Question

Quizplus · Accepted Answer

A dull percussion note is typically heard in conditions where the lung or pleural space is filled with something other than air, such as fluid or solid tissue. This occurs in atelectasis (collapse of lung tissue), pleural thickening (thickening of the tissue layers surrounding the lungs), and consolidation (solidification of lung tissue due to accumulation of fluid and cells, often seen in pneumonia). Chronic obstructive pulmonary disease (COPD), on the other hand, is characterized by airway obstruction and hyperinflation of the lungs, which would more likely lead to a hyperresonant percussion note rather than a dull one.
