The FDA and Welch Allen notified healthcare professionals and consumers of a nationwide Class I recall of 14,054 AED 10 and MRL JumpStart external defibrillators manufactured between October 3, 2002 and January 25, 2007. These devices may experience low energy shock, unexpected device shutdown, and/or susceptibility to electromagnetic noise interference. If such issues arise, it may prevent defibrillation of a patient in cardiac arrest and could lead to death. Class 1 recalls are the most serious type of recall and involve situations in which there is a reasonable probability that use of the product will cause serious injury or death.
