crackle

crackle

a common, abnormal respiratory sound consisting of discontinuous bubbling noises heard on auscultation of the chest during inspiration. Fine crackles have a popping sound produced by air entering distal bronchioles or alveoli that contain serous secretions, as in congestive heart failure, pneumonia, or early tuberculosis. Coarse crackles may originate in the larger bronchi or trachea and have a lower pitch. Crackles are not cleared by coughing. Formerly called rale. Compare rhonchus, wheeze. See also coarse crackle.

crac·kle

(krak'ĕl)
Short, sharp, or rough sounds heard with a stethoscope over the chest. Abnormal breath sounds caused by excessive fluid within the airways.
