Lung Function Testing (also called pulmonary function testing) is a group of tests that measure how well your lungs work. These tests check how much air you can inhale and exhale, how quickly you can move air in and out, and how efficiently your lungs deliver oxygen to your blood. They are commonly used to diagnose and monitor conditions like asthma, chronic obstructive pulmonary disease (COPD), and other breathing disorders. The tests are simple, non-invasive, and may involve breathing into a special device called a spirometer. Results help doctors create or adjust treatment plans to improve your breathing and overall lung health.

Bellagio Family Medical, uses two main lung function tests.

Spirometry

During a spirometry test, you’ll follow your care provider’s directions to breathe into a small tube that’s connected to a spirometer machine.  Spirometry measures the amount of air you can inhale and exhale. This test also calculates how fast you exhale.

Exhaled nitric oxide testing

During an exhaled nitric oxide test, you’ll breathe using a measured and steady pace, exhaling into a tube connected to the test machine. Exhaled nitric oxide testing measures the level of nitric oxide gas inside your lungs.

You may have one or both tests, based on your condition or suspected condition. You may also need other lung function tests or other types of testing, like patch testing for allergies in some cases.

There’s typically no special preparation needed, and it’s usually fine to eat and drink before your lung function testing. Bronchodilators — medications that expand your airways — can alter the results of your test, so your allergist might ask you to avoid using that medication immediately before your testing. If you have any physical condition that affects your breathing, for example, if you’re pregnant and can’t breathe as deeply as usual, let your doctor know ahead of your testing.

Your Bellagio Family Medical, doctor calculates your results by comparing them to others in your age, height, and gender group. If you have any abnormal values, your doctor explains what they mean and how they help direct your treatment planning.
