2. Attach the electrodes to the patient's chest and place them firmly in place. Generally speaking, the two electrode plates are attached to the upper right chest and the left side of the left nipple of the left chest, the specific position can refer to the drawing on the AED case and the picture on the electrode plate instructions. There are also AEDs with integrated electrode plates, such as the ZOLL AED Plus, which will be installed at the Beijing Olympic Games.
3. Insert the electrode plate plug into the jack of the AED's main unit.
4, start to analyze the heart rhythm, defibrillation when necessary, press the "analysis" button (some models in the insertion of the electrode plate will sound a voice prompt, and automatically start to analyze the heart rate, in the process, please do not touch the patient, even if it is a slight touch may affect the analysis of the AED), the AED will start to analyze the heart rate. The AED will start to analyze the heart rate. After the analysis, the AED will issue a recommendation on whether to defibrillate or not. When there is a defibrillation indication, do not contact the patient, and tell anyone else in the vicinity to stay away from the patient, and the operator will press the "discharge" button to defibrillate.
5. If effective perfusion is not restored after defibrillation, perform 5 cycles of CPR. After defibrillation, the AED will analyze the rhythm again, and if effective perfusion is not restored, the operator should perform 5 cycles of CPR, then analyze the rhythm again, defibrillate, and perform CPR, and repeat the process until emergency personnel arrive.
