Vesicular breath sounds are the sounds heard during auscultation of the chest of a healthy person (listen to the audio recording below). The inspiratory component predominates and is generated by turbulent airflow within the lobar and segmental bronchi, whereas the expiratory component is due to flow within the larger airways.
Breath sounds are created when air moves in and out the respiratory tract. When you assess breath sounds you are assessing the pitch, intensity, quality and duration of the inspiration and expiration. The classification of normal breath sounds includes vesicular, bronchovesicular, bronchial, and tracheal.
Bronchial breath sounds are heard over the large bronchi (over the breastbone or sternum in the mid-chest region and between the shoulder blades on the back). They are higher-pitched and louder than breath sounds heard over other parts of the lungs, but quieter and more hollow-sounding (tubular) compared with tracheal breath sounds.
