Auscultation is a medical term for listening to the sounds the internal organs of the body makes. This procedure has proven invaluable both as a diagnostic and monitoring tool since a person’s internal organs produce an extremely limited range of sounds that can be considered normal. By listening for any deviation from this range, a medical professional can tell if a person is suffering from an illness. One can simply listen to the patient’s heart or breathing using one’s ear, but this method is inefficient especially if the environment is noisy. The most efficient method for performing auscultation is to use a stethoscope. This medical device lets you listen to internal sounds more clearly allowing you to properly monitor a patient.
