Crepitation is defined as?

Explanation:
Crepitation is the crackling or rattling sound heard on auscultation of the lungs. It happens when air moves through fluid in the small airways or when alveoli pop open, producing fine or coarse crackles. This finding is commonly seen with conditions like pneumonia, pulmonary edema, or atelectasis. It’s not a muffled heart sound, not a high-pitched wheeze, and not a dull percussion note, which helps distinguish it from other chest findings.
