3M Littmann Cardiology IV Diagnostic Stethoscope

The 3M Littmann Cardiology IV Diagnostic Stethoscope is a premium clinical instrument designed for healthcare professionals who need enhanced acoustic performance during detailed patient assessment. It is particularly suited to physicians, nurses, cardiology professionals, and clinicians working in environments such as intensive care, emergency departments, and general clinical practice.

Its dual-sided chestpiece features two tunable diaphragms, allowing clinicians to hear a broad range of frequencies by adjusting the pressure applied to the chestpiece. The larger adult side is designed for general examination, while the smaller side can be used for pediatric or more focused assessments.

The chestpiece is precision-machined from stainless steel for durability and reliable acoustic performance. A dual-lumen tubing system combines two sound paths within a single outer tube, helping provide a clean, streamlined design. The tubing is designed to resist skin oils and alcohol and does not contain natural rubber latex.

Soft-sealing eartips provide a comfortable acoustic seal, while the adjustable headset allows the user to position the eartips securely. The Cardiology IV is designed for demanding clinical environments where clear auscultation is important for cardiovascular, pulmonary, and other physical assessments.
