Bronchovesicular are auscultated in the posterior chest between the scapula. These are normal sounds in the mid-chest area or in the posterior chest between the scapula. Inspiration to expiration periods are equal with bronchovesicular lung sounds. They reflect a mixture of the pitch of the bronchial breath sounds heard near the trachea and the alveoli with the vesicular sound. They have an I:E ratio of 1:1.




These are abnormal in the lung periphery and may indicate an early infiltrate or partial atelectasis.
