Examples
The following examples show the effects of See-Thru CPR filtering on ECG signals
contaminated with CPR artifact.
Each example includes:
•
ECG signal with CPR artifact.
•
ECG signal after the See-Thru-CPR filter has removed CPR artifact.
•
Indication of the period during which See-Thru CPR is active.
•
CPR signal to show when CPR activity occurred.
Figure 1 shows a patient in Fine VF. It is difficult for a rescuer to discern this rhythm during
CPR compressions. When the CPR filter turns on, the Fine VF rhythm becomes more obvious.
