Stethoscope Auscultation?

Question

Does anyone know any good sites with auscultation sound, programs, samples....im using the littmann stethoscope, and does anyone know where to get their cds with sounds?thanks

We have patients with mitral stenosis, murmors...but some things you can't hear, either it's rare or patients come and go before we get to them, so id love some reference, just to know what to pay attention to if i do come across it one day

Auscultation is the technical term for listening to the internal sounds of the body, usually using a stethoscope. Auscultation is normally performed for the purposes of examining the cardiovascular system and respiratory systems (heart and lung sounds), as well as the gastrointestinal system (bowel sounds).

Auscultation is a skill that requires substantial clinical experience, and good listening skills. Heart sounds are rather faint, especially when an acoustic stethoscope is used. Recently, electronic stethoscopes by Thinklabs, Welch Allyn, 3M and others have become available, making heart and lung sounds more clearly audible to the clinician. The electronic stethoscope also allows for recording of sounds and transmission for the purposes of telemedicine, or remote diagnosis. Thinklabs uses a novel electronic diaphragm detection system to directly convert sounds into electronic signals. Welch-Allyn uses a piezo-electric sensor on a metal shaft inside the chestpiece, while 3M uses a conventional microphone. These advances are likely to ensure that auscultation remains a primary screening tool for clinicians, as a precursor to more costly tests such as ultrasound.

Doctors listen to 3 main organs during auscultation: the heart, lungs, and the gastrointestinal system. When auscultating the heart, doctors listen for abnormal sounds including heart murmurs, gallops, and other extra sounds coinciding with heartbeats. Heart rate is also noted. When listening to lungs, sounds such as wheezes, and crackles. The gastrointestinal system is auscultated to note the presence of bowel sounds

Learning the accurate and reliable interpretation of auscultation findings has been improved by recent technological advances. There is a web site, the http://www.med.ucla.edu/wilkes/intro.html which "provides heart sounds, heart murmurs, and breath sounds in order to help medical students and others improve their physical diagnosis skills

hope this helps

Heart sounds are the real bugger trying to recognize gallup rhythms and other sounds or valves at opening and closing.
