A 60-year-old man presents to your office with a prescription of functional decline. The patient complains of frequent coughing and shortness of breath (SOB). He is well known to you because of multiple office visits in the past few years for similar reasons. He has a chronic “smoker’s cough,” but reports that in the past 2 days his cough has increased, his sputum has changed from white to green in color, and he has had to increase the frequency with which he uses his Albuterol inhaler. He denies having a fever, chest pain, peripheral edema, or other symptoms. His medical history is significant for hypertension, peripheral vascular disease, and two hospitalizations for pneumonia in the past 5 years. He has a 60-pack-year history of smoking and continues to smoke two packs of cigarettes a day. Patient reports decreased ability to walk inside his home and difficulty with all ADLs due to fatigue and SOB. He denies having any assistive device at home and denies use of supplemental O2.

On examination, patient appears with barrel chest. He is in moderate respiratory distress. His temperature is 98.4°F, his blood pressure is 152/95 mm Hg, his pulse is 98 beats/min, his respiratory rate is 24 breaths/min, and he has an oxygen saturation of 91% on room air at rest. His lung examination is significant for diffuse expiratory wheezing, use of accessory muscles of respiration and a prolonged expiratory phase of respiration. There are no signs of cyanosis. Patient presents with impaired strength in bilateral LEs. Endurance is impaired and by demonstrated a decreased 2MWT with increased, tachycardia, tachypnea, and decreased O2 saturation after performance requiring 5 min to recover. Patient presents with increased labor of breathing after minimal activity. Patient requires increased time for bed mobility, transfers, and gait with multiple rest breaks. A chest X-ray shows an increased anteroposterior (AP) diameter and flattened diaphragms, but otherwise he has clear lung fields.3
