Stethoscopes allow physicians to listen to the heartbeats and breathing of their patients to check for any abnormalities. The disk-shaped resonator is placed on the chest of the patient and can detect a range of sounds and frequencies, which are then transmitted to the ears of the physician through the rubber tubing. Stethoscopes are available for both adults and children in a wide variety of colors. QuadMed offers a large selection of Stethoscopes from top brands like 3M™ Littmann, ADC, GRx Medical, or Prestige Medical.
