Abstract: A manikin and control system is provided for use by a student practicing a procedure usually applied to the human body, such as cardiopulmonary resuscitation. The system includes a manikin that has an artificial lung into which the student can blow to expand the lung, and a resilient chest which the student can compress. Sensors are provided in the manikin to accurately detect the instantaneous amount of lung expansion and chest compression. An A/D converter converts the sensor signals to digital signals and inputs them to a compact controller based on an inexpensive microcomputer chip which also stores the control program in ROM. Pushbuttons on the controller's front panel enable the student to select any one of a variety of teaching routines prestored in the microcomputer's ROM. The microcomputer then uses lamps on the panel and a speech synthesizer having prerecorded human speech stored in external ROM chips to issue instructions and advice to the student.
