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.
Outstanding acoustics with better audibility of high-frequency sounds (adult side, firm pressure).
Tunable diaphragm: Hear high or low frequency sounds by slightly adjusting pressure on the chestpiece.
Dual-lumen tubing: Two sound paths in one tube eliminates the rubbing noise of traditional double tubes.
