Understand LUNG SOUNDS In Less Than A Minute

Rales (or crackles) are abnormal lung sounds heard during inhalation, often associated with fluid in the airways or alveoli, and can indicate conditions like pneumonia or heart failure.

Rhonchi are coarse, rattling sounds, usually caused by mucus or obstructions in the larger airways, often heard in conditions like bronchitis or later stage pneumonia.

Wheezing is a high-pitched whistling sound that occurs when air flows through narrowed airways, commonly seen in asthma or COPD.

Stridor is a harsh, high-pitched sound typically heard during inspiration and is a sign of upper airway obstruction, often caused by conditions like croup or a foreign body.
