[Posted 09/11/2008] Physio Control, Inc., issued a recall of LifePak CR Plus Automated External Defibrillators (AED), used by emergency or medical personnel to treat adults in cardiopulmonary arrest. The product was recalled because the AED instructs the responder by voice prompts to press the shock button which is not visible because it is covered, thereby making the responder unable to provide shock therapy. The AED device should be removed from service, or the manufacturer-provided diagram should be consulted to remove and discard the shock button cover. Read more from the FDA.
