Also known as phonendoscope, stethoscopes

The stethoscope (from Ancient Greek () and () ) is a medical device for auscultation, or listening to internal sounds of an animal or human body. It typically has a small disc-shaped resonator that is placed against the naked skin, with either one or two tubes connected to two earpieces. A stethoscope can be used to listen to the sounds made by the heart, lungs or intestines, as well as blood flow in arteries and veins. In combination with a manual sphygmomanometer, it is commonly used when measuring blood pressure. It was invented in 1816 by René Laennec and the binaural version by Arthur Lea

AI overview

A stethoscope is a medical instrument that allows doctors to listen to internal sounds in the body, such as heartbeats, breathing, and blood flow, by placing a small disc against the skin and using earpieces to hear the sounds. It has been an essential diagnostic tool since its invention in 1816 and remains widely used today, particularly when checking heart and lung health or measuring blood pressure.

A stethoscope that intensifies auscultatory sounds is called a phonendoscope.
