1. A system comprising:
- an energy output module comprising an electrical circuit configured to generate a defibrillation shock;
a plurality of sensors comprising sensors configured to generate signals indicative of chest compressions and ventilation;
a memory and one or more processors configured to;
receive the signals indicative of chest compressions and ventilations,process the signals indicative of chest compressions and ventilations to determine chest compression parameters and ventilation parameters, anddetermine rescuer feedback based on the chest compression parameters and ventilation parameters and based on a control algorithm, stored in the memory, and configured to determine an indication of an estimated physiological impact of at least a rate associated with delivery of at least one of chest compressions and ventilation to a patient by a rescuer, andone or more output devices communicatively coupled to the one or more processors and configured to provide the rescuer feedback for the rescuer during the delivery of at least one of chest compressions and ventilation by the rescuer,wherein the provided rescuer feedback comprises;
one or more of an audible cue and a visible cue, wherein a variation in the one or more of the audible cue and the visible cue provides chest release information,graphical feedback indicative of a quality of at least one of blood flow and ventilation, the graphical feedback comprising the indication of the estimated physiological impact of at least the rate associated with the delivery of at least one of chest compressions and ventilation,feedback indicative of the chest compression parameters and comprising a graphically displayed target zone for at least one of the chest compression parameters and a graphically displayed comparison between the at least one of the chest compression parameters and the target zone,feedback indicative of the ventilation parameters, andfeedback based on a waveform corresponding to the chest compression parameters.

Abstract
A medical device of the type used for assisting a user in manually delivering repetitive therapy to a patient (e.g., chest compressions or ventilations in cardiac resuscitation), the device comprising a feedback device configured to generate feedback cues to assist the user in timing the delivery of the repetitive therapy, at least one sensor or circuit element configured to detect actual delivery times, at which the user actually delivers the repetitive therapy, and a processor, memory, and associated circuitry configured to compare the actual delivery times to information representative of desired delivery times to determine cue times at which the feedback cues are generated by the feedback device.
