A serious software problem with two models of automatic external defibrillators has led their manufacturer to recall thousands of the devices distributed worldwide.
Defibtech said problems with the software in its Lifeline AED and ReviveR AED models may fail to flag a previously detected low battery during some tests. If that occurs and the battery is indeed drained, the device may not be able to deliver the defibrillation shock needed to restart a person's heart.
The recall affects all Lifeline AED and ReviveR AED automatic external defibrillators that have software versions 2.002 and earlier, the company said. The company also said it would provide a free software upgrade within the next 10 weeks. The upgrade can be installed by customers without returning the devices.
