1. Turn on the AED, open the lid of the AED, and follow the visual and sound prompts (some models need to press the power first).
2. Attach the electrode to the patient and place the electrode tightly on the appropriate position on the chest of the patient.
3. Insert the electrode plate plug into the AED main unit jack.
4. Start analyzing the heart rhythm, defibrillation if necessary, press the “Analyze” button (some models will give voice prompt after inserting the electrode plate, and automatically start analyzing the heart rate, do not touch the patient during this process, even slight touch may affect the analysis of the AED), and the AED will begin to analyze heart rate. After the analysis is completed, the AED will issue recommendation for defibrillation. When there is defibrillation indication, do not touch the patient and tell anyone nearby to stay away from the patient, and the operator will press the “discharge” button to defibrillate.
5. The effective perfusion rhythm was not restored after one defibrillation, and 5 cycles of CPR were performed. After defibrillation, the AED will analyze the heart rhythm again. If the effective perfusion rhythm is not restored, the operator should perform 5 cycles of CPR, and then analyze the heart rhythm, defibrillation, CPR again and again until the arrival of emergency personnel.
