DEFIBRILLATOR WITH PROTOCOL FOR SELECTIVELY INTERRUPTING CPR

摘要

An automated external defibrillator (AED) (10) having a treatment decision processor (28) 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 (10) thus enables an improved rescue protocol.

主权项

1. A defibrillator for detecting a shockable heart rhythm during CPR comprising:
a high voltage circuit for delivering electrotherapy; an ECG front end circuit coupled to a source of ECG signals; a controller communicatively coupled to the ECG front end circuit, comprising
a treatment decision processor responsive to the ECG signals which acts to estimate the likelihood of a shockable rhythm existent during a CPR period and which determines whether CPR should be interrupted prior to the end of the CPR period to deliver electrotherapy; and a user interface, responsive to the controller determination, which provides an output instruction to stop CPR and a subsequent output instruction to deliver electrotherapy through the high voltage circuit.
