| Lung Function Tests : What are lung function tests? Lung function tests are a group of tests that check how well your lungs are working. These tests are also called pulmonary function tests, or PFTs. They may be used with other tests and information to help diagnose and monitor certain lung diseases. There are many types of lung function tests. Most of them involve breathing through a mouthpiece. The mouthpiece is connected to a device that makes different types of measurements, such as: - How much air your lungs can hold - How well you move air in and out of your lungs when you breathe - How well your lungs absorb oxygen from the air you breathe and move it into your blood Lung function tests also help check the health of your airways. Your airways are the parts of your body that carry air to your lungs, including your nose, throat, trachea (windpipe), and bronchial tubes that connect your windpipe to each lung. Common lung function tests include: - Spirometry. This lung function test is used the most. A spirometry test measures how much air you breathe out and how fast you can blow air out of your lungs. - Lung volume test, also called as body plethysmography. This test is the most accurate way to measure the amount of air your lungs can hold. It also measures the amount of air that remains in your lungs after you exhale as much as you can. - Lung diffusion capacity test. This test measures how well your lungs deliver oxygen to your blood from the air you breathe. - Exercise tests. There are different types of tests that measure how well your lungs work when you are active, including:Six minute walk testCardiopulmonary (heart and lung) exercise test (CPET) Your health care provider may order one or more lung function tests, depending on the reason you need to be tested.
