1. A computer-implemented method for providing summary information for lifesaving activities, the method comprisingsensing one or more activities that are repeatedly and cyclically performed on a victim by a rescuer;

  • identifying a cyclical timing interval over which performance is to be analyzed for a integer number of cycles of the one or more activities, and gathering data from the sensing of the one or more activities during the time interval;

    generating, from analysis of the one or more activities, summary data that condenses data sensed for the one or more activities into a summary of the one or more activities, wherein the summary data identifies both rate and amplitude information that reflect a rate and amplitude at which the rescuer performed at least one of the activities; and

    providing, for display to a user, a visual summary of the performance of the one or more activities over the identified time interval, the visual summary of the performance indicating a quality of performance of the at least one of the activities based on a combination of the rate and amplitude information that reflect a rate and amplitude at which the rescuer performed at least one of the activities.
