The 3M Littmann Cardiology IV Stethoscope is the next generation of one of the most recognized stethoscopes in the profession, offering improved acoustic performance with better audibility of high-frequency sounds (adult side, firm pressure). Its distinctive chalice-shaped chestpiece features tunable diaphragms on both sides to deliver outstanding acoustic performance, diagnostic versatility, and convenience for treating adult and pediatric patients. The pediatric side of the chestpiece converts to a traditional open bell by removing the tunable diaphragm and replacing it with the included non-chill bell sleeve. The Cardiology IV stethoscope isn’t just for cardiologists. It is used by specialists and general practice physicians, critical care nurses, EMTs, medical students, and other healthcare professionals to identify, listen to, and study cardiac, lung, and other body sounds in adult and pediatric patients. It comes complete with large and small soft-sealing eartips, large firm eartips, non-chill bell sleeve, and instructions. 3M Littmann Stethoscopes are used by millions of medical professionals around the world who are dedicated to achieving the best patient outcomes. Littmann stethoscopes offer superb acoustic performance, consistently high quality, and outstanding value. Wearing a Littmann stethoscope is an expression of your commitment to medicine, and personal success.
