Abstract:
A device for estimating an actual ECG signal of a patient while performing chest compressions, said device comprising:a means for performing chest compressions on a patient; a means for sensing the ECG signal of the patient, said means for sensing the ECG signal capable of producing a measured ECG signal corresponding to the measured value of the ECG signal of the patient, wherein the ECG signal comprises an actual component and a noise component; a compression sensor operably connected to the means for performing chest compressions, said compression sensor capable of producing a compression signal corresponding to the presence of a chest compression; a processor operably connected to the compression sensor and to the means for sensing the ECG signal, said processor capable of producing an estimated actual ECG signal corresponding to the estimated actual ECG signal of the patient; wherein the processor further comprises: a system identifier operably connected to the compression sensor, said system identifier capable of producing the estimated noise component of the ECG signal; wherein the system identifier produces the estimated noise component of the ECG signal by processing the measured ECG signal and the compression signal; and a means for combining signals operably connected to the system identifier and to the means for sensing the ECG signal, said means for combining signals capable of combining the measured ECG signal and the estimated noise component of the ECG signal to produce the estimated actual ECG signal.
