A defibrillator (AED) and method for using a defibrillator using two different ECG analysis algorithms which work sequentially to improve the accuracy of AED shock decisions. A first algorithm, such as (ART), is particularly suited for analysis in the presence of CPR periods. A second algorithm, such as (PAS), is particularly suited for analysis during hands-off periods. The AED switches algorithms depending on the period and on the current analysis of the cardiac rhythm. The inventions thus provide an optimized ECG analysis scheme in a manner that improves the effectiveness of the rescue, resulting in more CPR 'hands-on' time, better treatment of refibrillation, and reduced transition times between CPR and electrotherapy.

Automated external defibrillator (AED) with dual ECG analysis algorithms

A defibrillator and method for using a defibrillator which adopts an ECG analysis algorithm that can detect a cardiac arrhythmia in the presence of noise artifact induced by cardio pulmonary resuscitation (CPR) compressions. The apparatus and method provides both of a continuous and scheduled mode of operation for interleaving periods of CPR with electrotherapy, in a manner that improves the effectiveness of the rescue, resulting in more CPR 'hands-on' time, better treatment of refibriUation, and reduced transition times between CPR and electrotherapy.

Defibrillator with scheduled and continuous modes of operation

A defibrillator (AED) and method for using a defibrillator incorporates a user activated button truncates an ongoing ECG analysis to immediately perform a different defibrillator-related function. The AED may use two different ECG analysis algorithms having different sensitivities to a shockable cardiac rhythm, and a press of the button may automatically shift from a first algorithm to a second algorithm with the higher sensitivity. The button may also allow truncation of ongoing analysis and CPR for immediate preparation for electrotherapy.
