At Kingwood Pulmonary, PA, the team offers three different types of pulmonary function testing:
Spirometry
Spirometry is a type of pulmonary function test that measures the amount of air you breathe in and out. During this type of test, your provider asks you to breathe in and out as quickly or as deeply as you can for several seconds. They might also ask you to perform the test after taking a bronchodilator, a medication that opens your airways.
Plethysmography test
A plethysmography test measures the amount of gas in your lungs, or lung volume. For this test, you stand in a small booth and breathe into a special mouthpiece. Your provider evaluates your individual measurements to learn more about your respiratory capacity.
Diffusion capacity test
A diffusion capacity test is a type of pulmonary function testing that measures how well your alveoli work. Ultimately, this test measures how well your lungs convert and transfer oxygen and carbon monoxide to and from your bloodstream.
