What Are Abnormal Sounds

Abnormal breath sounds include: the absence of sound and/or. the presence of “normal” sounds in areas where they are normally not heard. For example, bronchial (loud & tubular) breath sounds are abnormal in peripheral areas where only vesicular (soft & rustling) sounds should be heard.

What are abnormal Bronchovesicular sounds?

Bronchial sounds are due to air moving through the large bronchi and trachea and are heard best on expiration. Bronchovesicular sounds are the combination of the above two and are heard best over the hilar area. • Abnormal respiratory sounds include attenuated sounds as well as increased, abnormal sounds.

What are the normal lung sounds?

• Loud, high-pitched bronchial breath sounds over the trachea.
• Medium pitched bronchovesicular sounds over the mainstream bronchi, between the scapulae, and below the clavicles.
• Soft, breezy, low-pitched vesicular breath sounds over most of the peripheral lung fields.
