ADVENTITIOUS BREATH SOUNDS - EXAM 3 Flashcards
Discontinuous Sounds
Crackles (fine)
rackles (coarse
Continuous Sounds
Pleural friction rub
Wheeze (sibilant)
Wheeze (sonorous)
High-pitched, short, popping sounds heard during inspiration and not cleared with coughing; sounds are discontinuous and can be simulated by rolling a strand of hair between your fingers near your ear.
Crakles - fine
Low-pitched, bubbling, moist sounds that may persist from early inspiration to early expiration; also described as softly separating Velcro.
Crackles (coarse)
Low-pitched, dry, grating sound; sound is much like crackles, only more superficial and occurring during both inspiration and expiration.
pleural friction rub
High-pitched, musical sounds heard primarily during expiration but may also be heard on inspiration.
Wheeze
sibilant
itched snoring or moaning sounds heard primarily during expiration but may be heard throughout the respiratory cycle. These wheezes may clear with coughing.
Wheeze
sonorous
Associated conditions - regarding Crackles (Fine)
occurring late in inspiration are associated with restrictive diseases
- pneumonia and -congestive heart failure.
- Crackles occurring early in inspiration are associated with obstructive disorders such as bronchitis, asthma, or emphysema.
Associated conditions - regarding Crackles (Course)
- May indicate pneumonia, pulmonary edema, and pulmonary fibrosis.
- “Velcro rales” of pulmonary fibrosis are heard louder and closer to stethoscope, usually do not change location, and are more common in clients with long-term COPD.
Associated conditions -Pleural friction rub
Pleuritis
Associated conditions -Wheeze
sibilant
Sibilant wheezes are often heard in cases of acute asthma or chronic emphysema.
Associated conditions- Wheeze
sonorous
heard in cases of bronchitis or single obstructions and snoring before an episode of sleep apnea.
Stridor
harsh, honking wheeze with severe broncholaryngospasm, such as occurs with croup.
