Abstract: A mannequin for cardiopulmonary resuscitation training, the mannequin includes: a torso case (102); a torso cover (104); a head case (106); a head cover (108); a spring (110); a first column (112); a second column (114); a pivoting arm (118); a sensor case (132); a first infrared sensor (134) and a second infrared sensor (136); and a blocking plate (140), wherein, when the blocking plate (140) moving in an up and down direction covers a front surface of the sensor case (132), the first infrared sensor (134) and the second infrared sensor (136) check a state in which infrared rays are not sensed, and then transmit the state to a control portion. Accordingly, when cardiopulmonary resuscitation is performed, it is possible to easily and accurately determine how deep the compression is, and to accurately sense whether the direction of compression is perpendicular to the ground, so trainees learning cardiopulmonary resuscitation can undergo an accurate training.
