What does a person experience when he dies? When does he realize that his consciousness is leaving him? Will something unexpected happen the moment our life comes to an end? These questions have tormented philosophers and scientists for centuries, but the topic of death continues to excite every person to this day, according to NewScientist.com.

Death comes in different forms, but one way or another, it is usually an acute lack of oxygen in the brain. Whether people die as a result of a heart attack, drowning or suffocation, it is ultimately due to a severe lack of oxygen to the brain. If the flow of freshly oxygenated blood to the head is stopped through any mechanism, the person will lose consciousness in about 10 seconds. Death will come in a few minutes. Exactly how depends on the circumstances.

1. Drowning
How quickly people drown is determined by several factors, including the ability to swim and the temperature of the water. In the UK, where the water is consistently cold, 55 percent of drownings in open water occur within 3 meters of the shore. Two-thirds of the victims are good swimmers. But a person can get into trouble in seconds, says Mike Tipton, a physiologist and expert at the University of Portsmouth in England.

As a rule, when the victim realizes that he will soon disappear under the water, panic and floundering on the surface begin. Struggling to breathe, they can't call for help. This stage lasts from 20 to 60 seconds.
When victims eventually sink, they do not inhale for as long as possible, usually 30 to 90 seconds. After this, a certain amount of water is inhaled, the person coughs and inhales more. Water in the lungs blocks gas exchange in thin tissues, a sudden involuntary contraction of the muscles of the larynx occurs - a reflex called laryngospasm. There is a feeling of bursting and burning in the chest as the water passes through the respiratory tract. Then a feeling of calm sets in, indicating the beginning of a loss of consciousness from lack of oxygen, which, ultimately, will lead to cardiac arrest and brain death.

2. Heart attack
Hollywood heart attack - a sudden pain in the heart and an immediate fall, of course, happens in a few cases. But a typical myocardial infarction develops slowly, and begins with moderate discomfort.

The most common symptom is chest pain, which may be prolonged or come and go. This is how the struggle of the heart muscle for life and its death from oxygen deprivation is manifested. The pain may radiate to the jaw, throat, back, abdomen, and arms. Other signs are shortness of breath, nausea, and cold sweats.

Most victims are in no hurry to seek help, waiting an average of 2 to 6 hours. Women are more difficult, as they are more likely to experience symptoms such as shortness of breath, radiating pain or nausea to the jaw, and do not respond to them. Delay can cost lives. Most people who die of heart attacks simply don't make it to the hospital. Often the actual cause of death is cardiac arrhythmia.

Approximately ten seconds after the heart muscle stops, the person loses consciousness, and a minute later he is dead. In hospitals, a defibrillator is used to make the heart beat, clear the arteries, and inject drugs that bring them back to life.

3. Deadly bleeding
How soon death from bleeding occurs depends on the wound, says John Kortbeek at the University of Calgary in Alberta, Canada. People can die from blood loss within seconds if the aorta is torn. It is the main blood vessel leading away from the heart. Causes include a serious fall or a car accident.

Death can occur in a few hours if another artery or vein is damaged. In this case, a person would go through several stages. The average adult has 5 liters of blood. The loss of one and a half liters causes a feeling of weakness, thirst and anxiety and shortness of breath, and two - dizziness, confusion, a person falls into an unconscious state.

4. Death by fire
Hot smoke and fire scorch eyebrows and hair and burn the throat and airways, making it impossible to breathe. Burns cause severe pain through stimulation of the pain nerves in the skin.

When the area of ​​the burn increases, the sensitivity decreases somewhat, but not completely. Third-degree burns do not damage as much as second-degree wounds because the superficial nerves are destroyed. Some victims with severe burns reported not feeling pain while they were still in danger or engaged in rescuing others. Once the adrenaline and shock gradually wear off, pain quickly sets in.

Most of the people who die in fires actually die from poisonous carbon monoxide poisoning and lack of oxygen. Some people just don't wake up.

The rate of onset of headache and drowsiness and unconsciousness depends on the size of the fire and the concentration of carbon monoxide in the air.

5. Decapitation
Execution is one of the quickest and least painful ways to die if the executioner is skilled, his blade is sharp, and the condemned man sits still.

