Pulmonary Function Testing

Pulmonary function testing is used to diagnose and monitor asthma, COPD (emphysema and chronic bronchitis) and other lung disorders. These tests are used to monitor patient response to treatment regimens prescribed by our physicians.

Each pulmonary function test evaluates a different aspect of lung function, such as how quickly air can move in and out of the lungs, how much air they can hold and how well lungs function during exertion.

testing your lungs

A specialist will apply a mask or mouthpiece to the patient, which is attached to a device called a spirometer.

In some cases, a nose clip is connected to the mouthpiece to prevent air from leaking out. As the patient breathes in and out, the spirometer analyzes lung capacity and function. Our specialist will ask each patient to breathe in different ways to achieve a full assessment of lung function.

Patient’s may feel dizzy or lightheaded during testing, but stress levels are being closely monitored throughout the evaluation for signs of stress.


Values and results vary from person to person. Patients results are carefully analyzed, then compared to an average of results from patients of a similar background, body composition, and age. Testing gives us a general assessment of lung health and helps medical providers at Louisiana Internal Medicine & Pediatric Association make educated decisions regarding treatment for patients.


Pulmonary TestingTips

There are several items and activities patients must avoid 24 hours before testing. Patients should not smoke for at least one hour before testing, and avoid any alcoholic substances for at least four hours before the test. Avoid heavy exercise for at least 30 minutes before testing. Patients should wear loose fitting clothing to ensure they won’t have any difficulty breathing. Also, patients should avoid ingesting a large meal within two hours before testing. Check with your doctor for any additional instructions.
