Lung Sound Auscultation Trainer "Pediatric LSAT"

Product supervision:
Yuki Okamatsu, Director of Pediatrics, Iizuka Hospital, Japan


This unique trainer can offer more efficient and effective respiratory auscultation training.
The physical status adjustable by touching control PC. Students specializing in pediatrics can learn the basics of pediatric respiratory auscultation.



Respiratory rate

Pediatric LSAT simulates the respiratory system 1 to 5 years olds allowing for an adjustable rate of 15 to 50 breaths per minute.

Heart rate

Pediatric LSAT automatically sets the heart rate to the respiratory rate(le: 90 beats/minute per the respiratory rate of 20 breaths per minute. 140 beats/minute per the respiratory rate of 40 breaths/minute. etc)

Differentiation of sound

Reproduces accurate pediatric lung sound. Unlike an adult subject, Pediatric LSAT is designed so sounds are easily recognizable as being either from the upper and lower lung fields.

Model shape

Pediatric LSAT is designed to accurately reflect the chest size of a subject from 1 to 5 years of age.



Wireless multi-unit operation

Up to five “Pediatric LSAT” can be controlled by one wireless control PC.

Each simulator can be individually programmed.

Cases can be switched at any time with a simple touch.


Simultaneous anterior and posterior auscultation

Two or more trainees can work together at the same by real stethoscopes.

Create a custom playlist

With 20 different cases.
Incorporated "Playlist Maker" facilitates creating and conducting scenario based training sessions which feature change in finding over time.

Playlist Maker facilitates:
- sessions with accompany temporal change in physical findings
- standardizing training contents among different instructors.
- saving time of preparation


Error Indication System

The error indicator performs check-up of the system to keep Pediatric LSAT in its best condition. Troubles and errors in speakers are warned on screen. History of system conditions is automatically recorded for reference.

Classification of Lung Sounds

Based on acoustic analysis of recorded lungs sounds, each are classified according the American Thoracic Society standards. With this approach, lung sounds are categorized as continuous (wheezes, rhonchi, or stridor) or discontinuous (crackles). Crackles are further identified as fine or coarse.





weak: left lower area / weak: left whole area / weak: right lower area / weak: right whole area

Coarse crackles

right lower area / both lower area / left lower area / both upper area / whole area / right upper area

Fine crackles

both lower area / whole area


trachea and upper area / whole area
