Keywords: coronary heart disease first aid

    In China, the high incidence of coronary heart disease, but patients with coronary heart disease, including most people did not grasp the heart attack first aid. In such acute, whether the master first aid knowledge could mean the difference between life and death …
                
    Acute onset of coronary heart disease, in patients with sudden severe chest pain, sweating, and even sudden cardiac respiratory arrest. In this case, family members often panic hands and feet, whack, effective first aid not only patients, but to accelerate the death of the patient or even because of some wrong practices. The list goes on. Now, let us come to understand, acute exacerbation of coronary heart disease, and what we should and can do.
                
    Rest

    Either angina or myocardial infarction, the patient should first immediately stop all activity, sit down or rest in bed, prohibit running a cry for help or go to the hospital on foot. If outside, should situ squat rest. Still can reduce the load on the heart, reducing myocardial oxygen consumption, delaying myocardial cells hypoxia and necrosis. At the same time, the spirit should be relaxed, do not be too nervous. Such as the onset of the winter field should keep warm.
                
    Unobstructed breathing

    Smooth, effective breathing is particularly important in patients with coronary heart disease acute exacerbation. Should immediately open the window ventilation to keep indoor air fresh. Unlock the patient collar, and to clear vomit in his mouth, in a timely manner to avoid aspiration to cause airway obstruction. Family members should also continue to comfort patients, to avoid excessive tension caused by airway spasm, causing suffocation. Conditional nasal oxygen immediately.
                
    Nitroglycerin

    Coronary heart disease should be standing history of rescue medication. Once the angina attack, immediately sublingual nitroglycerin 1, will be able to work in about 1 to 2 minutes, which lasted for about half an hour. Or sublingual isosorbide dinitrate 1 to 2, generally 5 minutes work, the continuing role of the two hours.
               
    Angina attacks, usually after a few minutes rest and taking nitroglycerin can ease; otherwise, will have to consider the possibility of myocardial infarction. Nitroglycerin tablets may be increased to 1 every 3 to 5 minutes, or oral Guan Xin Su He Wan. Some acute exacerbation spray formulation for coronary heart disease (such as isosorbide esters aerosol) in a short period of time of onset. If the patient irritability, allowed an oral stability, it can also mean pinch or acupuncture Neiguan (2 inch on the wrist stripes, the equivalent of his own 3 Wang pointed acupoints between the two tendons) and other points . Of course, while performing the above, shall promptly to the emergency center for help.
                
    Cardiopulmonary resuscitation

    A type of heart attack the most dangerous and the most common cause of death was cardiac arrest, often referred to as sudden coronary death.
               
    Of a sudden death in four minutes after the cessation of the heartbeat and breathing, is the critical time of the first aid. At this time, the energy of the brain is not yet exhausted, give timely on-site first aid, may cause sudden death and back to life; If more than four minutes, brain cells can be severe ischemia, hypoxia and necrosis in patients with virtually no possibility of his survival, even if survival down, mostly vegetable.
               
    So how rescuing sudden death?

    While calling for help to the emergency center immediately patient supine board. Then for emergency treatment, according to the following steps:
               
    A. Open the airway

    Sudden death and the base of the tongue backward fall, to varying degrees, blocked the entrance to the airway, so first of all give patients clear airway. Presently in general his head and lift the chin law by rescuers at the patient’s side, with one hand placed on the patient’s forehead, press down hard, the other hand, food, middle finger placed in patients under the chin (chin), forced held up, so that the patient’s airway
    Fully open.
               
    B. artificial respiration

    Sudden death and lung collapse, and therefore need to force the first blow two breaths, observed that there are ups and downs to the chest and abdomen. Then blowing 12 to 16 times per minute. Note blowing should be pinched closed patients nostrils, parallel counterparts sealed. Rescuers blown gas is 18% oxygen (the atmosphere containing 21% oxygen), as long as the inflatable properly, patients can obtain sufficient oxygen.
               
    C. external cardiac massage

    Artificial methods that make the heart beat, the flow of blood to the lungs of oxygen to the brain and other vital organs. The rescuers used a palm root is placed under the patient’s sternum 1/3, another palm in one hand and the back of the overlap in root, then the two arms Bengzhi Press down on the power of the waist, and a depth of 3.5 to 4.5 cm. The frequency of 80 to 100 times per minute.
               
    These are usually called CPR. If a single operation by 15:2, alternating 15 external cardiac massage and artificial respiration;
                
    If a double operation by the ratio of 5:1, ie alternating external cardiac massage and artificial respiration.
             
    Cardiopulmonary resuscitation can not be halted, has been to adhere to the ambulance to arrive, timely first aid “baton" passed to the attendant doctors, is expected to greatly improve the survival rate of sudden death.
