Auscultation is a medical technique used to listen to the internal sounds of the body, primarily the heart and lungs. Healthcare professionals use a device called a stethoscope to amplify these sounds, allowing them to assess the condition of organs and detect any abnormalities. This method is essential for diagnosing various health issues, such as heart murmurs, lung infections, and other respiratory conditions. By analyzing the sounds produced during breathing or heartbeats, doctors can gather important information about a patient's overall health and make informed decisions regarding treatment.
