    • Title : Cardio Pulmonary Resuscitation Feedback System 5 A CPR feedback system (20) for assessing CPR carried out by a person on a subject and providing CPR feedback to the person, comprising an ECG system (22) configured to measure ECG signals of the subject, a biosignal system (24) configured to measure biosignals of the subject, a CPR assessment system (26) connected to the ECG system to receive ECG signals and connected to the biosignal system to receive biosignals, and a 10 CPR feedback unit (28) connected to the CPR assessment system and configured to receive CPR feedback signals and issue CPR feedback to the person, wherein the CPR assessment system is configured to perform the steps (i) establish a reference ECG signal metric and a target biosignal metric, (ii) produce a CPR feedback signal advising the person to start CPR, (iii) receive ECG signals measured during a plurality of chest 15 compressions and use the ECG signals to establish a current ECG signal metric, (iv) receive biosignals measured during the plurality of chest compressions and use the biosignals to establish a current biosignal metric, (v) compare the current ECG signal metric with the reference ECG signal metric and compare the current biosignal metric with the target biosignal metric, (vi) when the current ECG signal metric is less than the reference ECG 20 signal metric and the current biosignal metric is less than the target biosignal metric, produce a CPR feedback signal advising the person to improve CPR performance, (vii) when the current ECG signal metric is less than the reference ECG signal metric and the current biosignal metric is equal to or greater than the target biosignal metric, increase the target biosignal metric and produce a CPR feedback signal advising the person to 25 improve CPR performance, (viii) when the current ECG signal metric is equal to or greater than the reference ECG signal metric, set the reference ECG signal metric equal to the current ECG signal metric and produce a CPR feedback signal advising the person to maintain current CPR performance. 30 Figure 1 CPR FEEDBACK SYSTEM 20 22 BIOSIGNAL SYSTEM CPR ASSESSMENT CPRFEEDBACK Fig. 1
