Abstract: The present disclosure relates to a mannequin for cardiopulmonary resuscitation training. More specifically, the present disclosure relates to a mannequin for cardiopulmonary resuscitation training in which a magnet is installed at a distal end of a pivoting arm that pivots up and down inside a mannequin body, two sensors are installed at different heights of two columns such that the position of the pivoting arm is detected, and a behavior of cardiopulmonary resuscitation as performed by trainee is analyzed, and, thus, whether the trainee is performing cardiopulmonary resuscitation in accordance with the regulations is figured out. According to the present disclosure, when cardiopulmonary resuscitation is performed, it is possible for the user to easily and accurately determine how deeply the user is pressing the device. As a result, trainees who learn cardiopulmonary resuscitation can do accurate training.
