Claim:
1. A defibrillator comprising: an ECG front end circuit coupled to a source of ECG signals; and a controller communicatively coupled to the ECG front end circuit, comprising an ECG data analysis circuit responsive to the ECG signals which analyzes ECG data to determine whether a shock is recommended or a shock is not recommended; and a treatment decision processor responsive to the ECG signals which acts to estimate a first probability of resuscitation from a shock and a subsequent probability of resuscitation from a shock; and a defibrillator mode circuit responsive to the ECG data analysis circuit and the treatment decision processor which is operable to set the defibrillator to a shock mode or a CPR mode of operation and which is further operable to change a CPR mode of operation from one of a plurality of CPR modes of operation to another one of a plurality of CPR modes of operation based on a change from the first probability to the subsequent probability, wherein the plurality of CPR modes of operation comprises a compressions-only mode and a compressions-plus-breaths mode of operation, and further wherein the defibrillator mode circuit changes the CPR mode of operation from a compressions-only mode to a compressions-plus-breaths mode of operation if the subsequent probability is lower than the first probability.
