What sound is associated with fluid in the alveoli?

Explanation:
Fluid in the alveoli produces crackles. As air moves into fluid-filled tiny airways and alveoli during inspiration, the small airspaces snap open, creating brief, discontinuous popping sounds known as crackles or rales. This is a hallmark of alveolar or interstitial involvement, such as pulmonary edema from heart failure or pneumonia with fluid in the alveoli. Wheezes are musical sounds from narrowed airways due to bronchospasm or edema, not alveolar fluid. Stridor is a high-pitched sound from upper airway obstruction. Rhonchi are low-pitched, coarse sounds from secretions in larger airways. So crackles best fit a scenario with fluid in the alveolar spaces.