The most advanced decapitation technology is the guillotine. Officially adopted by the French government in 1792, it was recognized as more humane than other methods of deprivation of life.

Maybe it's really fast. But consciousness is not lost immediately after the spinal cord is severed. A study in rats in 1991 showed that the brain was kept alive for an additional 2.7 seconds by consuming oxygen from the blood in the head; the equivalent number for humans is approximately 7 seconds. If a person falls under the guillotine unsuccessfully, the time of pain sensation can be increased. In 1541 an inexperienced man made a gash in the shoulder rather than in the neck of Margaret Paul, Countess of Salisbury. According to some reports, she jumped from the place of execution and was pursued by the executioner, who struck her 11 times before she died.

6. Death by electric shock
The most common cause of death from electric shock is an arrhythmia leading to cardiac arrest. Unconsciousness usually follows after 10 seconds, says Richard Trohman, a cardiologist at Onslaught University in Chicago. A study of electrocution deaths in Montreal, Canada showed that 92 percent died of arrhythmias.

If the voltage is high, then unconsciousness occurs almost immediately. The electric chair was supposed to cause instant loss of consciousness and painless death due to the passage of current through the brain and heart.
Whether this actually happens is debatable. John Wickswo, a biophysicist at the University of Nashville, Tennessee, argues that the thick, insulating bones of the skull would have prevented enough current from flowing through the brain, and prisoners could die from brain heat, or from suffocation due to paralysis of the respiratory muscles.

7. Fall from a height
This is one of the fastest ways to die: the top speed is approximately 200 kilometers per hour, achieved when falling from a height of 145 meters and above. A study of fatal falls in Hamburg, Germany found that 75 percent of the victims died within the first seconds or minutes of landing.
The causes of death depend on the place of landing and the position of the person. People are unlikely to reach the hospital alive if they fall upside down. In 1981, they analyzed 100 deadly jumps from the Golden Gate Bridge in San Francisco. It has a height of 75 meters, the speed when colliding with water is 120 kilometers per hour. These are the two main causes of instant death. As a result of the fall - a massive contusion of the lung, rupture of the heart or damage to the main blood vessels and lungs by broken ribs. Landing on your feet significantly reduces injuries and can save lives.

8. Hanging
The method of suicide and the old-fashioned method of execution is death by strangulation; the rope puts pressure on the trachea and arteries leading to the brain. Unconsciousness may be observed within 10 seconds, but it will take longer if the loop is not positioned correctly. Witnesses to public hangings often reported victims "dancing" in pain in the noose for minutes! In some cases - after 15 minutes.

In England, in 1868, the "long fall" method was adopted, involving a longer rope. During the hanging, the victim reached a speed that broke her neck.

9 Lethal Injection
Lethal injection was developed in Oklahoma State in 1977 as a humane alternative to the electric chair. The state medical auditor and the chairman of anesthesiology agreed on the introduction of three drugs almost immediately. First, the anesthetic thiopental is administered to avoid any feeling of pain, then the paralytic agent pancuronium is administered to stop breathing. Finally, potassium chloride stops the heart almost immediately.

Each drug is supposed to be administered at a lethal dose in excess to ensure a quick and humane death. However, witnesses reported convulsions and an attempt by the convict to sit during the procedure, that is, the introduction of drugs does not always give the desired result.

10. Explosive decompression
Death due to exposure to vacuum occurs when the vestibule is depressurized or the suit ruptures.

When the external air pressure is suddenly reduced, the air in the lungs expands, tearing the fragile tissues involved in gas exchange. The situation is aggravated if the victim forgets to exhale before decompression or tries to hold his breath. Oxygen begins to leave the blood and lungs.

Experiments on dogs in the 1950s showed that 30 to 40 seconds after the pressure was released, their bodies began to swell, although the skin prevented them from "bursting". First, the heart rate increases, then sharply decreases. Bubbles of water vapor form in the blood and travel through the entire circulatory system, obstructing the flow of blood. After a minute, the blood ceases to effectively participate in gas exchange.

The survivors of decompression accidents are mostly pilots whose planes have depressurized. They reported sharp chest pains and an inability to breathe. After about 15 seconds, they lost consciousness.

