Background of the invention

Cardio Pulmonary Resuscitation (CPR) is a lifesaving technique during resuscitation from cardiac arrest. The AHA recommends performing CPR before and during AED use. However, performing CPR on a cardiac arrest victim causes artifacts on the ECG rhythms recorded by the AED device. To this end, algorithms like ART could estimate the shockability of the underlying ECG wave even under the presence of CPR artifact. These algorithms improve the chance of resuscitation without asking the rescuer to pause. Due to this change in the rescue protocol, the user interface and interactions with the AED need an overhaul.

Problems or disadvantages overcome by the invention

Current CPR manikins and simulators are a good training tool to learn how to perform CPR. However, they are sub-optimal when used in conjunction with an AED. In general, the AED receives simulated ECG rhythms from a simulator, while the trainee performs CPR and attends to the patient. While advanced simulators are capable of adding a CPR artifact to the ECG, this artifact is independent of the trainee CPR. For example, the simulator might present uncorrupted ECG rhythms to the AED even when the trainee performs CPR. When this happens during an analysis phase of the AED after a CPR interval, the current simulator and manikin systems present a CPR artifact free rhythm to the AED, even if the trainee continues to perform CPR. If the trainee applies the same methodology during a field episode, the AED would detect the CPR artifact. This is a major gap in CPR training and in the user interface of the AEDs.

This invention would bridge this gap by providing accurate CPR artifcat on both the impedance channel and the ECG channel of the AED during training. Training with such a manikin would provide a more accurate representatio...
