Family sudden heart attack measure one, timely identification of heart attack. The typical symptom of heart attack is angina pectoris in the middle or left of the middle of the sternum, with a sense of near death and pressure, which can last for 5-15 minutes or more. Others will be accompanied by sweating and nausea. Generally speaking, if chest pain persists for 20 minutes without relief, you should be highly suspicious of a heart attack, and you should be alert for more than 5 minutes. In addition, sometimes heart attack also presents atypical symptoms, such as stomachache, toothache and sore throat, which are very easy to be ignored. When the above symptoms appear, the patient himself and his family should be extra vigilant, and it is best to send them to the doctor immediately, and never endure them. Family members of sudden heart attack measure two, immediately call the emergency number. One quarter of the patients will not call the emergency number 120 in the first place, but call their own family members and wait for them to arrive before calling 120, thus delaying the rescue time. But in fact, there are many disadvantages of sending the patient to the hospital by yourself. First of all, randomly moving patients or patients walking on their own will increase the out-of-hospital mortality rate, on the contrary, if you call the emergency number, the doctor will instruct the patient to help himself first on the way to come, and the process of transporting the patient can also carry out early diagnosis and treatment; secondly, many people do not understand the situation of the hospital, the hospital sent to may not have the ability to save the heart attack, and even if they have the ability, the hospital may not do a good job of preparing personnel, equipment and beds, thus delaying the treatment. This delays treatment. The significance of calling the emergency number is that the hospital can quickly start a targeted emergency green channel to grab life-saving time. Family sudden heart attack measure three, calmly waiting for help. If the patient has a history of coronary heart disease, suspected heart attack, you can take nitroglycerin, aspirin and other drugs, but if there is no medical history or is not clear about the patient’s condition, it is best not to give the patient random medication. It is best to keep the patient lying flat, quiet and unstimulated. If possible, it is best to administer oxygen, and if there is really no oxygen, open the windows so that the patient can get an adequate supply of oxygen. After a heart attack, one of the worst scenarios is ventricular fibrillation, which may lead to sudden death. At this time, it is best to keep the patient’s airway open, and do chest compressions and artificial respiration to prevent brain hypoxia, so as to avoid rapid brain cell death.
