Ideal for lung sound classification training with real lung sounds recorded from actual patients. 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.
