A Feasibility Study for Measuring Accurate Chest Compression Depth and Rate on Soft Surfaces Using Two Accelerometers and Spectral Analysis

<div>Experimental setup (II). The manikin was loaded with weights (see right side of the figure) and placed on a mattress, with or without a backboard beneath its back (represented by a dark gray rectangle). One triaxial accelerometer was placed on the chest of the manikin and the other beneath its back.</div>
