Pulmonary function analyzers measure the respiratory performance of patients with suspected pulmonary disease. They provide objective data about the clinical status of a patient's lungs, such as ventilation, diffusion, and distribution of gases in the lungs.
A pulmonary function analyzer (PFT) is a noninvasive test that measures how well the lungs are working. The tests measure lung volume, capacity, rates of flow, and gas exchange. The most basic test is spirometry. During a spirometry test, you breathe into a mouthpiece that is connected to an instrument called a spirometer. The spirometer records the amount and the rate of air that you breathe in and out over a period of time. The diffusion capacity test evaluates how well the small air sacks inside the lungs, called alveoli, work.
The three main types of PFTs are: Spirometry Lung volume testing Lung diffusion capacity
