Normal Lung Sounds. Normal breath sounds are classified as tracheal, bronchial, and vesicular sounds. The patterns of normal breath sounds are created by the effect of body structures on air moving through airway. Normal lung sounds can be considered abnormal when the sound occurs in an area in which the sounds should not be present.
This breath sound is abnormal if heard over the peripheral lung fields. Bronchial Breath Sound-a harsh, high pitch, low intensity breath sound with expiration longer than inspiration (I<E) (1:2). This sound is normal over the trachea but always considered abnormal if heard over the peripheral lung fields.
