Step 1

Death can be clinical, social, or biological. Clinical death is reversible and can be overcome with the help of specialists. Social death occurs when mental functions fade away and the brain partially dies. Such patients are often called vegetables, the state of social death is irreversible. And biological death has some signs by which it is possible to determine whether a person needs resuscitation or not.

Step 2

The first step is to determine the presence or absence of a heartbeat. Check the pulse in the neck or put your ear to the heart area, listen. If even rare or dull tones are heard, then you should immediately provide first aid and call an ambulance. Make sure the victim is breathing. Take a mirror and bring it to the person's nose, if it fogs up, then the victim is alive. You can bring a cotton swab to your nose; by the movement of the villi, you can determine the presence of breathing.

Step 3

Raise the person's eyelids and shine a flashlight into their eyes. The pupils of a living person will shrink; in a dead person, their appearance does not change. Please note that with a deep loss of consciousness, the pupils may not react to light. Among the early signs of biological death, it is also worth noting: dilated pupils (but only if the death did not come from drugs); when the eyeball is squeezed, a cat's pupil is formed, and the eye loses its original shape; drying out and clouding of the cornea of ​​the eye in open areas occurs.

Step 4

The body temperature of a dead person drops. Rigor mortis begins from the head and gradually moves to the extremities. After a while, cadaveric relaxation occurs, in exactly the same sequence. Death can also be determined by the presence of cadaveric spots, which can be pink or dark blue, most often occur in the lower parts of the body. Under the influence of gravitational forces, it is there that blood and body fluids flow down.
