It is a unit designed to prevent and diagnose respiratory diseases, to make the necessary interventions, and to provide lung rehabilitation, which will enable patients suffering from respiratory diseases to lead healthy and productive lives. The latest technology is used to provide sophisticated treatment in both outpatient and hospital settings, including intensive care units.

The Department of Pulmonology has state-of-the-art outpatient and inpatient facilities with support from the Intensive Medical Care Unit (IMCU) and excellent operating theatre facilities for thoracic surgery.
