Q

What is the difference in wheezes & crackels?

A

Wheezes:
* continuous sounds
* heard on expiration & sometimes on inspiration as air passes through airways constricted by swelling, secretions, or tumors
* classified as sibilant (high [i]) or sonorous (low [o])

Crackles:
* intermittent sounds
* occur when air moves through airways containing fluid
* classified as fine, medium, or coarse
