Abstract
A system for managing care of a person receiving emergency cardiac assistance includes one or more capacitors arranged to deliver a defibrillating shock to a person; one or more electronic ports for receiving a plurality of signals from sensors for obtaining indications of an electrocardiogram (ECG) for the person; and a patient treatment module executable on one or more computer processors using code stored in non-transitory media and 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 mathematical computation applied to a vector value defined by signals from at least two of the plurality of signals.

22. A system for managing care of a person, the system comprising:
-
an external defibrillator, configured to monitor electrocardiogram (ECG) data from a person receiving emergency cardiac assistance, the ECG data defining a vector from multiple ECG signals; and one or more processors configured to perform operations comprising; performing a vectorized mathematical transform of the ECG data that defines the vector from a time domain to a frequency domain using a window in the time domain, determining a likelihood of future defibrillation shock success using at least the mathematical transformation, and affecting control of the external defibrillator based on an identification of whether a present defibrillation shock will likely be effective. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51)

52. A non-transitory machine-readable storage device for managing care of a person, the machine-readable storage device storing instructions that are executable by one or more processors to perform operations comprising:
-
monitoring electrocardiogram (ECG) data from a person receiving emergency cardiac assistance, the ECG data defining a vector from multiple ECG signals; performing a vectorized mathematical transform of the ECG data that defines the vector from a time domain to a frequency domain using a window in the time domain; determining a likelihood of future defibrillation shock success using at least the mathematical transformation; and affecting control of an external defibrillator based on an identification of whether a present defibrillation shock will likely be effective.