The life on Earth of each individual is only a segment of the path in the material incarnation, intended for the evolutionary development of the spiritual level. Where does the deceased end up, how does the soul leave the body after death, and what does a person feel when they pass into another reality? These are some of the exciting and most discussed topics throughout the existence of mankind. Orthodoxy and other religions testify to the afterlife in different ways. In addition to the opinions of representatives of various faiths, there are also testimonies of eyewitnesses who survived the state of clinical death.

What happens to a person when he dies

Death is an irreversible biological process in which the vital activity of the human body ceases. At the stage of dying of the physical shell, all metabolic processes of the brain, heartbeat and respiration stop. Approximately at this moment, the thin astral body, called the soul, leaves the obsolete human shell.

Where does the soul go after death?

How the soul leaves the body after biological death and where it rushes to is a question that interests many people, especially the elderly. Death is the end of being in the material world, but for an immortal spiritual entity, this process is only a change of reality, as Orthodoxy believes. There is a lot of discussion about where the soul of a person goes after death.

Representatives of the Abrahamic religions talk about "heaven" and "hell", into which souls end up forever, according to their earthly deeds. The Slavs, whose religion is called Orthodoxy because they glorify "Right", hold beliefs about the possibility of the rebirth of the soul. The followers of the Buddha also preach the theory of reincarnation. It can only be unequivocally stated that, leaving the material shell, the astral body continues to "live", but in a different dimension.

Where is the soul of the deceased up to 40 days

Our ancestors believed, and the living Slavs to this day believe that when the soul leaves the body after death, it stays for 40 days where it lived in earthly incarnation. The deceased is attracted to places and people with whom he was associated during his lifetime. The spiritual substance that has left the physical body, for the entire forty-day period, “says goodbye” to relatives and home. When the fortieth day comes, it is customary for the Slavs to arrange the farewell of the soul to the “other world”.

Third day after death

For many centuries there has been a tradition to bury the deceased three days after the death of the physical body. There is an opinion that only at the end of the three-day period does the soul separate from the body, all vital energies are completely cut off. After a three-day period, the spiritual component of a person, accompanied by an angel, goes to another world, where her fate will be determined.

On day 9

There are several versions of what the soul does after the death of the physical body on the ninth day. According to the religious figures of the Old Testament cult, the spiritual substance, after a nine-day period after the Dormition, goes through ordeals. Some sources adhere to the theory that on the ninth day the body of the deceased leaves the "flesh" (subconscious). This action takes place after the “spirit” (superconsciousness) and “soul” (consciousness) left the deceased.

What does a person feel after death?

The circumstances of death can be completely different: natural death due to old age, violent death or due to illness. After the soul leaves the body after death, according to eyewitness accounts of coma survivors, the etheric double has to go through certain stages. People who have returned from the "other world" often describe similar visions and sensations.

After a person dies, he does not immediately enter the afterlife. Some souls, having lost their physical shell, at first do not realize what is happening. With special vision, the spiritual entity “sees” its immobilized body and only then understands that life in the material world has ended. After an emotional shock, resigned to his fate, the spiritual substance begins to explore a new space.

Many at the moment of the change of reality, called death, are surprised that they remain in the individual consciousness, to which they are accustomed during earthly life. Surviving witnesses of the afterlife claim that the life of the soul after the death of the body is filled with bliss, so if you have to return to the physical body, this is done reluctantly. However, not everyone feels peace and tranquility on the other side of reality. Some, returning from the "other world", talk about the feeling of a rapid fall, after which they found themselves in a place filled with fear and suffering.

Peace and tranquility

Different eyewitnesses report with some differences, but more than 60% of the resuscitated testify to a meeting with an amazing source that radiates incredible light and perfect bliss. To some this cosmic personality appears to be the Creator, to others as Jesus Christ, and to others as an angel. What distinguishes this unusually bright creature, consisting of pure light, is that in its presence the human soul feels an all-encompassing love and absolute understanding.

