Pulmonary Function Tests (PFTs) are a group of tests that provide an extensive measure of lung volumes and flowrates, providing information on how well the lungs work.
Pulmonary Function Tests (PFTs) are a group of tests that measure how well your lungs work. These tests are done if you have a respiratory disease to see if you are responding to treatment or to diagnose a respiratory condition. PFTs can help diagnose conditions like asthma, COPD, and lung cancer.
Wear loose fitting comfortable clothing for your test. If you take medications for asthma or bronchitis that open your airways you should NOT take these before your test. Your doctor will tell you which of your medications you should or should not take before this test; make sure you tell your doctor if you are taking any over-the-counter medications. Avoid eating a large meal or consuming caffeine before your test. You should not smoke prior to your test.
Pulmonary Function Testing includes two different tests, spirometry and plethysmography.
