Which is a classic sign of emphysema?

Barrel-shaped chest develops from hyperinflation caused by loss of elastic recoil and persistent air trapping in emphysema. As the lungs stay chronically inflated, the anterior-posterior diameter increases, giving that rounded, “barrel” appearance. This physical change is a hallmark of emphysema and reflects the core airflow limitation from destroyed alveolar walls. Other signs you might see aren’t as specific to emphysema. A productive cough with sputum points more toward chronic bronchitis. Orthopnea (shortness of breath when lying flat) is typically related to heart failure or fluid overload. Cyanosis of the nails or lips indicates significant hypoxemia, a sign that can appear with advanced disease but isn’t the classic descriptor of emphysema itself.
