Cascade HealthCare Products carries the 3M™ Littmann® Master Cardiology™ Stethoscope, featuring tunable diaphragm technology that lets clinicians hear different frequency sounds by simply adjusting the pressure on the chest piece. Unlike two-sided models, there is no need to turn over and reposition the chest piece. Hold the chest piece 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.
