What to do if you have myocardial infarction? First aid measures for myocardial infarction

Myocardial infarction is a disease that threatens people's lives, so it is very necessary to master the first aid measures for myocardial infarction. If a patient has a myocardial infarction, he must first be asked to rest in bed, and then quickly call 120 for emergency assistance.

1. First of all, let the elderly stay in bed and rest absolutely. Do not walk around or exert yourself at will to reduce myocardial oxygen consumption.

2. Call the emergency center as early as possible and inform the elderly person of their current condition so that rescue personnel can prepare necessary rescue equipment.

3. Provide high-concentration continuous oxygen inhalation for no less than half an hour.

4. Relieve severe pain. Take 1 to 5 tablets of Xiamen Airlines nitroglycerin tablets, each tablet should be taken 3 to 5 minutes apart. If conditions permit, intravenous nitroglycerin can be given by adding 5 to 10 ml of nitroglycerin to 500 ml of liquid and continuous drip; swallow 15 to 30 tablets of Quick-acting Heart-saving Pills; narcotic analgesics such as 50 ml of pethidine or 5 ml of morphine can be injected intramuscularly.

5. Use sedatives appropriately. Diazepam (Valium) 1 to 2 tablets orally or 10 mg intramuscularly; promethazine and phenobarbital can also be used.

6. If possible, measure blood pressure and record the heart rate and rhythm per minute for reference when the doctor arrives.

7. Before the doctor arrives, the elderly should not be left without someone by their side to observe changes in their condition at any time. If the elderly suddenly becomes cyanotic, convulses, screams, foams at the mouth, becomes unconscious, has weak and stopped breathing, and has dilated pupils, it means that they have an acute myocardial infarction with severe arrhythmias such as ventricular fibrillation, leading to cardiac arrest. At this time, Xu performed cardiopulmonary resuscitation on the patient in a race against time.

8. When the elderly person's heart rate, heart rhythm and blood pressure are stable, lift and move the elderly person gently and send them to the hospital safely for further rescue and treatment.
