Fine vs coarse crackles lung / breath audio sounds #shorts
As a nursing student and nurse, you'll want to know the different lung sounds. One area of confusion for many students is the difference between coarse crackles and fine crackles.
For coarse crackles, remember the 3 "L's": low pitch, long duration, and loud. These sounds often remind me of someone blowing a straw in water, and you can hear them during inspiration and sometimes expiration.
For fine crackles, they have a higher pitch, shorter duration, and softer sound. They remind me of the sound of crackling during a fire. You'll often hear these sounds toward the end of inspiration.
