What is a common exam finding in emphysema?

• A. Increased tactile fremitus
• B. Dullness to percussion
• C. Hyperinflation of the lungs
• D. Deviated trachea

Answer: (C)

Hyperinflation of the lungs is a hallmark finding in emphysema due to the destruction of alveolar walls, which reduces elastic recoil and leads to air trapping. This condition arises from prolonged airflow obstruction, thereby causing an increase in lung volume and flattening of the diaphragms on imaging studies. Clinically, hyperinflation can manifest as a barrel-shaped chest due to the expansion of the thoracic cavity over time. As patients with emphysema breathe, they may demonstrate a prolonged expiratory phase in their breath sounds, further indicating the pathophysiology associated with this condition. This finding is significant as it reflects the degree of lung involvement and guides management strategies for individuals suffering from emphysema.
