He has a 40 pack-year smoking history and he continues to smoke 5-6 cigarettes per day. He had a myocardial infarction 8 years ago and had undergone stent replacement for the same. His past history is also significant for chronic bronchitis for 5 years. He has had one exacerbation in the last 1 year treated with oral antibiotics. Auscultation reveals decreased breath sounds, bilaterally. Which of the following can you expect to be increased in this patient? A. Forced vital capacity (FVC) B. Forced expiratory volume 1 (FEV1) C. FEV1 /FVC ratio D. Functional residual capacity
