Engineered for Critical Care Excellence

The Cardiology IV is specifically designed for healthcare professionals who work in critical care and challenging environments including the ED, ICU, Cardiac ICU, step-down units, and other dynamic locations. This stethoscope helps you detect hard-to-hear sounds such as aortic stenosis, S3 gallop murmurs, and faint pulmonary anomalies, sounds that are critical for accurate diagnosis and treatment decisions.

With better audibility of high-frequency sounds compared to the Cardiology III (adult side, firm pressure), you can hear subtle changes in patient status and diagnose with confidence. The tunable diaphragm technology allows you to assess both low and high-frequency sounds by simply adjusting pressure, keeping your focus on the patient during critical moments.

High-Profile Ergonomic Design

The ergonomic, high-profile construction features a significantly larger acoustic chamber, 40% larger chestpiece and 60% deeper bell than the Classic III, allowing for superior sound capture and isolation. The dual-sided stainless steel chestpiece with tunable diaphragm and open/closed bell provides maximum diagnostic versatility across adult and pediatric patients.

Revolutionary Satin Finish Tubing: Comfort Meets Performance

Experience the difference of Satin Finish Tubing in professional black, specially formulated to enhance your critical care workflow. This advanced coating provides a softer, silkier feel that won't stick to hair or clothing during urgent examinations. The flexible construction allows for effortless folding and stowing in lab coat pockets.

The satin coating delivers practical benefits throughout demanding shifts: superior stain resistance, easy-to-clean surface for infection control, and scratch-resistant properties. The double-lumen tubing design eliminates interference from rubbing sounds, ensuring the clearest possible acoustic transmission while resisting skin oils and alcohol.

Built for Extended Critical Care Shifts

Soft-sealing eartips conform to individual ear anatomy, creating an excellent acoustic seal that blocks ambient noise in busy critical care units. The headset tension adjusts easily for personalized comfort during long shifts. The non-chill bell sleeve provides patient comfort during examinations, even in urgent situations.
