Crackles are most commonly heard in which condition?

Crackles come from air trying to move through fluid or reopening small airways that have collapsed. The scenario where this sounds happen most repeatedly and broadly is pulmonary edema from heart failure. Fluid accumulates in the interstitium and alveoli, so as you inhale the air moves through that fluid and the small airways pop open, creating fine crackles, typically heard at the lung bases on inspiration. This diffuse, bilateral basilar crackling is more characteristic of edema than the other listed conditions, which can produce crackles but usually in more localized areas or in different lung sounds and patterns.
