Which of the following is a common sign of emphysema?

Emphysema causes air trapping and lung hyperinflation, so the chest often takes on a barrel-shaped appearance as the lungs stay inflated and the rib cage sits in a more expanded position. This hyperinflation makes breathing work harder, so people commonly experience shortness of breath with routine activities due to increased work of breathing and reduced elastic recoil. Cyanosis tends to appear later, indicating more advanced oxygen deficiency, while a frequent productive cough is more tightly linked to chronic bronchitis, where mucus production is a prominent feature of the disease. So, while shortness of breath with normal activities and a barrel-shaped chest are typical signs of emphysema, a frequent productive cough points more toward chronic bronchitis.
