Coarse Crackles vs. Pleural Rub: Key Differences Explained

Discover the key differences between coarse crackles and pleural rub, crucial for diagnosing respiratory conditions.

27 views

Coarse crackles are low-pitched, wet lung sounds heard during inspiration, often caused by fluid in the airways from conditions like pneumonia or heart failure. Pleural rub, on the other hand, is a grating sound produced when the inflamed pleural layers rub against each other, usually due to pleuritis. Distinguishing these sounds helps in diagnosing respiratory issues accurately.
