AED is a medical emergency equipment that has emerged in recent years.AED is the abbreviation of Automated External Defibrillator, also known as Automatic Extracorporeal Defibrillator, Auto Electric Defibrillator, Automated Defibrillator, Cardiac Defibrillator, and Fool's Shocker. In the case of a dangerous or sudden illness, people have four minutes of prime first aid time. If you make good use of that time, it could work a great miracle.
To turn on the AED, open the lid of the AED and operate it based on visual and audible cues.
Apply the patient electrodes to the patient's chest in a suitable location so that they are in close contact with the patient electrodes. Generally, two pieces of electrode plates are attached to the right chest and the left chest on the outside of the left nipple, the specific position can refer to the schematic diagram on the AED case and the instructions on the electrode plates. Insert the electrode plate plug into the AED main unit jack.
Starting with analyzing the heart rhythm and defibrillation if necessary, press ? Analyze? button (some models will emit an audible tone after inserting the electrode board and automatically start to analyze the heart rate, during the analysis, please do not touch the patient, even a slight touch may affect the analysis of the AED), the AED will start to analyze the heart rate.The AED will make a recommendation on whether to defibrillate or not after the analysis.When there is an indication for defibrillation, do not contact the patient, and also inform other people in the vicinity to stay away from the patient, by the The operator presses ? The operator presses the "Discharge" button. button to defibrillate.
Five cycles of CPR (cardiopulmonary resuscitation) were performed after one defibrillation without restoration of an effective perfusion rhythm. After defibrillation, the AED will analyze the heart rhythm again, and if effective perfusion rhythm is not restored, the operator should perform 5 cycles of CPR. By turning on the power and placing the patches on the patient, the AED can shock a patient in cardiac arrest, which, together with cardiopulmonary resuscitation (CPR), can effectively improve the success rate of first aid until the arrival of the paramedics.
In order to effectively resuscitate a cardiac arrest patient, the most important thing is to utilize artificial cardiac massage to maintain blood circulation, provide oxygen to the vital organs of the body, and utilize defibrillation with electric shock to restore the normal operation of the heart for CPR and AED resuscitation.
Sudden cardiac death has an annual incidence of more than 540,000 cases in China, which is equivalent to about one death per minute. According to statistics, 70% of emergencies such as sudden death occur outside the hospital at home, public **** places, etc., and 65% of emergencies occur within 15 minutes of onset. If the first witness has first aid skills, and within 4 minutes of timely implementation of CPR, the survival rate of up to 50%, more than this time, each delay of 1 minute, the success rate of resuscitation will drop 7% to 10%. Because of traffic conditions and other reasons, emergency vehicles in 4 minutes to the scene is very difficult, and AED can make up for this deficiency. The current series of policies introduced in China is accelerating the layout of AEDs in major transportation hubs.
