Abstract: A defibrillation training system (10) is disclosed for use in training individuals in the proper positioning of defibrillation electrodes on a patient. The system includes a pair of training electrodes (12), each of which includes a permanent magnet (40). The training electrodes are attached to a manikin (14) at two electrode placement sites (42 and 44) provided with arrays (46 and 48) of Hall-effect sensors. The magnetic field produced by the permanent magnet in each electrode is sensed by the corresponding array, allowing an electrode placement monitor (16), attached to the manikin, to determine the electrodes' positions. The placement monitor then determines whether any adjustments in the electrodes' positions are required and prompts the individual being trained accordingly.
