Upon thoracic examination, patients with obstructive lung disease have diffuse wheezing, hyperinflation (barrel chest), diffusely decreased breath sounds, hyperresonance upon percussion, and prolonged expiration.

Coarse crackles beginning with inspiration may be heard, and wheezes frequently are heard upon forced and unforced expiration. Cyanosis may be noted if accompanying hypoxia is present. Clubbing may be present.
