What is another term for crackles?

Explanation:
Crackles are also called rales. This term describes discontinuous, brief, nonmusical sounds heard with a stethoscope as air moves through small, fluid-filled airways. They often indicate fluid in the alveoli or small airways and can be heard in conditions like congestive heart failure with pulmonary edema, pneumonia, or interstitial fibrosis. They differ from wheezes, which are continuous high-pitched musical sounds from narrowed airways; rhonchi, which are lower-pitched, snoring sounds from secretions in larger airways; and a pleural rub, which is a grating sound from inflamed pleural surfaces. Understanding this helps you interpret auscultation findings and their possible causes.
