Shock determination based on prior shocks

摘要

A system for managing care of a person receiving emergency cardiac assistance is disclosed that includes one or more capacitors for delivering a defibrillating shock to a patient; one or more electronic ports for receiving signals from sensors for obtaining indications of an electrocardiogram (ECG) for the patient; a patient treatment module executable on one or more computer processors to provide a determination of a likelihood of success from delivering a future defibrillating shock to the person with the one or more capacitors, using (a) information about a prior defibrillating shock, and (b) a value that is a function of current ECG signals from the patient.

1. An external defibrillator system for managing care of a person receiving emergency cardiac assistance, the system comprising:
one or more capacitors for delivering a defibrillating shock to the person; one or more electronic ports for receiving signals from sensors for obtaining indications of an electrocardiogram (ECG) for the person; a patient treatment module executable on one or more computer processors to provide a determination of a metric indicative of a likelihood of success from delivering a future defibrillating shock to the person with the one or more capacitors, using (a) information about an indicator of success associated with a prior defibrillating shock, the indicator determined based on a segment of ECG waveform corresponding to a time period following application of the prior defibrillating shock, and (b) a value that is a function of current ECG signals from the person; and an output mechanism comprising a visual display that is configured to display one of multiple possible indications that each indicate a degree of the likelihood of success from delivering a defibrillating shock to the person with the one or more capacitors.
