Abstract:
1. A method for managing care of a person receiving emergency cardiac assistance, the method comprising: monitoring, with an external defibrillator, multiple parameters of the person receiving emergency cardiac assistance; determining from at least one of the parameters, an indication of trans-thoracic impedance of the person receiving emergency cardiac care, the indication of trans-thoracic impedance representing a present impedance level across the thorax for the person receiving emergency cardiac care; determining, from at least one of the parameters corresponding to an electrocardiogram of the person receiving emergency cardiac assistance, an initial indication of likely shock effectiveness; determining, as a function of at least a combination of the indication of trans-thoracic impedance and the initial indication of likely shock effectiveness and using as separate inputs the indication of transthoracic impedance and the initial indication of likely shock effectiveness determined from the parameters corresponding to the electrocardiogram, an indication of whether a shock provided to the person receiving emergency medical assistance will be effective in terminating an arrhythmic episode; and affecting control of the defibrillator by a caregiver as a result of determining the indication of whether a shock will be effective.
