Diffuse crackles

Diffuse crackles are abnormal lung sounds characterized by a series of short, discontinuous, high-pitched sounds heard during inspiration, resulting from the sudden opening of small airways and alveoli. They are clinically significant as they indicate the presence of fluid in the alveolar spaces, commonly associated with conditions such as pneumonia or heart failure. Recognising diffuse crackles can aid in early diagnosis and management of respiratory distress in patients.
