A 72-year-old man presents to the ED with worsening dyspnea. His initial vitals include a HR of 93 beats per minute, BP of 110/50 mm Hg, and RR of 20 breaths per minute with an oxygen saturation of 88% on room air. The patient appears thin and anxious. He is using accessory muscles to breathe. Despite distant breath sounds, you hear end-expiratory rhonchi and a prolonged expiratory phase. An ECG shows peaked P waves in leads
II, III, and aVF. Given this patient’s history and physical examination, which of the following conditions does this patient most likely have?
a. Chronic bronchitis
b. Asthma
c. Emphysema
d. Congestive heart failure (CHF)
e. Pneumothorax
