| The Pulmonologist diagnoses and treats pneumonia, pleurisy, asthma, occupational diseases, bronchitis, sleep disorders, emphysema, and other complex disorders of the lungs. Pulmonologists test lung functions in many ways, endoscope the bronchial airways if necessary, and prescribe and monitor mechanical assistance to ventilation. |  | Greg Hicklin, M.D.
