In what stages can the process of human death be divided?

The process of human death is usually divided into three phases:

1. Near-death period. Also known as the struggle period, refers to the final stage of human struggle before death. Generally have a bitter face, sometimes snoring, increased blood pressure, fuzzy consciousness or disappearance, the body's various reflexes weakened, slow or disappear, blood pressure decreased, pulse and respiration weakened or periodic breathing, the duration of the period of time varies, can be from a few seconds to a few hours or longer.

2. Clinical death period. It is a short stage before biological death. The performance of respiration and heartbeat stop, the body's various reflexes completely disappeared, from the appearance of the human body's vital activities have stopped, but the weak metabolic process within the organization is still going on, life may be resuscitated, this period is usually 5-6 minutes.

3. Biological death. Body tissues and cells of the vital activities of the cessation of life and trapped in a state that can not be restored to go through a process, first of all, the cerebral cortex, and then the entire central nervous system can not return to the changes occurring in the body of various organs and tissues function of the disintegration of heartbeat, respiratory arrest. Artificial methods of resuscitation can not be successful, brain hypoxia for more than 5-6 minutes, brain cell necrosis, the central nervous system function permanently stopped.

The causes of human death are categorized

1. The root cause of death is the initial cause of death, such as the primary cause of death, natural disease or violence. Natural diseases or violent factors. In cases of death from natural diseases, the main cause of death is consistent with the main disease, such as death from advanced malignant tumors, death from coronary heart disease myocardial infarction. In violent deaths such as mechanical injury, mechanical asphyxiation and other causes of death.

2, the direct cause of death. If the root cause of death does not go through the intermediate links directly caused by death, this cause of death is both the root cause of death, but also the direct cause of death, is also the only cause of death. The root cause of death did not immediately cause death, but because of its secondary consequences or complications, the latter for the direct cause of death. Common direct causes of death in forensic medicine are infection, hemorrhage, embolism, poisoning, and systemic failure.

3, auxiliary cause of death, the main cause of death outside the natural disease or injury, they will not be fatal, but in the process of death play a supporting role. For example, patients with severe fatty liver died of alcoholism, alcoholism is the main cause of death, and fatty liver for the auxiliary cause of death. A patient with a huge aneurysm died after being punched and the aneurysm ruptured, the aneurysm was the main cause of death and the punch was an auxiliary cause of death.

4, causative factors, triggering the body's original potential disease deterioration and cause death factors, including a variety of mental and emotional factors, overwork, smoking, trauma, large amounts of alcohol, sexual intercourse, overfeeding, starvation, cold and so on. These factors are generally not fatal to healthy people, but to some vital organs with potential lesions, but can induce disease deterioration and cause death.

5, joint cause of death, two or more than two difficult to distinguish between the primary and secondary causes of death in the same case together to cause death and **** the same composition. Including: disease and disease joint death, disease and violence joint death, violence and violence joint death.
