The first step in using an aed to resuscitate an injured person is to ensure the safety of the rescuer.
Automated external defibrillator (AED), also known as automated external defibrillator (AED), automatic defibrillator (AED), automatic defibrillator (ADF), cardiac defibrillator (CDF), and dumb defibrillator (DDF), is a portable medical device that diagnoses specific cardiac arrhythmia and defibrillates the heart with electric shocks, which can be used by non-specialized personnel to rescue cardiac arrest patients.
In cardiac arrest, defibrillation and cardiopulmonary resuscitation (CPR) using an automated external defibrillator (AED) is the most effective way to stop sudden death only in the "golden four minutes" of the optimal resuscitation time. After getting the AED, the first principle is to ensure the safety of the rescuer first, look around, pay attention to the presence of vehicles, etc., if there is a risk factor exists, to transfer the patient to a safe environment.
AED use steps
1, turn on the AED, open the cover of the AED, based on visual and sound prompts to operate (some models need to press the power first). Patch position.
2. Patch the electrodes to the patient, and tightly attach the electrodes to the patient's chest at the appropriate location. Generally speaking, the two electrode plates are pasted on the upper right chest and the outer left nipple of the left chest, and the specific position can be referred to the drawing on the AED case and the picture description on the electrode plate. There are also AEDs with integrated electrode plates, such as the ZOLL AED Plus, which will be configured at the 2022 Beijing Winter Olympics.
3. Insert the electrode plate plug into the AED's main jack.
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 analyzing the heart rate.
After the analysis is complete, the AED will issue a recommendation on whether or not to defibrillate. When there is an indication for defibrillation, 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 heart rhythm again, and if effective perfusion is not restored, the operator should perform 5 cycles of CPR, then analyze the heart rhythm again, defibrillate, and perform CPR, and repeat the process until the emergency personnel arrive.
