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.

Features

Outstanding sound quality

Cases are recorded from actual patients; sounds are exactly those of real patients. Computer synchronization of all outputs.

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.

Efficient selection of the cases

Cases are carefully selected for educational purposes based on classification standards of the American Thoracic Society.

Useful explanation windows-including illustrations, chest radiographs and CT images-enhance training

Anterior area

  • 1 trachea
  • 2 upper right lung field
  • 3 upper left lung field
  • 4 middle right lung field
  • 5 middle left lung field
  • 6 lower right lung field
  • 7 lower left lung field

Posterior area

  • 0 upper left lung field
  • 1 upper right lung field
  • 2 middle right lung field
  • 3 middle left lung field

Actual stethoscopes can be used for training.
* Stethoscopes are not included in the unit.
