Abstract
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.
Claims37
A system for managing care of a person receiving emergency cardiac assistance, the system comprising:
- 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;
- and
- 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.
A method for managing care of a person receiving emergency cardiac assistance, the method comprising:
- monitoring, with an external defibrillator, electrocardiogram (ECG) data from a person receiving emergency cardiac assistance;
- determining whether a prior defibrillation shock occurred;
- determining a likelihood of future defibrillation shock success using at least the ECG data;
- based at least in part on the determination of whether the prior defibrillation occurred, modifying the calculation of the chance of defibrillation shock success;
- and
- affecting control of the external defibrillator based on the identification of whether a present defibrillation shock will likely be effective.
