Introduction
Current resuscitation guideline recommends that automated external defibrillator (AED) should never be placed in the analysis mode during transport because the movement of the vehicle can interfere with rhythm assessment. To date, no direct comparison of the AED performance at the scene and in a moving ambulance has been made. The aim of this study was to determine the intensity of vibration in a moving ambulance and to evaluate the influence of movements during transport on AED performance.
