Patent attributes
An exemplary method of identifying a source of chest compressions administered during cardiopulmonary resuscitation (CPR) includes receiving, at a processor, signals indicative of pressure exerted during the chest compressions from at least one sensor communicatively coupled to the processor and disposed at a location on the victim's chest away from an indicated compression point for manual chest compressions, generating a compression waveform based on the received signals, detecting compression waveform features representative of the chest compressions based on the compression waveform, comparing the detected compression waveform features to a pre-determined criterion to discriminate between chest compressions from an automated compression device and manual chest compressions, determining whether the chest compressions are from the automated compression device or the manual chest compressions based on the comparison, and generating an output based on whether the chest compressions are determined to be from the automated compression device or the manual chest compressions.
