Patent ID: 8096962

Claim:
A device for compressing a chest of a patient, said device comprising: an automated device for performing chest compressions on a patient; a means for performing defibrillation operably connected to the automated device for performing chest compressions; 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 automated device 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 and capable of performing defibrillation shocks to the patient using the means for defibrillation without stopping chest compressions being performed by the automated device for performing chest compressions; wherein the compression sensor comprises a load sensor disposed beneath the patient which senses a load when compressions begin.
