A pulmonary lung function test is a non-invasive way to determine how well your lungs are working. The test measures your lung capacity, airflow, volume, and how much oxygen and carbon dioxide are exchanged when you are breathing in and out. This test also provides other vital information your doctor needs, such as the condition of your abdominal muscles and diaphragm, or how well your alveoli are functioning, in order to diagnose any underlying condition.
Pulmonary function tests can help the doctor rule out other issues such as neurological or muscular conditions that may be a sign of a progressive illness that indirectly affects your ability to breathe. You may also be asked to take several other tests, such as a cardiac stress test, X-rays, a SHAPE ((Sub-maximal Heart and Pulmonary Evaluation), a six-minute walking test, or a spirometry, a test that measures the volume and speed of your expelled air.
More About Pulmonary Function Tests
There are a few different kinds of pulmonary function tests. At Lung and Sleep Specialists of North Texas, we have a comfortable, customized clear room with a breathing machine that our patients use during the testing. Most pulmonary function tests require about 45 min to an hour to complete, depending on what other tests, if any, your doctor wishes to include.
A pulmonary function test can also pinpoint issues such as:
· Problems with the bronchial tubes
· Conditions affecting the voice-box (larynx) and or windpipe (trachea)
· Poor air condition between the alveoli (tiny air sacs of the lungs)
· Asthma and other breathing disorders
There is no special preparation required for a pulmonary function test, although you may wish to consider dressing comfortably. You should also avoid wearing anything constricting, such as a tight belt that restricts your ability to breathe deeply. Your doctor may advise you to take any prescribed breathing medications prior to the pulmonary lung function test. Although you may feel slightly tired after the test, you should be able to resume your normal activities immediately following the test.
