The success criteria of a simulated defibrillator mainly lie in three aspects: the standardization of operation, the accuracy of judgment, and the authenticity of defibrillation effect.

Firstly, during the usage process, the operator should be able to accurately identify the type of arrhythmia and determine whether defibrillation is needed, demonstrating a mastery of first aid knowledge.

Secondly, the operation process should be standardized, including the correct pasting position of the electrode sheet, energy selection, response to voice prompts and the implementation of safety warnings, to ensure that the defibrillation process complies with clinical standards. At the same time, trainees should confirm that "no one has been in contact with the patient" before defibrillation and accurately press the defibrillation button after the equipment prompts. Successful defibrillation training should be able to restore the model's simulated heart rhythm from abnormal to normal, with the device showing "cardioversion successful" or vital signs stabilizing.

In addition, trainees are required to perform cardiopulmonary resuscitation and vital sign monitoring immediately after defibrillation, demonstrating a complete sense of first aid and operational coordination. The successful training of the simulated defibrillator not only verified the operator's technical proficiency, but also tested their clinical judgment ability and teamwork level.
