last for many years and provide excellent service while doing so.
Littmann is the most highly recognized, most often purchased and
preferred stethoscope in the Medical field. These stethoscopes
have demonstrated a working lifespan of over 30 years, with

Which Stethoscope to Choose ?





Cardiology: Superior acoustics. Classic models have single channel
in tubing. Cardiology models have dual channels in tubing, one to each
ear for “stereo” sound. Scale of 1 -10, Master Cardiology rated 10, Cardiology III
rated 9. Only slightly better acoustics with Master model, with smaller “deadspace”
in the chestpiece.
 Which Cardiology Model? Cardiology III. Master Cardiology has single
 sided chestpiece only allowing use of Tunable Diaphragm as explained on Slide #
7.
 1) Is most widely used by physicians and most widely chosen by students.
 2) Cardiology III has both bell and diaphragm sides for versatility.
 3) Easier to learn High and Low frequencies as requested by professors.
 4) Bell side can be converted for Pediatric assessments by utilizing the

tunable diaphragm.
 5) More versatile and economical.
