Abstract: A portable medical device for adjusting a cardiopulmonary resuscitation (CPR) treatment includes a processor. The processor is configured to determine a particular CPR treatment protocol from one or more CPR treatment protocols. The particular CPR treatment protocol may include a ratio of a number of chest compressions to ventilations for administering during a CPR cycle. The processor is configured to receive a CPR time period for the CPR treatment for the CPR treatment, to determine a number of CPR cycles for the CPR treatment based on the particular CPR treatment protocol, and to calculate a time duration of the CPR treatment based on the number of CPR cycles of the particular CPR treatment protocol. The processor is configured to compare the time duration to the CPR time period and to modify the particular CPR treatment protocol or CPR time period based on the comparison.

Abstract: A method of providing assistance to a rescuer to perform cardiopulmonary resuscitation (CPR) is disclosed. The method includes receiving sensor data from one or more sensors regarding CPR compressions. The method also includes determining, on a real-time basis, a CPR parameter value for each CPR compression. The method also includes determining a summarized CPR parameter value based on each CPR parameter value. The method also includes determining whether summarized CPR parameter value satisfies a CPR threshold value. In response to determining whether the summarized CPR parameter value satisfies the CPR threshold value, the method includes causing a user interface to provide feedback information for assisting the rescuer to perform CPR on a patient.

Abstract: The system and method provide for electrocardiogram analysis and optimization of patient-customized cardiopulmonary resuscitation and therapy delivery. An external medical device includes a housing and a processor within the housing. The processor can be configured to receive an input signal for a patient receiving chest compressions and to select at least one filter mechanism and to apply the filter mechanism to the signal to at least substantially remove chest compression artifacts from the signal. A real time dynamic analysis of a cardiac rhythm is applied to adjust and integrate CPR prompting of a medical device. Real-time cardiac rhythm quality is facilitated using a rhythm assessment meter.

Abstract: Methods and apparatus are provided for determining a defibrillation treatment protocol in an external defibrillator using a measurement of elapsed time. The present invention provides a defibrillator with a timer function. Upon activation of the defibrillator, an internal timer begins to run. By closely associating the activation of the defibrillator with the onset of the patient's attack, and by making allowances for inherent time differences between these events, the timer provides a measure of the elapsed time between the onset of the patient's emergency and the presentation of the defibrillator at the patient's side. Using this measure of elapsed time, the defibrillator determines an appropriate treatment therapy, such as CPR or defibrillation therapy.
