surgical procedure or treatment
-
Evaluate the effectiveness of the current treatment
