Normal lung sounds Bronchial, bronchovesicular, vesicular You can hear _______ sounds above the manubrium, over the trachea. These sounds are: -Harsh -High-pitched -Loud Bronchial ________ sounds are heard over the main bronchi. These sounds are: -Medium in loudness -Medium in pitch Bronchovesicular _______sounds are heard over the lower bronchi, the bronchioles, and the lobes. The left lung has two lobes. The right lung has three lobes. -Softest -Lowest in pith Vesicular Abnormal lung sounds -Diminished or absent breath sounds -increased breath sounds -adventitious sounds Decreased breath sounds Normal lung sounds are usually easy to hear with a stethoscope. Occasionally you will hear sounds that are decreased in intensity, or even absent. Decreased breath sounds occur in airway disease or obstruction, diaphragm paralysis, or impairment of sound transmission through the chest wall. Worsening symptoms may lead to absent breath sounds. Absent lung sounds usually indicate that no air is moving in the lung tissue. Increased breath sounds Location of breath sounds matters! A "normal sound" is not normal if it is in the wrong place. A common abnormal finding is hearing bronchial or bronchovesicular sounds, which are louder and harsher, in peripheral lung tissue where vesicular sounds are normally heard. This occurs when underlying lung tissue is filled with liquid or solid material, rather than air. Adventitious sounds When you auscultate, you might hear abnormal sounds in addition to the normal lung sounds. These additional abnormal sounds are called adventitious sounds.
