Open the AED, open the cover of the AED, and follow the video and audio prompts.
Stick the patient electrode on the appropriate position of the patient's chest to make it closely contact with the patient electrode. Generally, two electrode plates are attached to the outer side of the left nipple of the right chest and the left chest respectively. Please refer to the schematic diagram on the AED housing and the instructions on the electrode plate for the specific location. Insert the electrode plate plug into the AED host jack.
Start by analyzing the heart rhythm, defibrillation if necessary, and press? Analysis? Key (some models will have a sound prompt after inserting the electrode plate, and automatically start to analyze the heart rate. During the analysis, please don't touch the patient, even a slight touch may affect the analysis of AED), AED will start to analyze the heart rate. After the analysis, AED will make suggestions on whether to perform defibrillation. When there are indications for defibrillation, do not contact with the patient, inform others nearby to stay away from the patient, and the operator presses? Discharge? Defibrillation key.
After defibrillation, the effective perfusion rhythm did not recover, and cardiopulmonary resuscitation (CPR) was performed for 5 cycles. After defibrillation, AED will analyze the heart rhythm again. If the effective perfusion heart rate does not recover, the operator should perform five cycles of cardiopulmonary resuscitation. As long as the power is turned on and the patch is attached to the patient, the patient with cardiac arrest can be shocked. With cardiopulmonary resuscitation (CPR), the success rate of first aid can be effectively improved until the arrival of medical staff.
In order to effectively rescue patients with cardiac arrest, the most important thing is to use artificial heart massage to maintain blood circulation, provide oxygen for important organs of the body, and use electric shock defibrillation to restore the normal operation of the heart, for cardiopulmonary resuscitation and AED first aid.
The incidence of sudden cardiac death in China exceeds 540,000 cases every year, which is equivalent to about 1 death per minute. According to statistics, 70% of sudden death and other emergencies occur at home, public places and other hospitals, and 65% of emergencies occur within 15 minutes of onset. If the first witness has first-aid skills and carries out cardiopulmonary resuscitation within 4 minutes, the survival rate can reach 50%. After this time, for every delay of 1 minute, the success rate of rescue will drop by 7% to 10%. Because of traffic conditions and other reasons, it is difficult for ambulances to arrive at the scene within 4 minutes, and AED can make up for this deficiency. At present, a series of policies issued by the state are accelerating the layout of AEDs in major transportation hubs.
