3M Littmann Cardiology III Stethoscope

  • Versatile, double-sided chestpiece for adult and pediatric auscultation.
  • Pediatric side converts to an open bell by replacing the diaphragm with a non-chill bell sleeve (included).
  • 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.
  • Headset is easily adjusted for individual fit and comfort. Angled eartubes align with ear canals.

3M Littmann Cardiology Details

The 3M Littmann Cardiology III Stethoscope, one of the most recognized stethoscopes in the profession, 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.

Tunable diaphragm technology—a 3M invention—lets clinicians hear different frequency sounds by simply adjusting the pressure on the chestpiece. Hold the chestpiece with light pressure to hear low frequency sounds; press a little more to hear higher frequency sounds. This time-saving feature allows the healthcare provider to focus on the patient, while the non-chill rim provides patient comfort.

Headset tension is easily adjusted for head size and comfort by squeezing together or pulling apart the eartubes. Snap-tight, soft-sealing eartips conform to individual ears for an excellent acoustic seal and comfortable fit. Eartips snap firmly onto the ends of the eartubes and, for safety, require a significant effort to remove.

Resilient next-generation tubing retains its shape and flexibility even after folding tightly into a pocket. It provides longer stethoscope life due to improved resistance to skin oils and alcohol, and is less likely to pick up stains. Next-generation tubing is not made with natural rubber latex, a benefit to sensitive medical professionals and their patients. And, to play its part in the protection of human health and the environment, the next-generation tubing does not contain phthalate plasticizers.

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. The Cardiology III stethoscope is made in the USA for consistent quality. It comes complete with large and small soft-sealing eartips, large firm eartips, non-chill bell sleeve, and instructions.

In just two days my purchase arrived and I could not have been more excited to open the box. As a Nursing student I kept hearing professors and upper classmen recommend both this model scope and this website. The engraving and the color is true to the site. I am absolutely in love with my new scope.

I could hear breath sounds CLEARLY, even through clothes! it was very exciting to actually be able to hear what I needed to hear, and hear it ever so clearly. This is a wonderful stethoscope, I highly recommend and will never let it out of my sight! sound quality is amazing and perfect for a bedside/floor nurse, or in my case perfect for a nursing student. Love the colors.

Light weight, ear plugs block out surrounding noise, making auscultation clear and distinct. Great product, I would recommend!
Roxy | Rating: 5" />
People have given me compliments about the bright tubing color and smoke finish. I've been using a Littmann Cardiology III for 8 years and I won't use another model. It is loud and allows me to be confident in my assessment.
