Claim One:
1. A cardio-pulmonary resuscitation (CPR) training system, comprising: a chest compression sensor configured to detect at least one parameter corresponding to chest compressions of a mannequin and generate a chest compression signal; and an electrocardiogram signal simulator comprising a transfer function with a single input to the transfer function, the electrocardiogram signal simulator configured to: receive the chest compression signal from the chest compression sensor as the single input to the transfer function; generate a first electrocardiogram signal representative of cardiac-induced electrical activity; and generate a modification signal that acts upon the first electrocardiogram signal to create a second, modified electrocardiogram signal that simulates an electrocardiogram signal of a patient undergoing chest compressions during cardiac arrest, the modification signal simulating a compression-induced artifact that would be present in a measured electrocardiogram signal in a non-simulated environment as a result of mechanical disturbances from the chest compressions, wherein the modification signal is based on the chest compression signal and is generated at least in part by applying the transfer function to the chest compression signal.
