A 65-year-old man comes to the office due to worsening exertional dyspnea over the past 3 months. This past year, he has had 4 respiratory infections that improved with medical therapy. He does not use alcohol or illicit drugs and has smoked 1 1/2 packs of cigarettes daily for 30 years. Temperature is 36.7 C (98.1 F), pulse is 76/min, and respirations are 18/min. On physical examination, breath sounds are diffusely decreased. Chest radiography reveals flattened hemidiaphragms, increased radiolucency of the lungs, and a long, narrow heart shadow. This patient's pulmonary function testing will most likely show which of the following patterns (total lung capacity; FEV1/FVC ratio; forced vital capacity; residual volume)?
