A Novel Method of Measuring the Depth of Manual Chest Compressions During CPR

The present study offered a novel method to determine the depth of manual chest compressions during Cardiopulmonary Resuscitation (CPR). This method was based on the accelerometer and the gyroscopes. In our study, several algorithms of measuring the depth of compressions with one accelerometer and two gyroscopes were established. We also built an experimental platform to monitor the movement of rescuer's hand. In order to validate our method, a series of tests based on our experimental platform were carried out. Results showed that this method of measuring the depth of chest compressions was feasible and simple, and that the data acquired by our method were reliable and accurate. This novel method will provide assistance and a real-time monitor for the rescuers during CPR.
