Signs of life and death

If life - one of the highest forms of movement and the organization of matter, then death - irreversible cessation of vital activity, the inevitable natural end to the existence of any living creature. But death, especially in our time, quite often the result of murder, suicide, injuries incompatible with life. Having the appropriate skills to provide urgent and emergency care, we are unable to return "from the other world" of many people.


There are two main stages of death - the so-called near-death experience and following a biological or real death. Clinical death - a reversible stage of dying, flowing for several minutes after cessation of circulatory and respiratory systems. Reversibility it mainly depends on the degree of hypoxia (hypoxia - oxygen starvation) changes in cells of the central nervous system, and above all the important parts of the brain. Length of stay human in a state of clinical death at normal ambient conditions is less than 8 minutes in the same low temperature, it increases.

Onset of clinical death precedes predagonalnoe state (a gradual reduction in blood pressure, respiratory depression, consciousness and the brain's electrical activity, tachycardia, bradycardia, and replaced by others). Our task - to help ensure that clinical death is not transferred to the biological, when all the vital processes of irreversibly terminated.

Since the victim was alive or dead, sick? This issue is very important in severe injuries, drowning, frostbite, when a person shows no signs of life. Having found at least minimal signs of life, it is necessary to proceed immediately to revive the victim.

Clinical death occurs, for example, a fall from a tree, cliff, with traffic accidents, falls, drowning, when a man plunges into deep unconsciousness. More often it is observed in the skull injuries, and tightness in the chest or abdomen, with severe cardiovascular disease (myocardial infarction, komah different origin). The victim lies motionless, sometimes without giving any signs of life. Let's try to distinguish life from death.

Must first determine whether there is a heartbeat - with your hand or ear. Puts his ear below the nipple, and if tapped, even rare and deaf heart sounds, this is the first sign that a person is alive. You should check the pulse of, especially on the neck, where the largest artery - the carotid, or on the inside of the forearm.

You must verify if the victim is breathing. This is indicated by the movement of the chest, wetting the mirror attached to the nose of the victim, or the movement of fleece, presentation to the nostrils.

Pay attention to the state of the eyes. If the highlight of their lantern, pupils suzyatsya and the same happens when the victim opened his eyes to obscure the hand and then quickly withdraw his hand away. But remember: if a deep unconscious reaction to light might not be.

If at least one of the above symptoms you will notice a positive result, meaning that immediate assistance can still be successful. In this case should take active steps to revitalize what we say in detail in the description of the nature of an injury or illness.

If our efforts to revive the man will be in vain and we will see that he is dead, do not waste your time - better to go to the next victim.

What signs indicate that the person is dead? Death occurs when the work stoppage of the heart and respiratory arrest. The body lacks oxygen, the lack of which causes death of brain cells. That is why during resuscitation main focus should be on the activity of the heart and lungs in order to make them work, meaning that they provide the brain with oxygen. Only this can bring a person from a state of clinical death.

Setting, the victim was alive or dead, come from the manifestations of clinical and biological death, the so-called questionable and obvious signs of cadaver.

Questionable signs of death. The victim is not breathing, heartbeat not detected, there is no reaction to the needle stick, the pupils do not react to bright light. While there is no certainty that the victim died, we are obliged to undertake all efforts to revive him.

Obvious signs of death. These are signs of rigor mortis. One of the first and main features - clouding of the cornea and its drying. While squeezing his eyes from the sides with your fingers pupil narrows and resembles cat's eye.

Rigor mortis starts to head in 2-4 hours after death. Cooling of the body occurs gradually: corpse appear bluish spots, arising from the flowing blood in the appropriate parts of the body. The corpse, lying on his back, corpse spots observed on the lower back, buttocks and shoulder. At the position on the abdomen spots appear on the face, chest and on the relevant parts of the limbs.

If you see this, you have no reason to do anything, you only need to notify the appropriate authorities.
