I need help with differentiating different Heart sounds and the same goes for lungs sounds ( wheeze, ronchi, crepitations), Abdominal sounds( hyperactive/hypoactive bowel).

There are sites like Umichigan and I've googled for results, but I thought I might ask here so someone could tell me if a comprehensive source for PE and how to differentiate the various sounds exists. Thanks

Here are some random tips:

Bowel sounds are fairly useless
Get really good at telling when breath sounds are decreased in certain fields
Get really good at telling when you have prolonged or shortened I:E ratios

Bowel sounds are "present" or "absent" and "absent" means you stood there and listened for 5 minutes in each quadrant and heard nothing, which means straight to surgery.

For lung sounds, just listen to lots of lungs. This isn't something you need to sit down at a computer to learn ahead of time. Listen to wheezes on your peds rotation when you have a good asthmatic. Listen to crackles and decreased breath sounds in your elderly patients on your inpatient medicine rotation. Lung sounds are pretty obvious once you hear them. They sound exactly like described. It's not the mental gymnastics of a crescendo-decrescendo holosystolic machine-like murmur in the 4th intercostal space radiating to the pelvis or whatever those heart people come up with.

And it's helpful to think about whether you hear the wheeze during inspiration, expiration, or both.
