For the AED to analyze accurately, the victim must be motionless. Sometimes there will be an agonal respiration (a gasping breath that can occur when the heart is stopped) that causes some movement. AEDs can recognize this extra motion and indicate "motion detected" to the operator. This warns the operator to assess carefully for extra movements from the victim or other people at the scene.
