Which COPD type is described as pink coloration with barrel chest and pursed-lip breathing, often called pink puffers?

Which COPD type is described as pink coloration with barrel chest and pursed-lip breathing, often called pink puffers?

• A. Chronic Bronchitis
• B. Emphysema
• C. Bronchiectasis
• D. Asthma

Answer: (B)

The description points to emphysema. In emphysema, destruction of alveolar walls and loss of elastic recoil cause air trapping and lung hyperinflation, giving a barrel-shaped chest. To keep airways open during expiration, patients adopt pursed-lip breathing, which is a classic sign of this phenotype. Oxygenation can be relatively preserved early on, so the skin may stay pink rather than cyanotic, hence the term “pink puffer.” Chronic bronchitis, in contrast, produces a blue-tinged appearance with a productive cough and often edema and weight gain, not the lean, barrel-chested pink profile. Bronchiectasis involves chronic productive sputum and recurrent infections, while asthma features reversible obstruction with wheeze rather than the marked hyperinflation and pursed-lip breathing typical of emphysema.
