System and Method for Distinguishing Manual from Automated CPR

摘要

A system and method for use during the administration of CPR chest compressions and defibrillating shock on a cardiac arrest victim. The system analyzes compression waveforms from a compression depth monitor to determine the source of chest compressions, and enables the delivery of defibrillating shock during a compression cycle if the compression waveforms are characteristic of an automated CPR chest compression device.

1. A method of controlling a defibrillator to resuscitate a cardiac arrest victim in which said victim may be treated with CPR chest compressions which cause motion of the patient's chest, wherein the defibrillator is operable to administer electrotherapy to the cardiac arrest victim according to shock advisory algorithms, said method comprising the steps of:
acquiring motion signals from a motion sensor operable to generate motion signals corresponding to motion of the chest of the cardiac arrest victim and generating a compression waveform corresponding to motion of the chest of the cardiac arrest victim; operating a control system operable to control the defibrillator to analyze the compression waveform to determine whether chest compressions are performed manually or by an automated chest compression device, and operating the control system to control delivery of electrotherapy based on the determined source of chest compressions.
