This is the definition of vesicular breath sounds. They are heard over the entire surface of the lungs, with the exception of the upper intrascapular area and the area beneath the manubrium. Bronchial breath sounds are heard only over the trachea near the suprasternal notch. Adventitious breath sounds are not usually heard over the chest. These sounds occur in addition to normal or abnormal breath sounds. Bronchovesicular breath sounds are heard over the manubrium and in the upper intrascapular regions, where the trachea and bronchi bifurcate.
