In COPD, which breath-sound finding is typical?

In COPD the airflow limitation is mainly from airway obstruction and air trapping, which tends to reduce overall air entry and produce sounds that reflect narrowed airways on expiration. Diminished breath sounds indicate that less air is moving in and out of the lungs due to hyperinflation and mucus-related obstruction. The expiratory wheeze seen on both lungs arises from air trying to escape through narrowed, inflamed airways during expiration. Together, reduced aeration with bilateral expiratory wheeze is a classic auscultatory pattern in COPD. Clear breath sounds with normal air entry would be less consistent with COPD, dull percussion suggests consolidation or effusion, and hyperresonant percussion can occur with hyperinflation but doesn’t specify the characteristic expiratory wheeze and diminished air entry that COPD commonly shows.
