A hemothorax typically presents with what percussion note?

Fluid in the pleural space from a hemothorax makes the area sound dull when tapped. Percussion differences come from what’s under the surface: air in the lungs gives a resonant sound, fluid in the pleural space muffles and reduces sound, producing dullness. A pneumothorax, with air accumulating, tends to produce a hyperresonant sound, while a normal chest is resonant. If the effusion is large, the dullness may spread to the lower chest and can shift with position. So the expected percussion note for a hemothorax is dull to percussion.
