Question

Quizplus · Accepted Answer

Wheezing is a musical, squeaking or whistling sound that is typically heard on expiration, but can also be heard on inspiration. Crackles, also known as rales, are a series of brief, discontinuous, non-musical sounds heard during inspiration. Stridor is a high-pitched, noisy breathing sound caused by disrupted airflow in the upper airway. Rhonchi are low-pitched, snoring or rattling sounds heard during inspiration and expiration caused by airflow through the bronchial tubes.
