What is an abnormal respiratory sound heard on auscultation?

Breath sounds may be heard with a stethoscope during inspiration and expiration in a technique called auscultation. Abnormal lung sounds such as stridor, rhonchi, wheezes, and rales, as well as characteristics such as pitch, loudness, and quality, can give important clues as to the cause of respiratory symptoms.

What does fluid in lungs sound like?

Crackles are also known as alveolar rales and are the sounds heard in a lung field that has fluid in the small airways. The sound crackles create are fine, short, high-pitched, intermittently crackling sounds. The cause of crackles can be from air passing through fluid, pus or mucus.
