Integrated resuscitation
First Claim
1. A method for automatically delivering defibrillation shocks to a patient, comprising applying electrodes to the chest of the patient for delivering a defibrillation shock to the patient and for detecting an ECG signal;
- using a sensor to detect when a rescuer is delivering a CPR chest compression to the patient;
analyzing the ECG signal to determine if the cardiac rhythm is shockable (treatable by defibrillation therapy);
analyzing the output of the sensor to determine when a CPR chest compression has been delivered, and integrating the ECG analysis and CPR detection so that the determination of whether the cardiac rhythm is shockable is based on time periods of the ECG signal during which there has not been a CPR chest compression delivered.

Abstract
A resuscitation system that includes at least two defibrillation electrodes configured to be applied to the exterior of the chest of a patient for delivering a defibrillation shock, a source of one or more ECG signals from the patient, a defibrillation circuit for delivering a defibrillation shock to the defibrillation electrodes, a control box that receives and processes the ECG signals to determine whether a defibrillation shock should be delivered or whether CPR should be performed, and that issues instructions to the user either to deliver a defibrillation shock or to perform CPR, wherein the determination of whether CPR should be performed and the instructions to perform CPR can occur at substantially any point during a rescue. The control box may include a user operable control for initiating delivery of a defibrillation shock, and the instructions to deliver a defibrillation shock include instructions to activate the user operable control. The user operable control may be a button configured to be pushed by the user. The determination of whether CPR should be performed and the instructions to perform CPR may occur before a determination to deliver any defibrillation shock. The source of the ECG signals may be the defibrillation electrodes. The defibrillation circuit may be contained in the control box.
