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.
