As the rhythm of life continues to accelerate, the incidence of Sudden Cardiac Death is getting younger and younger, the death of young people is becoming more and more common. It may happen in our daily life, possibly in campus or in the lab, or even in our own home. Therefore, every citizen should learn first aid knowledge and skills. In China, there are as many as 550,000 sudden cardiac deaths each year, but the out-of-hospital survival rate is less than 1%. The average bystander's CPR As the pace of life continues to accelerate, the incidence of cardiac arrest is increasing, these accidents are likely to happen in our side one day.Therefore, every individual should learn first aid knowledge and skills.At present, the average rate of bystander CPR in China is only 4.5%, far lower than that in developed countries.Therefore, it is particularly important to train college students in cardiopulmonary resuscitation (CPR) techniques, master the resuscitation principles, standardize the operating techniques, and become proficient in the resuscitation procedures.Through the teaching process of classroom explanation, model operation and scenario simulation training, this course enables students, especially non-medical students, to master out-of-hospital cardiopulmonary resuscitation first-aid technology, further improve students' comprehensive quality and strengthen their complete consciousness.
