What is this lung sound?
|
Crackles (These crackles and bronchial breathing were recorded posteriorly over the consolidated left lower lung of a 16 year old boy with tuberculosis)
What do crackles signify? |
Crackles are caused by the "popping open" of small airways and alveoli collapsed by fluid, exudate, or lack of aeration during expiration. The word "rales" derives from the French word râle meaning "rattle".
Crackles can be heard in patients with pneumonia, atelectasis, pulmonary fibrosis, acute bronchitis, or bronchiectasis. Pulmonary edema secondary to left-sided congestive heart failure can also cause rales. |
