rest
Regardless of angina pectoris or myocardial infarction, patients should immediately stop all activities, sit down or stay in bed, and it is forbidden to run for help or walk to the hospital. If you are outdoors, you should squat down and have a rest. Because stillness can reduce the load on the heart, thus reducing the oxygen consumption of myocardium and delaying the necrosis of myocardial cells due to lack of oxygen. At the same time, relax and don't be too nervous. If you are sick in winter, you should pay attention to keep warm.
Open breathing
Smooth and effective breathing is particularly important for patients with acute coronary heart disease. Windows should be opened immediately for ventilation to keep the indoor air fresh. At the same time, untie the patient's collar and remove the vomit in his mouth in time to avoid airway obstruction caused by aspiration. Family members should also constantly comfort patients to avoid airway spasm caused by excessive tension and suffocation. If conditions permit, oxygen can be given through the nose immediately.
glonoin
People with a history of coronary heart disease should always prepare first-aid drugs. Once angina pectoris attacks, nitroglycerin 1 tablet can be taken sublingually immediately, which takes effect within about 1 ~ 2 minutes, and the drug effect lasts for about half an hour. Or take isosorbide dinitrate 1 ~ 2 tablets, which usually takes effect in 5 minutes and lasts for 2 hours.
Angina attacks can generally be relieved in a few minutes after rest and taking nitroglycerin; Otherwise we should consider the possibility of myocardial infarction. At this time, nitroglycerin tablets can be increased to 1 time, once every 3 ~ 5 minutes, or Guanxinsuhe pills can be taken orally. Some spray preparations for acute attack of coronary heart disease can also take effect in a short time. If the patient is fidgety, he can take 1 tablet orally, or pinch or acupuncture Neiguan (2 inches on the wrist transverse stripes, equivalent to his 3 fingers, and take the point between the two tendons). Of course, at the same time of the above treatment, you should call the emergency center for help quickly.
Cardiopulmonary resuscitation
The most dangerous type of coronary heart disease attack and the most common cause of death are cardiac arrest, which is usually called sudden death of coronary heart disease.
For sudden death, 4 minutes after cardiac arrest and respiratory arrest is the key time for first aid. At this time, the energy in the brain has not been exhausted, and timely on-site first aid may bring the sudden death back to life; If it takes more than 4 minutes, the brain cells can be necrotic due to severe ischemia and hypoxia, and the patient has almost no possibility of survival. Even if there is, most of them are vegetative.
These are some first-aid measures that can be taken when coronary heart disease attacks, and patients with coronary heart disease and their families can popularize this kind of knowledge. In this way, in case of emergency, you can prepare and deal with it at the first time. Of course, the best way is to do preventive work on weekdays to avoid dangerous situations.
