ISSUE: A failure on the power supply assembly can result in either "No DC power" or "No DC or AC power". A failure of DC (battery) power can result in the inability to deliver defibrillation therapy if the device will not turn on using DC (battery) power and no AC (line) power is available.
BACKGROUND: The LIFEPAK 20 and LIFEPAK 20e defibrillator/monitor is designed for use by trained medical personnel in hospitals and clinic settings to monitor patient heart rhythms and to treat patients experiencing cardiac arrest. Approximately 42,943 devices were distributed worldwide between September 16, 2002 and September 27, 2007. These devices were manufactured from July 31, 2002 to September 19, 2007.
RECOMMENDATION: All affected power supplies will be updated. Customers are advised to keep the defibrillators in service and follow recommended daily Operator Checklist steps while service updates are scheduled. See Recall Notice for contact information.
