In the past two years, sudden death caused by acute heart attack often appears in our sight, some people even before waiting for an ambulance or already on the way to the hospital has passed away. In fact, after the occurrence of acute heart attack, there are 3 hours of “golden time”, such as the correct first aid, can completely minimize the mortality rate. On the contrary, any one of the wrong first aid method, will aggravate the burden on the heart, and even lead to death! The dreaded heart attack, why is it fatal? Heart attack is acute myocardial infarction, which is the most serious type of coronary heart disease. The heart muscle, in the absence of blood supply, the cells die quickly. Once dead, they do not regenerate! If our body is compared to a car, the heart is the engine, the coronary arteries are the oil pipeline of the engine, coronary arteries, if because of blood clots are completely blocked, the heart muscle has no oil supply, then acute myocardial infarction will occur, and serious and even lead to the engine scrapped (fatal). Therefore, rescue heart attack patients, every minute is valuable, before the arrival of the emergency vehicle, the following these backward help, we can not help! “Helping” practice one, up to do cardiac resuscitation Wrong way: heart attack patients onset of chest pain on the ground, encountered this situation, under panic may think of the drama of the TV, with chest compressions to patients to do cardiac resuscitation. Reason: Chest compressions are for cardiac arrest, the first condition is that the patient is in a state of unconsciousness, weak breathing and pulse can not be felt, if the chest compressions on a conscious person, it may be counterproductive. Outpatient clinic has encountered because of the pressure method is not right (technique and force is not right), resulting in patients with rib fractures. Life-saving knowledge: 1, recognize the patient’s state: if Ta has been unconscious, should not be called, breathing weak, can not feel the pulse, before cardiac resuscitation (chest compressions and mouth-to-mouth artificial respiration), and has been adhering to the doctor to the field. 2, master the correct technique: every minute in the middle of the chest (the midpoint of the Mimi line) 100 times, the depth of pressure at least 5 centimeters, can not be randomly pressed. “Helping” second: immediately pick up the patient, feeding water Wrong way: some people will be in a hurry to help the patient up and sit down, feed two mouths of water, pat the back. Doing so will kill! Reason: the heart is constantly working every minute and every second, it is the whole body is the most need for blood supply. Acute myocardial infarction, the heart blood vessels are themselves ischemic, at this time if the patient to stand or sit up, the tired heart also have to spend more effort to other places to supply blood, to the heart of the blood will naturally be less. It is best to recline at this time. (To prevent heart failure in patients with acute myocardial infarction, do not lie completely flat!) Life-saving tips: Just let the patient lie on his/her back, stay calm, and keep calling out the patient’s name. Drink less water and keep warm to prevent choking due to vomiting. “Help” of the third: messy to nitroglycerin Wrong way: patients with sudden heart attacks, many family members are particularly anxious, will immediately give the patient to eat nitroglycerin, but not everyone can eat, can not eat with water, and can not eat several tablets continuously! Reason: eating nitroglycerin continuously for a short period of time is a very dangerous thing and does not reduce the mortality rate. It may make the blood pressure drop, and at this time then waste time in observing the effect after taking the medicine (and also give the medicine continuously), it is easy to miss the best time to rescue! (If the blood vessel is blocked for more than 20 minutes, the heart muscle will become necrotic. The larger the area of necrosis, the higher the mortality rate). Life-saving tip: Measure your blood pressure before taking the medicine! If your blood pressure is already below 90/60mmHg before taking the medicine, or if it is higher than this value but significantly lower than the usual blood pressure, then you should not use nitroglycerin, and you should rush to the hospital. Tips: Why can’t I take it with water? Nitroglycerin swallowed with water is not only slow to take effect, the drug will also be decomposed by the liver, the absorption rate is only 8%, which can not play a role in emergency. If the nitroglycerin at home is a tablet, put it directly under the tongue, do not swallow; if it is a spray, spray it under the tongue. Sublingual sublingual nitroglycerin, 5 ~ 10 minutes after another piece (repeat times can not be more than 3 times), if still can not alleviate the symptoms of chest pain or even aggravation, need to immediately call 120 waiting for emergency. If there is no nitroglycerin, you can also take fast-acting heart pills. Aspirin, clopidogrel and other drugs, it is best not to use yourself. “Helping” No. 4: patients go to the hospital alone Wrong way: after a heart attack, some patients try to go to the hospital by themselves, or even drive to the hospital, this practice commits a heart attack treatment taboo! Reason: blindly move after a heart attack, will aggravate myocardial ischemia, cardiac arrest may occur at any time. At this time if there is no companion around, it is very easy to miss the golden time of treatment. Driving to the hospital by yourself is even more dangerous! Life-saving knowledge: do not hesitate to call 120, wait for the ambulance crew to come, and actively cooperate with the treatment! Before the ambulance arrives, do these 4 steps! Step 1: Allow the patient to stabilize his/her mood, lie down quietly and rest, and avoid any stimulation. Step 2: If you always have oxygen at home, let the patient inhale oxygen quickly, 3 ~ 5 liters per minute. Step 3: After measuring the blood pressure, put 1 tablet of nitroglycerin under the patient’s tongue, and then another tablet after 5-10 minutes (the number of repetitions should not be more than 3 times). If you still can’t get relief, you need to call 120 emergency immediately. Step 4: While waiting, always observe the patient’s status and prepare for CPR.
