MB: FDA is alerting users of certain Powerheart and CardioVive automated external defibrillators that these devices may malfunction unexpectedly. This can cause a failure to deliver the electric shocks that are needed to treat sudden cardiac arrest or arrhythmias.
AR: The manufacturer, Cardiac Science Corporation, has received multiple complaints that these devices have malfunctioned, and that their self-test features may not show that there's anything wrong. Before each use, operators are supposed to check for a green light on the front of the AED that shows that the device is rescue-ready. But the light may come on even when certain electronic components inside the device have failed. About 300,000 Cardiac Science G3 series Powerheart and CardioVive AEDs are affected by this problem worldwide. They were manufactured between August 2003 and August 2009. FDA recommends that users contact Cardiac Science Corporation immediately to arrange for repairs or replacement.
MB: Until the company repairs or replaces the affected devices, FDA recommends that users switch to alternate AEDs if they're available, or that they consider obtaining another AED. If an alternate AED isn't available, trained responders should use manual defibrillators. If a manual defibrillator isn't available, responders should use the Powerheart or the CardioVive AEDs, since they may still be able to deliver the necessary shock.
AR: In the home or in public places, FDA recommends continuing to use these devices if an alternate AED isn't available. That's because the consequences of not trying to defibrillate a patient outweigh the risk that the AED may fail.
