Pulmonologists are medical doctors who further specialize in the diagnosis and treatment of lung disease, such as asthma, emphysema, or pneumonia. Pulmonologists perform tests to check how well a person is breathing. And they may use procedures such as bronchoscopy to diagnose a breathing problem.

Pulmonologists can be board-certified through the Board of Internal Medicine, which is recognized by the American Board of Medical Specialties.
