1. A method for determining an efficacy of cardiopulmonary resuscitation (CPR), the method comprising, using a processor configured to determine the efficacy of CPR, wherein the processor is associated with a patient monitor, an oximetry sensor, and an electrocardiogram (ECG) sensor, and wherein determining the efficacy of CPR comprises:

  • receiving, at the processor, a plethysmography signal from the oximetry sensor;

    receiving, at the processor, an ECG signal from the ECG sensor;

    determining a first indicator related to the efficacy of CPR based on the plethysmography signal, using the processor;

    determining a second indicator related to the efficacy of CPR based on the ECG signal, using the processor;

    combining the first indicator and the second indicator to determine a combination metric indicative of the efficacy of CPR, using the processor; and

    adjusting parameters controlling one or both of a rate or depth of compressions applied by a CPR device based on the combination metric.
