The news of young people leaving due to myocardial infarction happens again and again, and I would like to inform you about a very important knowledge! How to grasp the golden first aid time? The critical moment can save your life. Let’s say the moment is 17:50, and you are driving home alone after a long day of work! You are feeling very nervous and uncomfortable…suddenly! You feel a sharp pain in your chest and it starts to spread to your arm and jaw, but the nearest hospital is probably a ways away. What’s worse is that the roads are so bad that you don’t know if you’ll make it that far? What to do? What is the first aid for a heart attack? How to grasp the golden emergency time? First of all, don’t panic, call 120, ask the doctor to come quickly or send to the hospital for emergency treatment. Immediately lie down on the ground, feet slightly elevated, strictly prohibited from walking. Aspirin 300mg chewing; or sublingual nitroglycerin tablets; or isopentyl nitrite 1, with a hand towel squeezed over the nose inhalation. If there is oxygen supply conditions, oxygen should be inhaled immediately. If the effect of the above first aid is not obvious, you should immediately seek help for mouth-to-mouth respiration and chest cardiac compression. Send it out. It may just save their life as a result!!!! Please don’t make the mistake of thinking that just because you are less than 25 or 30 that you are not having a heart attack, due to today’s changing lifestyles, heart attacks can occur in people of all age groups.
