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, 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.
What is the warranty on the Littmann Cardiology IV stethoscope with mirror chestpiece?
The Littmann Cardiology IV stethoscope carries a seven-year warranty.
Is the Littmann Cardiology IV suitable for pediatric patients?
The Littmann Cardiology IV is designed for use with both 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.
How does the tunable diaphragm work on the Littmann Cardiology IV?
The Littmann Cardiology IV uses tunable diaphragm technology that lets clinicians hear different frequency sounds by adjusting the pressure applied to the chestpiece. Light pressure captures low-frequency sounds, and incrementally increased pressure shifts auscultation to higher-frequency sounds — all without flipping or changing the chestpiece.
What low-frequency heart sounds can the Littmann Cardiology IV detect?
The Littmann Cardiology IV is designed to more reliably and consistently detect heart sounds at frequencies below 120 Hz, including Korotkoff sounds, Mitral Stenosis, and S3 and S4 Gallops. This performance is based on tests against globally available comparable stethoscopes in an equivalent class using recorded heart sounds with a diaphragm.
What are the tube and chestpiece specifications for the Littmann Cardiology IV mirror model with black tube?
The Littmann Cardiology IV with mirror chestpiece and black tube has an overall length of 27 inches (69 cm), a chestpiece weight of 3.1 ounces (87 g), a diaphragm diameter of 1.7 inches (4.3 cm), and a small diaphragm diameter of 1.3 inches (3.3 cm). The binaural construction is double lumen, and the headset is made from wide-diameter aerospace alloy and anodized aluminum.
What clinical settings is the Littmann Cardiology IV mirror chestpiece model intended for?
The Littmann Cardiology IV with mirror chestpiece is intended for critical care and challenging environments, including cardiac units and the ICU. It is also suitable for a range of healthcare professionals who need to identify and study cardiac, lung, and other body sounds in adult and pediatric patients.
How does dual-lumen tubing on the Littmann Cardiology IV reduce noise during auscultation?
The Littmann Cardiology IV uses dual-lumen tubing that combines two sound paths within a single tube, eliminating the rubbing noise produced by traditional double tubes. This design helps ensure that ambient mechanical noise does not interfere with auscultation.
What is the diaphragm material on the Littmann Cardiology IV stethoscope?
The diaphragm on the Littmann Cardiology IV stethoscope is constructed from epoxy and fiberglass. Both sides of the chestpiece feature single-piece diaphragms that are designed to be easy to remove and clean.
