Outline of Final Research Achievements

The chest compression is one of the most important actions for first-aid cardiopulmonary resuscitation. Because it requires large torque/force to be generated, the performers have to take an energy saving position and motion until advanced life support providers take over. The energy saving motion strictly depends on the body weight and height of the performers. In this research, the chest compression is optimized from kinematic and dynamic point of view. By using Pseudo-differential and zero-phase filter, the angular velocity and acceleration are derived from a motion capture data, and generative force is calculated by inverse dynamic computation. Based on an evaluation function and constraints, the chest compression is optimized kinematically, dynamically and temporally. Moreover, for the chest compression of a child with light weight, a motion aid is optimized. The effectiveness of the proposed method is evaluated based on a physical load of the performers by measuring heart rate.
