Bronchoscopy is a procedure in which a physician uses a tube with a small camera to look inside the lungs’ airways and to take tissue or fluid samples. The procedure is used to diagnose a problem in the lungs, such as a tumor on an infection. There are two types of bronchoscope — the more frequently used flexible fiberoptic bronchoscope and the rigid bronchoscope.
Pulmonary Function Testing
Pulmonary function testing, or spirometry, measures how well the lungs are working. It is used to diagnose and evaluate patients with asthma, cystic fibrosis, lung cancer and other lung conditions.
