In the early hours of the 9th, a member of the Beijing swimming team, who had won two gold medals at the first Youth Games, died suddenly in his dormitory, news that we deplore! Sudden death of athletes is not an isolated case, what exactly is the reason for the occurrence of one tragic event after another? It has been reported in our literature that 87.7% of sudden deaths occur outside of hospitals. An out-of-hospital onset means that patients do not receive timely emergency care from medical professionals after the onset, and there is a lack of CPR skills among the general public. This is one of the major reasons why the incidence of sudden death is so high. There are two main types of sudden death, namely cardiac and non-cardiac. The athlete just attended a physical examination with all his teammates on October 28 and got all normal results. So what can be initially concluded is that Qing Wenyi’s sudden death was non-cardiogenic. The sudden death of an athlete is easily associated with “sudden athletic death”, but the athlete died suddenly in the early morning while sleeping, how can this be explained? Our conventional consciousness of “sudden athletic death” is in the sports field, in fact, “sudden athletic death” is generally divided into two situations, the first is in the sports field problems, and another is after the exercise in 6 hours, or even 24 hours, there are There is a possibility of death. For the “sudden sports death”, not as long as the movement will occur, is generally triggered by specific conditions formed. It is understood that the athlete 8 only in the afternoon just and teammates swam less than 1000 meters of relaxation swim, for athletes, in general, the intensity of the exercise does not reach the intensity of the trigger. So “sudden death” is necessarily a problem with the physical condition of the athlete, probably in the cardiovascular system, more difficult to detect. In the early morning of the 9th, the team was awakened by the athlete’s shout, found unresponsive and then go to the team doctor, the team doctor after diagnosis found that the situation is not good and then called 120 ambulance, the ambulance arrived, the doctor only to implement emergency rescue, the process of waiting anxiously in the middle we can imagine. If we can get effective resuscitation measures in the first time, perhaps we can save a fresh life. Therefore, it is undeniable that this incident has once again sounded an alarm that our national awareness of first aid and the popularity of first aid capabilities are very lacking. Once cardiac arrest occurs, if not resuscitated immediately and in time, it will cause irreversible damage to the patient’s brain and other important human organs and tissues after 4 to 6 min, so cardiopulmonary resuscitation after cardiac arrest must be performed immediately at the scene to win the most valuable time for further resuscitation until the life of the patient in cardiac arrest is saved. The main measures are: call the medical emergency number immediately, while keeping the patient lying down, and perform continuous cardiac compressions and artificial respiration for the patient, with 30 compressions and 2 mouth-to-mouth respirations for the patient. The CPR operation should not be stopped, and the patient may have a chance of survival if he or she persists until the arrival of professional emergency personnel. It is recommended that the public take moderate intensity exercise, exercise should be measured, especially when athletes or participate in competitive competitions, do not be forced to pressure or too strong to win, safety is the first. There are studies that point out that sudden unexpected death in marathons is often in the last five kilometers. Modern sudden death of various types is becoming more and more frequent, and mostly occurs in the outdoors, if each time we have to wait until the ambulance comes and then gun to save, the survival rate of sudden death patients will be greatly reduced, it is recommended that we should actively participate in the community and the hospital organization of various first aid knowledge exercises to improve the overall first aid ability of the public.
