There are many specialized fields that doctors can pursue after their Internal Medicine residency. In this episode, Dr. Roberto Swazo talks about his path to Pulmonary and Critical Care. This specialized field focuses on patients suffering from injuries and diseases of the respiratory system, which includes the lungs, trachea, diaphragm, and other related structures. At the time of our conversation, Dr Swazo was a Second Year Pulmonary and Critical Care Fellow, at Indiana University. He has since completed the fellowship and is now a Cardiac Intensivist and Pulmonary Hypertension Specialist, at Orlando Health.
