Breath sounds + Percussion Flashcards
Stridor
An obstruction or narrowing in the upper airway, outside of the chest cavity
Loud, continuous, high pitched
Where is stridor located?
What does it indicate?
Heard over trachea usually during inspiration
Anaphylaxis, coup, tumor, edema
Increased tactile fremitus?
Lots of consolidation/hard surface
Causes:
lung tumor, pneumonia, atelectasis,
Decreased tactile fremitus
No vibrations
Causes:
due to a hollow area like pneumothorax, pleural effusion, hyperinflation, mucous plug
Hyperresonant percussion
Extra air
Pneumothorax or hyperinflation etc.
Hyporesonant percussion
Consolidation:
Pneumonia, tumor, atelectasis, pleural effusion
Bronchial breath sounds
Normal in large airways.
Harsh loud pitched sounds
[I] shorter than [E]
Bronchovesicular breath sounds
Moderate pitch
I:E = equal
located in central areas of the lung
Vesicular breath sounds
High pitch soft sounds
Normal in alveoli/peripheries of the lung
[I] longer than [E]
Rhonchi sound
Low pitched sound
Due to fluid or secretions in the large airway.
Pleural friction rub
continuous, dry grating sound caused by inflammation of pleural surfaces and loss of lubricating pleural fluid
Fine crackles
short high pitched sounds during inspiration, usually don’t clear with a cough,
Indictors of:
Discontinuous Atelectasis
interstitial fibrosis
pulmonary edema
Coarse crackles
ow pitched, continuous, may clear with cough
Indicators of:
COPD, CF, bronchiectasis, pulmonary edema
Cheyne-stokes
A breathing pattern with short panic periods.
