Accelerometer-Based Pushing Location Feedback Mechanism for CPR Training

Using CPR training equipment with complete feedback mechanism is a key to help people learn how to deliver high quality CPR in the emergent occasions and hence the survival rate of people who suffered from cardiac arrest can be improved. However, on some advanced CPR training models, Resusci Anne, only pushing depth and frequency feedback information are provided, but no Resusci Anne is equipped with pushing location information feedback system. In this study, an accelerometer-based sensing mechanism on Resusci Anne has been proposed to provide the feedback information about the offset distances and directions from correct pushing location. With an accelerometer mounted on the center of correct pushing location, according to the inclination and rotation angles converted from the measured data of accelerometer, the offset distances, and directions of actual pushing locations on Resusci Anne can be derived. From the preliminary test, the system can successfully provide the pushing location information during CPR training and hence help people learn high quality CPR.
