3M Littmann Cardiology IV 27" Diagnostic Stethoscope 5223
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.
Next-generation tubing lasts longer and resists stains. Not made with natural rubber latex or phthalate plasticizers.
Headset is easily adjusted for individual fit and comfort. Angled eartubes align with ear canals.
9 out of 10 acoustic performance rating.
7 year warranty, made in the USA.

I'm in love with my stethoscope! I'm a veterinary nurse and rely on a good quality stethoscope when monitoring my sedated or anesthetized patients. This stethoscope allows me to to use both sides of the head with a simple twist. This comes in so handy with my smaller and/or larger patients.
My order also came in fast. I highly recommend this stethoscope!

I got the Littmann Cardiology IV as a gift for nursing school I absolutely love it! I can hear so clearly with it. I compared it to some other stethoscopes around and it sounds so much crisper and louder than any other one I tried. I will be using this for many years to come. I absolutely recommend this one! I got the Caribbean Blue with polished smoke and it looks incredible. The engraving also looks like quality work. I am very happy with this stethoscope and you will be too.

Highly recommended! I bought this as a gift for my fiancee who works in a step-down unit. He’s very excited to use it every time as it is much more sensitive to distinguish between normal and abnormal lung sounds and murmurs. Overall, happy with the purchase and the engraving was great addition to it!:)

We bought this for our nursing school daughter for Christmas. Her aunt who is also a nurse suggested the cardiology stethoscope which she loves and still owns, purchased over thirty years ago. My daughter LOVED it and can't wait to get back to school to use it. We chose the raspberry with smoke stems and rainbow bell. The engraving looks amazing. Delivered very quickly. Thank you!

Best stethoscope I have ever owned, great quality and very clear sound. Took a little longer for delivery then I expected but worth the wait

It is a great scope, have used Littmann for 8 years now. Fits in my ears better than my patient that just “fell” on An object and can’t get it out.

Bought this for my son who graduated from RN program. I chose gray which is a very nice color for a guy. Packaged nicely. The engraving is very nice and a must.

Highly recommend this stethoscope! It really is a huge upgrade from the Classic II. You can detect subtle sounds with this stethoscope that are harder to hear with a lesser one. Definitely worth the price.