Sounds

At the moment when a person dies, he can hear an unpleasant hum, buzzing, loud ringing, noise as if from the wind, crackling and other sound manifestations. Sounds are sometimes accompanied by movement at great speed through the tunnel, after which the soul enters another space. A strange sound does not always accompany a person on his deathbed, sometimes you can hear the voices of deceased relatives or the incomprehensible "speech" of angels.

What happens to a person at the time of death? What are the sensations, reactions of the body? in the last moments of life?

1. Drowning

As soon as the drowning victim realizes that the moment is near when she will hide under water, panic immediately begins. A person is floundering on the surface, trying to breathe and cannot call for help at this time. This step takes 20-60 seconds.
After immersion, the victim tries to hold his breath for the maximum period (for 30-90 s). In the end, a small amount of water is first breathed in, as a result of coughing and drawing in a larger portion of the liquid. In the lungs, water does not allow gas exchange to occur, the muscles of the larynx are sharply reduced. This reflex is called laryngospasm.
During the passage of water through the respiratory tract, there is a burning sensation and tearing in the chest. Then calmness comes, loss of consciousness from lack of oxygen. Further cardiac arrest and death.
Although death can come from simply.

2. Heart attack

The first symptom is chest pain. It can take various forms - be long and constant, be short periodic. All these are manifestations of the struggle of the heart muscle for life, as well as its dying from a lack of oxygen. The pain is given to the arm, chin, abdomen, throat, back. Shortness of breath, cold sweat, nausea may occur.
People usually ignore these symptoms, do not seek help, wait 2-6 hours. This is especially true for women - more patient and accustomed to pain. But in this case, you can not hesitate! Usually the cause of death in such attacks is arrhythmia.
After cardiac arrest, loss of consciousness occurs within 10 seconds, and death occurs a minute later. If this happens in a hospital, then doctors have a chance to start the heart with a defibrillator, administer drugs and bring the patient back to life.

3. Deadly bleeding

The time of death from blood loss is highly dependent on the amount of blood and the site of bleeding. If we are talking about a rupture of the aorta, the main blood vessel, then the count goes to seconds. Typically, the cause of its breaks are strong blows as a result of falls or car accidents.
If other veins or arteries are damaged, death can occur within a few hours. In this case, a person goes through different stages. An adult has an average of about 5 liters of blood. After the loss of 1.5 of them comes weakness, thirst, shortness of breath and anxiety. After 2x - there will be confusion, dizziness, loss of consciousness.

4. Death by fire

In a fire, the hairline, throat and respiratory tract are the first to suffer from fire and hot smoke. Throat burns make it impossible to breathe, skin burns excite nerve endings and cause burning pain.
As the burns become deeper, the pain subsides. This is due to the fact that the nerve endings in the skin are destroyed - this layer simply burns out. Sometimes people just don't feel the damage when they're stressed. But then, when the level of adrenaline normalizes, the pain returns.
Most of those killed in a fire do not die from fire, but from carbon monoxide poisoning and lack of oxygen, often without even waking up.

5. Falling from height

One of the most effective methods of suicide. When falling from more than 145 meters, the speed reaches 200 km / h. An analysis of such cases only in Hamburg gave 75% of the dead in the first seconds or minutes after landing.
Causes of death can vary greatly from body position and landing site. Highest chance of instant death when jumping upside down.
So research was done on 100 lethal jumps from the Golden Gate Bridge in San Francisco. Its height is 75 m, the body reaches a speed of 120 km/h by the moment of collision with water. When falling, a person gets a heart rupture, a lung contusion, damage to the main vessels by fragments of the ribs. If the landing occurred on your feet, then there are much fewer injuries and more chances to survive.

The light at the end of the tunnel is a popular representation of how we feel when we enter another world. But as BBC Future correspondent Rachel Nieuwer says, the experiences of near-death survivors are much more varied.

The experience of people who have survived clinical death refutes the popular notion of our feelings on the verge of life and death.

In 2011, a 57-year-old social worker from England - let's call him Mr A - was taken to Southampton Central Hospital after he collapsed on the job. While doctors were trying to insert a catheter into the patient, his heart stopped. Without access to oxygen, the brain instantly ceased to function. Mr A. has died.

