To improve the way medical students and residents learn to distinguish various heart sounds, a new infrared wireless system was recently acquired by AISR and the Department of Medicine that consists of an interface/transmitter and 135 receiver/stethophones. The interface unit can accept input from any audio source, such as a cassette player or a computer, and using an infrared "antenna" transmit the sound to the receiving stethophones.
Each stethophone consists of an infrared receiver, a sound chamber and a standard stainless steel binaural with rubber tips. A patient auscultation unit has also been ordered and is expected soon.
The system is being used during the second year ICM course, but also during the medicine clerkship of the third year (students meet weekly with Dr. Mangione to review various cardiac and pulmonary sounds) and for educational programs targeting Internal Medicine and Family Medicine residents.
For information on using the stethophones, please contact Medical Media Services.
