Document Summary
Auscultation is what a physician does when they listen to your chest. If you connect those lines you get 4 points. You can project those points onto the anterior chest wall. Ur corner, ul corner, and lr corner are at the sternum; however, lower left corner: is at the 5th intercostal space at the mid clavicular line. If you draw a perfectly perpendicular line from the middle of the clavicle, that"s where the line is. Showing where a physician will put his stethoscope. We can isolate the sounds of the 4 valves, and can determine whether a valve is defective based. E. g. if you hear swishing after valve contracts, that means something is leaking. Pulmonary, aortic, mitral, tricuspid valve (mnemonic: pray at midterm) You can correlate the heart sounds to what"s going on in the heart physiologically and. If you listen to a heartbeat, you hear lub dub which are caused by closing of the valves.
