Since autumn, the temperature difference between day and night gradually increases, cardiovascular patients should pay attention to the temperature changes. Recently, suffering from coronary heart disease, Master Li got up in the morning for a morning walk and had a sudden heart attack, although people around him immediately called 120, but when the paramedics arrived the time was still too late. Cardiac arrest is extremely dangerous, the heart stopped, all circulation also stopped, breathing also stopped, the brain will be lack of oxygen, ischemia, generally within a few minutes, the patient did not get the right aid, it will produce irreversible damage to the brain, about 10 minutes may lead to brain death, or even life directly end. So what should we do when we encounter a patient with an acute heart attack or suspected acute heart attack before the arrival of an emergency physician? Let the patient rest quietly Avoid stimulation If the patient has chest pain while exercising, then let him stop exercising immediately. If the patient is agitated, then make sure to do your best to bring him back to calm. Choose a comfortable position for the patient What is a comfortable position? Depending on the patient’s feeling, he can lie down or sit down. 1, if the patient has respiratory distress, it may be the occurrence of acute left heart failure, the patient should be helped to take a sitting position with both lower limbs down, the position should be as comfortable as possible, this can reduce the compression of the abdominal organs on the lungs, so that the pulmonary ventilation will not be further reduced, more importantly, due to the effect of gravity, it can reduce the amount of blood flow back to the heart, thus reducing the heart load. 2, if the patient’s blood pressure has dropped, or even shock, then he must be made to lie flat, or even remove the pillow, and pay attention to keep warm, and also prevent asphyxia caused by vomiting. 3, if acute left heart failure and shock occur at the same time, it can be too difficult to do. Lying flat will aggravate the respiratory distress; sitting up will make the cerebral blood supply more reduced, and even loss of consciousness. Only let the patient take a semi-recumbent position, and adjust the angle according to the situation. Give the patient oxygen, medicine If you have oxygen bottles at home, quickly let the patient inhale oxygen, 3 ~ 5 liters per minute, with the dual role of rescue and psychological comfort, can increase the oxygen supply to the heart muscle to reduce symptoms. Without oxygen, look for medicine directly. Here to remind everyone, especially families with elderly people, always have some emergency drugs at home, such as nitroglycerin, aspirin, etc., can help in critical moments. Call 120 Be ready for CPR If someone in the family has an acute heart attack, in addition to chewing aspirin and immediately calling the emergency number, you should always be ready for CPR. Here’s a reminder: when you encounter a patient with an acute heart attack, people around you (such as family members) should not move the patient at will! This is because moving a patient with a heart attack will increase the oxygen consumption of the heart muscle, which adds an extra burden to the heart and is likely to continue to expand the area of the heart attack, aggravate the condition and promote sudden death.
