The percussion tone of hyperresonance is heard with emphysema related to overinflation of the lung. Resonance can be found in normal lungs or with the diagnosis of bronchitis. Tympany occurs with the diagnosis of large pneumothorax and emphysematous blebs. Dullness occurs with the diagnosis of atelectasis, pleural effusion, pulmonary edema, pneumonia, and a lung mass.
