On chest examination for pneumonia, percussion is typically what?

Percussion findings reflect how much air is in the underlying lung. Healthy lungs sound resonant because they’re full of air. In pneumonia, the airspaces in the affected area are filled with inflammatory exudate, making the tissue denser and less air-filled. That increased density produces a dull (often described as flat to dull) percussion note over the consolidation. It’s not hyperresonant (seen with extra air, like in emphysema or pneumothorax) and not tympanic (often due to large air-filled spaces). So dullness to percussion over the involved region is the typical finding in pneumonia.
