Lung Sound Auscultation Trainer

Made in Japan

Outstanding sound quality
  • Cases are recorded from actual patients; sounds are exactly those of real patients.
  • Computer synchronization of all outputs.
  • Sounds can be monitored graphically in real time.
  • The sound volume, the pace of respiration and the operating time are adjustable, expanding the variety of training options.
  • Actual stethoscopes can be used for training.
  • External speaker system facilitates demonstrations and group study.
Accurate location and spread of lung sounds
  • 15 speakers are located in the torso manikin (seven in the anterior, eight in the posterior), each speaker playing back sounds distinct to each auscultation area. Speakers are completely synchronized.
  • The torso rotates on a base, allowing examination of both the front and back as in a real clinical procedure.
  • Actual stethoscopes can be used for training.
Efficient selection of the cases
  • 35 lung sound cases and one example of vocalfremitus are available with the system.
  • Each case has 2 variations, with and without heart sounds. (exceptions: normal with loud heart sounds, Hamman's sign)
  • Cases are carefully selected for educational purposes based on classification standards of the American Thoracic Society.
Useful explanation windows 
  • Explanation window for each case can be referred on the monitor.
  • General descriptions along with clinical data on individual cases including patient histories, illustrations, radiographs and CT images.

Lung Sound Auscultation Trainer

LSAT is a single-purpose simulator for lung sound auscultation training. Lung sound auscultation is one of the essential steps in chest examination. This skill requires three areas of expertise listening to the sounds of a patient's chest with proper use of the stethoscope, having a clear understanding of sound variations and being able to describe these sounds clearly to others. In addition, in order to give a diagnosis, relations between sounds and auscultation sites play an important role. Trainees learn not only to distinguish the sounds and their location, but to comprehensively understand what they indicate.
