Unreliable post event report from an automated external defibrillator.
Medical supervision of the use of automated external defibrillators (AEDs) is possible by the incorporation of a solid state memory system recording electrocardiography (ECG) tracings and information about the operation of the device. Since a post event report suggested inappropriate AED use erroneously, the information storage and printing processes of the Laerdal AED system were investigated. This analysis strongly suggests (yet unpredictable) incompatibilities between the software built in the solid state memory modules and the different components of the printing system. Although no problems were encountered during the resuscitation attempts, these findings may be clinically relevant because an unreliable post event report from a solid state memory module may lead to erroneous criticism of an AED user.
