Which finding is characteristic of COPD general appearance?

Barrel-shaped chest results from chronic air trapping and lung hyperinflation in COPD. Over time, the lungs remain inflated and the chest expands more in the front-to-back (AP) diameter, giving a rounded, barrel-like appearance. The diaphragms flatten and the rib cage assumes a more horizontal, expanded position, which together produce that characteristic look. A flat chest isn’t typical of COPD and would suggest other conditions or restrictive changes. A normal chest diameter would imply little to no hyperinflation, which doesn’t match COPD’s outward appearance. Scoliosis alters spine alignment and chest shape for reasons unrelated to COPD, so it’s not the general appearance tied to this condition.
