Assessing Lung Sound

To auscultate lung sounds, move the diaphragm of your stethoscope according to the numbers on the corresponding diagram.

There are three normal breath sounds :

• (B) Bronchial Breath Sounds - loud, harsh, hight pitched
  Heard over trachea, bronchi (betwen clavicles and midsternum), and over main bronchus.


• (BV) Bronchovesicular Breath Sounds - blowing sounds, moderate intensity and pitch.
  Heard over large airways, on either side of sternum, at the Angle of Louis, and betwen scapulae.


• (V) Vesicular Breath Sounds - soft breezy quality, low pitched.
  Heard over the peripheral lung area, heard at best of base lungs.
