Cascade HealthCare Products carries the 3M™ Littmann™ Cardiology III Stethoscope, which combines outstanding acoustics and superior versatility. This instrument is one of the most recognized stethoscopes in the profession, featuring 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 chest piece converts to a traditional open bell by removing the tunable diaphragm and replacing it with the included non-chill bell sleeve.

The Cardiology III stethoscope isn’t just for cardiologists. It is used by specialist 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.
