What are the signals a few days before people are going to die suddenly?

Sudden death is a sudden death, and the patient has no expected symptoms. Sudden death is common in patients with organic heart disease, such as coronary heart disease, hypertrophic cardiomyopathy and other diseases.

Patients who stay up late for a long time, overwork, emotional excitement and strenuous exercise will suddenly have some manifestations, such as dizziness, headache, chills in limbs, difficulty breathing, sudden acceleration of heartbeat, angina pectoris, etc., which is easy to induce sudden death. Be careful not to stay up late, keep a good attitude and eat reasonably and healthily. And regular physical examination, active treatment of basic diseases, to prevent sudden death.

Sudden death is the most serious disease of mankind. Different documents

How long does it take from onset to death to be considered as sudden death? At present, there is no recognized unified standard for the specific quantitative time. Some people think that the time from onset to death is within 1 hour, 6 hours, 12 hours and 24 hours respectively, and some people think that the death within 48 hours is also included. The World Health Organization believes that the time is within 6 hours, but this is only a family statement. At present, it is recognized that most of the deaths within 1 hour are sudden cardiac death.

The connotation of sudden death can be condensed into six words, that is, the patient died suddenly due to illness. These six words accurately and concisely summarize the three elements of the connotation of sudden death:

Element 1: The patient has died. Therefore, patients who are not dead cannot be identified as sudden death. Sudden death is a final diagnosis and a final conclusion. Therefore, sudden death is a disease that can only be prevented and cannot be treated. Any situation that can be treated or even cured or successfully revived cannot be called sudden death.

Element 2: The patient died of natural causes, that is, because of his own disease, and the death was caused by internal factors of the patient's body. Rather than the external factors of the patient's body, not the unnatural reasons such as drowning, electric shock, hanging, poisoning, low temperature, high temperature, violence, blood loss, trauma, anesthesia, surgery, etc.

Element 3: Sudden death occurs suddenly, and its occurrence time is unpredictable, that is to say, the patient does not show signs of imminent death, so no one thinks that the patient is about to die, but death happened. Therefore, any predictable death is not sudden death. The most common clinical cases are patients with terminal diseases, such as advanced cancer and various diseases. The patients' lives are gradually coming to an end, and the clinical manifestations are obvious. Once the patients leave, this kind of death is not sudden death.

How do you feel when people die suddenly?

Sudden death refers to a natural and unexpected sudden death. According to the World Health Organization, death within 6 hours after onset is regarded as sudden death. All kinds of heart diseases can lead to sudden death, and more than half of sudden death of heart diseases is caused by coronary heart disease.

Experts believe that the sudden death of a person shows that his illness has reached a certain level. If you only encounter great joys and sorrows in your life, or encounter bad weather, it is not enough to endanger your life without a serious pathological basis.

There are roughly the following types of sudden death: 1. Sudden cardiac death, the most common sudden death, occurs within 1 hour after onset, and some even lasts only a few minutes, which is mainly related to severe arrhythmia. Coronary heart disease is the most common. Some people can have no angina pectoris and other heart symptoms, coronary heart disease is hidden, and sudden death is the earliest manifestation. This is the case when many so-called "healthy people" suddenly die. Hypertension involving the heart and causing left ventricular hypertrophy is also prone to sudden death.

2。 Sudden death due to stroke generally, the time from onset to death can reach several hours to 1 day. It is more common in hemorrhagic stroke with large amount of hemostasis and rapid bleeding, which involves important life center parts. It can also be seen in ischemic stroke involving important parts in Fan Guo. Patients with coronary heart disease and atrial fibrillation, accompanied by left atrial thrombosis, once the thrombus falls off into the cerebral circulation, causing multiple cerebral infarction, sudden death will occur. Those with a history of stroke and encephalomalacia are also prone to sudden death after another stroke.

3。 Patients with pulmonary sudden death, such as chronic bronchitis, emphysema and bronchial asthma, may die suddenly because of severe hypoxemia at night: respiratory acidosis. Patients with chronic bronchitis and emphysema, such as excessive use of antiasthmatic aerosol, may cause bronchospasm and contraction, asphyxia and hypoxia, leading to sudden death. The elderly who have been bedridden for a long time can't cough hard to expel phlegm because of their weakness, which can cause sputum embolism to block the airway, which is even worse in the case of secondary lung infection, thus leading to sudden pulmonary death.

4。 The elderly with sudden death of choking food have poor chewing function, insensitive swallowing reflex and slower reaction after drinking, so "choking food" often occurs when eating and drinking. Large food lumps can block the trachea and cause suffocation and death. This kind of death often happens suddenly, and the patient can't speak. He often points his finger at his throat, then his face turns purple and his eyes turn up. Sudden dumping

To prevent sudden death and pay attention to health, we should conduct a comprehensive health examination every year to observe the changes of the original diseases and the occurrence of new diseases. We should actively treat these congenital and acquired diseases and avoid emotional excitement and overwork. When there are signs of discomfort or symptoms, you should go to the hospital for examination and treatment as soon as possible.
