Normal lung sounds - Answer bronchial, bronchovesicular, vesicular
You can hear _______ sounds above the manubrium, over the trachea. These sounds
are:
-Harsh
-High-pitched
-Loud - Answer Bronchial
________ sounds are heard over the main bronchi. These sounds are:
-Medium in loudness
-Medium in pitch - Answer 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 - Answer Vesicular
Abnormal lung sounds - Answer -Diminished or absent breath sounds
-increased breath sounds
-adventitious sounds
Decreased breath sounds - Answer 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 - Answer 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 - Answer When you auscultate, you might hear abnormal sounds in
addition to the normal lung sounds. These additional abnormal sounds are called
adventitious sounds.
Crackles(fine) - Answer Fine crackles, as the name indicates, are high-pithed crackling
sounds that occur when in haled air meets deflated alveoli, causing them to pop open.
