Dyspnea, not a productive cough, is the most common presenting factor of emphysema.
Neither cyanosis nor cor pulmonale is a common presenting factor of emphysema.

Chronic bronchitis is defined by hypersecretion of thick mucus. Ventilation-perfusion mismatch may occur, but chronic bronchitis is defined as hypersecretion of mucus. Neither hyperventilation nor thinning of smooth muscle occurs.
