A 150 lb., 63-year-old man is experiencing exertional dyspnea, shortness of breath, mild cyanosis, and marked slowing of forced expiration. He is chronically fatigued from the action of breathing and appears to have a "barrel chest." In addition, he has been a smoker for 40 years. The doctor describes his condition as a "progressive disease that directly affects the site of gas exchange in his lungs."
What is the disorder of this man? Be as specific as possible. (Hint: more specific than "COPD").
Diagnosis : Emphysema
63 yr old man with history of chronic smoking, with dyspnea, mild cynosis, and marked slowing of forced expiration and Barrel shaped chest are all suggetive of emphysema.
Emphysema is a type of chronic obstructive airway disease caused due to permanent dilatation of airway distal to terminal bronchole. It leads to air trapoing, hyperinflation of lungs and hence barrel shape chest wall.
