AUDIO 9-11.

From: Current Medical Diagnosis & Treatment 2017

Breath sound from a patient with severe long-term chronic obstructive lung disease. The patient was in respiratory distress because of a cyst on his larynx, causing stridor. The stridor can be distinguished by the inspiratory extenuation of the higher pitched continuous noise.
