The physical signs of this condition are the following: Percussion usually clear, but not unfrequently less so than natural, although very seldom quite dull. Auscultation detects coarse mucous or gurgling rhonchi, increased by the cough, combined with, or replaced by, bronchial or cavernous respiration, which is often effected as if by a sudden puff or whiff. The resonance of the voice is increased, but it seldom amounts to perfect pectoriloquy. The most common situations for dilated bronchia are the scapular, mammary, or lateral regions. They are almost always confined to one side.
