The heart does not beat, there is a special medical term called “cardiac arrest”, the heart will stop pumping blood, and the organs are due to lack of blood and oxygen and stop working, a long time will occur cell necrosis, and sudden death. One minute of cardiac arrest and the Grim Reaper is already knocking on the door! Many people think that cardiac arrest is equal to death, this is a wrong idea, in clinical sudden cardiac arrest is not uncommon, its severity is mainly considered by the time, one second of stopping we call “steal stop”, occasionally does not damage the health, mainly need to be alert to the trigger cause. Cardiac arrest of up to one minute is very dangerous, although it can not be called death, but if you can not take timely measures, the chance of death is very large, just like the film and television works we watch, the character in which suddenly pale, weak, fainting and convulsions are likely to occur in cardiac arrest, within 20 seconds people will not be unconscious, within 60 seconds people will be unconscious but there may be some physical Theoretically speaking, cardiac arrest for more than 6 minutes is already infinitely close to death, and the chance of survival is less than 4%, and patients who can survive after this time can be called miracles. Life cannot afford to wait, and first aid is a necessary skill for us! No one can say what will happen in the future, but life is always the most important. Maybe many people are not doctors and do not want to know too much medical knowledge, but I think some simple first aid is a skill that everyone should have, not for themselves, but for their parents, wives, children and friends around them, and maybe one day in the future, their lives are in your hands. After confirming that the patient is not conscious, you should use the palm root placed in the middle of the chest, depth 5-6cm, frequency control between 1.5-2 times a second, must be vertical pressure, natural rebound, the number of times in about 30 times, and then clean up the patient patient’s mouth foreign body, artificial respiration for 2 times, during the need to pay attention to elevate the patient’s chin, while pinching the patient’s nose, completely covering his mouth, smooth blowing to make the patient Chest bulge, when the patient’s chest becomes flat then blow again, and so on repeatedly. No one wants to die, accidents are accidents because they often come suddenly, it is always better to plan ahead than to mend blindly.
