All 3M™ Littmann® Stethoscopes offer advanced sound performance and a comfortable fit, thanks to innovative features built into each stethoscope. Discover how each stethoscope part functions, and how they work together to help you achieve the best in your profession.
Various auscultation sounds occupy set regions in the high and low frequency ranges. As shown in the diagram above, some of these frequencies substantially overlap one another. Because of this, it is important for clinicians to isolate high and low frequencies, and detect and differentiate subtle sounds with their stethoscope.
The tunable diaphragm of a Littmann stethoscope makes auscultation more efficient by eliminating the need to remove, turn over, and reposition the chest piece to hear different frequency ranges.
By adjusting the pressure applied to the chest piece, clinicians can isolate each frequency range to discern subtle sounds.
Light pressure allows low-frequency sounds like S1 and S2 sounds to be heard, while firm pressure will restrict the movement of the diaphragm membrane, block low-frequency sounds, and allow higher-frequency sounds such as respiratory sounds to be heard.
Convenience: Spend less time positioning stethoscopes to hear all auscultation sounds.
Comparison: Isolation of low and high frequencies provide critical comparisons that offer valuable assessments.
Consistency: You don’t have to worry about placing your diaphragm in the exact spot where you’ve picked up an anomaly. Simply apply pressure.
3M™ Littmann® Stethoscope chest pieces are precision-machined to capture sounds effectively while having an aesthetically pleasing shape. They are either one-sided with a tunable diaphragm or two-sided with a diaphragm on one side and a bell on the other.
Chest pieces on the 3M™ Littmann® Classic III™ and 3M™ Littmann® Cardiology IV™ stethoscopes are double-sided with tunable diaphragms on the adult and pediatric sides, which means you only need one stethoscope to auscultate all ages and sizes of patients.
It only takes 56 seconds to make a meaningful human connection with a patient – so why not use your stethoscope as a tool to impart a personal touch?
