Cаse:A 64-yeаr-оld mаle presents tо the clinic with prоgressive shortness of breath and decreased exercise tolerance. He has a 45-pack-year smoking history. He reports a chronic productive cough for several years, producing thick sputum most mornings. On exam, he is mildly overweight, cyanotic, and has bilateral coarse rhonchi. His oxygen saturation on room air is 88%, and he demonstrates elevated CO₂ on venous blood gas. A second patient, age 71, also presents with exertional dyspnea. She has a 40-pack-year smoking history but denies chronic sputum production. On exam, she is thin, uses pursed-lip breathing, and has a barrel-shaped chest. Breath sounds are markedly diminished, and she reports difficulty maintaining weight. Question: Based on the clinical features above, differentiate the predominant COPD phenotype (chronic bronchitis vs Emphysema) exhibited by each patient and describe at least two key clinical characteristics that justify your classification.
