Defibtech Announces a Worldwide Voluntary Recall of Lifeline and ReviveR Automated External Defibrillators. The self-test software for these devices may allow a self-test to clear a previously detected low battery condition. If this situation occurs, the operator may be unaware of the low battery, and the device may be unable to deliver a defibrillation shock, which could result in failure to resuscitate a patient.
