A method for delivering electrotherapy from a defibrillator includes the steps of providing a source of patient ECG signals received during a CPR period, estimating from the patient ECG signals the likelihood of a shockable rhythm existent during the CPR period, and determining whether CPR should be interrupted prior to the end of the CPR period to deliver electrotherapy based on the estimating step. Based on the determining step, the defibrillator may then provide an output instruction to stop CPR. The AED () thus enables an improved rescue protocol.

Defibrillator with protocol for selectively interrupting CPR

An automated external defibrillator (AED) () having a treatment decision processor () is described which follows a 'shock first' or a 'CPR first' rescue protocol after identification of a treatable arrhythmia, depending upon an estimate of the probability of successful resuscitation made from an analysis of a patient parameter measured at the beginning of the rescue. The invention may also follow different CPR protocols depending on the estimate. The invention also may use the trend of the measured patient parameter to adjust the CPR protocol either during a CPR pause or after the initial CPR pause. The AED () thus enables an improved rescue protocol.

Defibrillator with dynamic ongoing CPR protocol

An automated external defibrillator (AED) () having a treatment decision processor () is described which estimates the probability of successful resuscitation made from an analysis of a patient parameter measured in the presence of CPR artifact. The invention may also adjust its analysis protocol and guidance outputs depending on a comparison of the estimate with a subsequent shock analysis. The invention also may use the trend of the measured patient parameter to adjust the CPR protocol either during a CPR pause or after the initial CPR pause. The AED () thus enables an improved rescue protocol.
