Harsh, High-pitched, Loud ans: You can hear bronchial sounds above the manubrium, over the trachea.
Bronchial Sounds are:
Medium in loudness, medium in pitch ans: Bronchiovesicular sounds are heard over the main bronchi.
These sounds are:
Softest, lowest in pitch ans: vesicular sounds are over the lower bronchi, the bronchioles, and the lobes.
The left lung has two lobes. The right lung has three lobes.
Right lung ans: 3 lobes: Vesicular Right Superior, Vesicular Right Middle,Vesicular Right Inferior.
Left lung ans: 2 lobes: Vesicular Left Superior & Vesicular Left Inferior
Abnormal lung sounds ans: Diminished or absent breath sounds, increased breath sounds, &
adventitious sounds.
Decreased Breath Sounds ans: Normal lungs sounds are usually easy to hear with a stethoscope.
Occasionally you will hear sounds that are decreased in intensity, or even absent. Decreased breaths
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 ans: A common abnormal finding is hearing bronchial or bronchiovesicular
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 ans: 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) ans: High-pitched crackling sounds that occur when inhaled air meets deflated alveoli,
causing them to pop open. Short popping sounds, high-pitched, Location: usually bases of lower
lobes.Sound like the noise created by rolling a strand of hair between your thumb and index finger.
(likely Pneumonia)
Crackles (Coarse) ans: loud, low-pitched bubbling sounds that are caused when air meets secretions in
the large airways. Short crackling sounds, low-pitched, Location: trachea and large bronchi. Sounds like
separating a Velcro fastener.
Ronchi ans: Continuous, low-pitched snoring sounds caused by airway obstruction from thick secretions,
muscular constriction, or masses. Long snoring sounds, low-pitched, Location: Bronchi. Sounds likes
snoring or moaning.
Wheezes ans: continuous, high-pitched musical sounds that are created by the narrowing of airways
from swelling, secretions, or masses. Long musical sounds, high-pitched, Location: all lung fields.
