Abstract: An example of a CPR data recording system includes a hand-held chest compression measurement device and an external computing device communicatively coupled to the hand-held chest compression measurement device. The hand-held chest compression measurement device includes a housing, a motion sensor, a communication device, a memory disposed within the housing, and a processor disposed within the housing. The processor is configured to process a signal output from the motion sensor, calculate chest compression data from the processed signal output, evaluate the chest compression data after a delay from a start of the chest compressions to identify chest compressions that satisfy a pre-determined quality criterion, record the chest compression data in the memory, and send the recorded chest compression data to the external computing device via the communication device. The external computing device is configured to enable a review of the chest compression data.

Abstract: An apparatus for analyzing a patient's cardiac activity to detect cardiac events includes a plurality of ECG electrodes configured to be attached to the patient. The plurality of ECG electrodes are configured to generate two or more ECG leads. The apparatus also includes a processor in communication with the plurality of ECG electrodes. The processor is configured to generate a control vectorcardiogram loop trajectory, receive an ECG signal, generate, based on the ECG signal, a plurality of ECG vectors, and generate, from the plurality of ECG vectors, a test vectorcardiogram loop trajectory. The processor is also configured to determine at least one T wave measure by comparing the test vectorcardiogram loop trajectory to the control vectorcardiogram loop trajectory, identify, based at least partially on the at least one T wave measure, a trajectory bifurcation, and determine, based on the trajectory bifurcation, an indicator of a cardiac event.

Abstract: An example of a system for assisting a rescuer in providing CPR includes a motion sensor configured to generate signals indicative of chest motion during CPR chest compressions, and a defibrillator including a display screen configured to provide CPR feedback and defibrillation information and a processor configured to receive the signals, generate a compression waveform based on the signals, detect, in the compression waveform, features characteristic of chest compressions, compare the detected features to a predetermined criterion that distinguishes between manually delivered and compressions delivered by an automated compression device, and selectively provide the CPR feedback based on whether the compressions are the manually delivered or the automated compressions, where the selective provision of the CPR feedback includes displaying CPR parameters for the manually delivered compressions, and a removing from the display screen at least one CPR parameter of the CPR parameters for the automated compressions.

Abstract: A patient-worn arrhythmia monitoring and treatment device includes a pair of therapy electrodes and at least one pair of sensing electrodes disposed proximate to the skin and configured to continually sense at least one ECG signal of the patient over an extended period of time. The device includes a therapy delivery circuit coupled to the pair of therapy electrodes and configured to deliver one or more therapeutic pulses. A controller coupled to therapy delivery circuit is configured to analyze the at least one ECG signal and detect one or more treatable arrhythmias and cause the therapy delivery circuit to deliver the one or more therapeutic pulses to the patient. At least one of the one or more therapeutic pulses is formed as a biphasic waveform delivering within 15 percent of 360 J of energy to a patient body having a transthoracic impedance from about 20 to about 200 ohms.

Abstract: A system for assisting a rescuer in providing resuscitative treatment to a victim is described. An example of the system includes a processor configured to detect compression waveform features characteristic of manual chest compressions, automated chest compressions, and mechanically assisted active compression-decompression (ACD) chest compressions, an output device communicatively coupled to the processor, and a motion sensor, communicatively coupled to the processor and configured to generate signals indicative of motion of the victim's chest during chest compressions. The processor is further configured to receive the signals indicative of the motion of the chest, generate a compression waveform based on these signals, identify the compression waveform as one of a manual, an automated, and a mechanically assisted ACD chest compression waveform based on compression waveform features in the compression waveform, and control the output device to selectively provide chest compression feedback to the rescuer based on the identified compression waveform.
