September 8th is the “World First Aid Day” in 2018. The Red Cross and the Red Crescent International Federation will designate the second Saturday of September each year as “World First Aid Day”. From 2000 It has been the 19th “World First Aid Day” to start this year. This year’s September 8th is also the “white dew” of the Chinese solar terms, which means that it will officially enter the autumn. At this time, the temperature has begun to fall, the weather is repeated, and the temperature difference between the weather is large. For patients with coronary heart disease, it is very important to treat timely treatment in time after the disease. Experts remind that the first aid of coronary heart disease should not be “superstitious” nitroglycerin. In some cases, emergency administration is delaying the timing of treatment. Correct rescue is very important.
The “first aid trilogy” when the coronary heart disease occurs
When encountering a crown heart disease, it is best to rescue on the spot. The first principle of first aid is to maintain calmness and orderly manner; the second is to dial 120 emergency calls in time when implementing in -site first aid, and maintain communication with professional first aid personnel to understand what they can do at the scene to treat patients.
For patients with crown heart disease, they should first stop the activity immediately, stay in bed or lie on a flat ground to rest, do not walk back and forth or move the patients; if the patient wears a shirt with a collar, you should immediately unlock the clothes buckle. , Ensure that patients breathe smoothly, try to soothe patients; pay attention to ensure that the patients are ventilated around and have sufficient oxygen.
In cases of conditions, you can ask or find out the patient -related medical history information, as well as whether there are cure drugs with you. In the case of treating drugs, take first aid in time. Generally, the first choice of the tongue contains nitroglycerin tablets, and it can also help use some quick -acting savior pills.
When the attack lasts for more than half an hour or after taking the medicine, it still has not been relieved, especially the signals that have some serious situations, such as difficulty breathing, sweating, vomiting, cold hands and feet, blurred consciousness, etc., you should immediately call 120 emergency calls, early early, early early, early, early, early, early, early, early Take it to the hospital for treatment.
Don’t be superstitious when you first aid
In the first aid of coronary heart disease, it is very important: there are foreseeable conditions for possible serious circumstances, and acute myocardial infarction may occur. Do not take nitroglycerin as “universal medicine”, and take it one after another.
It is mainly caused by acute short -term myocardial ischemia and hypoxia on the basis of coronary atherosclerosis. When the blood flow of coronary arteries decreases and the myocardial oxygen demand is increased; the causes are mostly cold, fatigue, and emotional excitement. Incident; after rest and serpentin sliced glycerin tablets, it can be reduced.

The myocardial infarction is based on severe coronary atherosclerosis. Throstly formation leads to blood vessel occlusion, blood flow interruption, severe myocardial ischemia and hypoxia, and some myocardial necrosis occur. Can’t reduce.
Therefore, when chest pain is not alleviated for 1 to 2 times, and chest pain and dyspnea continue for more than half an hour, they should be regarded as a risk aura of myocardial infarction. They should be quickly sent to the hospital for further diagnosis and rescue. Otherwise, blood pressure will decrease due to vascular dilation, which will increase myocardial ischemia and hypoxia; accompanied by this, it can also increase the heart rate faster due to the decrease in blood pressure, which will cause the increased myocardial oxygen consumption Essence
