Bronchial Sounds ans: Heard above the manubrium over the trachea. Usually harsh, high-pitched and
loud.
Bronchovesicular Sounds ans: Heard over the main bronchi and are usually of medium loudness, and
deeper pitch than bronchial sounds.
Vesicular Sounds ans: Heard over the lower bronchi, bronchioles, and lobes.
How many lobes does the left lung have? ans: 2 lobes
How many lobes does the right lung have? ans: 3 lobes
Decreased Breath Sounds ans: These sounds occur with airway disease or obstruction, diaphragm
paralysis, or impairment of sound transmission through the chest wall. No sounds usually mean that no
air is moving.
Increased Breath Sounds ans: These are common abnormal findings with bronchial or bronchovesicular
sounds which are louder or harsher and in peripheral lung tissue where vesicular sounds normally are.
This can occur when the underlying lung tissue is filled with liquid or solid material rather than air.
Adventitious Sounds ans: Sounds you hear in addition to normal sounds.
Fine Crackles ans: An adventitious sound that is faintly crackling and usually found at the base of lobes.
Course Crackles ans: An adventitious sound that is loud and low-pitched bubbling sounds when air
meets secretions in the larger airways.
Rhonchi ans: An adventitious sound that is continuous, low-pitched, snoring sounds that are caused by
airway obstruction from thick mucous secretions, muscular constriction or masses. Sounds like long
snoring sounds, low-pitched and found in the bronchi. Can sound like snoring or moaning.
Wheezes ans: An adventitious sound that is a continuous, high-pitched sound created by the narrowing
of airways from swelling, secretions, or masses. Sounds like long musical sounds, high-pitched and can
be found in all lung areas.
Stridor ans: An adventitious sound that is a loud, continuous, high-pitched crowing that is caused by
upper airway obstruction and is a MEDICAL EMERGENCY. Sounds like long crowing sounds, high-pitched,
comes from trachea, and is usually audible without a stethoscope.
