Cardiac Science Corporation and FDA notified healthcare professionals and consumers of a recall because the automated external defibrillator (AED) may not be able to deliver therapy during a cardiac resuscitation attempt, which may lead to serious adverse events or death. These AEDs were manufactured in a way that makes them potentially susceptible to failure under certain conditions. Each of the approximately 12,200 devices affected in this recall can be confirmed at the Cardiac Science Web site, www.cardiacscience.com/AED195. The affected AEDs were manufactured or serviced between October 19, 2009 and January 15, 2010 and include the following models – Powerheart 9300A, 9300E, 9300P, 9390A, 9390E, CardioVive 92532 and CardioLife 9200G and 9231. Each affected AED should immediately be removed from service since it may not deliver the expected therapy.
