CPR performance reporting system

Abstract

A method for assessing CPR performed during at least one resuscitation event includes obtaining a data set during each of the at least one resuscitation events, each data set including data characterizing the performance of chest compressions or ventilations, or both, on the patient during the at least one resuscitation event; processing the data set to determine a value of at least one parameter of the performance; and displaying a graphical representation of the at least one parameter. A graphical representation of a desired value or range of values of the at least one parameter may be displayed in a position for visual comparison with the determined value. A method for presenting information on a sequence of events during a resuscitation event includes: obtaining data on the sequence and timing of chest compression and lung ventilations from a defibrillator; and displaying symbols for chest compressions and lung ventilations in a linear sequence corresponding to the order in which the compressions and ventilations occurred, the linear distance between successive symbols being proportional to the temporal distance between the corresponding actions.
