Dr. Hernandez treats adult patients with diseases of the respiratory system, but his primary areas of concern are diseases of the lungs and bronchial tubes. He often works with other physicians in providing care for patients with severe medical problems in the hospital. Historically, pulmonary physicians treated infectious diseases (i.e. tuberculosis), but chronic obstructive pulmonary disease (COPD), emphysema, bronchitis, and lung cancer have become more common. Dr. Hernandez's practice of pulmonary diseases also includes problems of blood circulation through the lung (i.e. blood clots), immunologic diseases (i.e. asthma), chest trauma, respiratory failure, treatment of pulmonary hypertension, and occupational and environmental diseases of the lung.
