A member asked:
What would experts say about anatomical basis for the wheezing heard during an asthma attack?
A doctor has provided 1 answer
Narrowing of airways: Asthma is caused by spasm in the small airways in the lungs the wheezing is like a whistling sound that occurs when you try to push air through an area of spasm that is too tight to allow normal flow. Think of it like when you whistle, you force air past an obstructed opening and creat turbulance that maks the sound. Whistles are not a vocal cord sound.