Despite this, he remembers what happened next. Medics took an automated external defibrillator (AED), a machine that activates the heart with an electric shock. Mr. A. heard a mechanical voice repeat twice: "Discharge." Between these two commands, he opened his eyes and saw a strange woman in the corner under the ceiling, who beckoned him with her hand.

Image copyright Thinkstock Image caption The light at the end of the tunnel is just one of many scenarios for the feeling of death.

“She seemed to know me, I felt trust in her, I thought she was here for a reason, but I didn’t know for what,” Mr. A later recalled. “The next second I was upstairs, looking down at himself, a nurse, and some bald man."

Researchers believe that it is quite possible to collect objective scientific data on potentially last moments of life. Over the course of four years, they analyzed more than 2,000 patients who survived cardiac arrest, that is, official clinical death.

Image copyright Thinkstock Image caption It felt like I was being pulled deep underwater

Of this group of patients, doctors were able to bring 16% back to life. Dr. Parnia and his colleagues interviewed a third of these patients - 101 people. “Our goal is to understand first of all what people feel at the time of death,” says Dr. Parnia. “And then to prove that what patients say they see and hear at the time of death is indeed an awareness of reality.”

Seven Shades of Death

Mr. A is not the only patient who had memories of his death. Nearly 50% of study participants could remember something. But unlike Mr. A and another woman, whose account of being out of her own body cannot be objectively proven, the experiences of the other patients did not seem to be tied to the actual events that took place at the time of their death.

Their stories were more like dreams or hallucinations, which Dr. Parnia and his colleagues divided into seven main scenarios. "Most of them didn't fit with what used to be called 'near-death' experiences," says Parnia. "It appears that the psychological experience of death is much broader than we imagined in the past."

These seven scenarios include:

• Fear
• Images of animals or plants
• Bright light
• Violence and persecution
• Deja vu or the feeling of "already seen"
• The faces of family members
• Memories of events after cardiac arrest

Mental experiences of patients range from eerie to blissful. Some patients report feelings of overwhelming terror or persecution. For example, like this. “I had to go through a burning ceremony,” recalls one participant in the study. “There were four people with me, and if one of them lied, he had to die ... I saw people in coffins who were buried in an upright position.”

Another person recalls being "dragged deep underwater" and another patient says that "I was told I was going to die and the quickest way to do that was to say the last little word I don't remember."

However, other respondents report rather opposite feelings. 22% recall "feeling of peace and tranquility." Some saw living creatures: "Everything and everything around, in plants, but not flowers" or "lions and tigers." Others bathed in "bright light" or reunited with family. Some had a strong sense of déjà vu: "I felt like I knew exactly what people were going to do and they really did." Heightened senses, a distorted sense of time, and a feeling of separation from one's own body are common memories of near-death patients.

Image copyright Thinkstock Image caption Some patients felt that they were separated from their own body.

While "certainly people felt something at the time of death," Prof. Parnia says, how they would interpret those experiences depended entirely on their life experiences and beliefs. Hindus may have said they saw Krishna, while a Midwesterner in the United States claimed to have seen God. “If a person who is brought up in Western society is told that when you die, you will see Jesus Christ, and he will be full of love and compassion, then he will certainly see him,” says the professor. “She will return and say:“ Father, you are right, I really saw Jesus!" But how can any of us recognize Jesus or another God? You do not know what God is. I do not know what he is. Except for the images of a man with a white beard, although everyone understands that it's a fabulous show."

“All this talk about the soul, heaven and hell - I have no idea what they mean. There are probably thousands of interpretations, depending on where you were born and how you were raised,” the scientist says. “It is important to move these memories from the realm of religion into reality."

Common cases

So far, the team of scientists has not established what will determine the ability of patients to remember their feelings at the time of death. Explanations are also lacking as to why some people experience scary scenarios while others talk about euphoria. Dr. Parnia also notes that apparently more people have near-death memories than the statistics suggest. Most people lose these memories due to massive cerebral edema caused by cardiac arrest or heavy sedatives given to them in intensive care.

Even if people cannot remember their thoughts and feelings at the time of death, this experience will undoubtedly affect them on a subconscious level. The scientist suggests that this explains the very opposite reaction of patients who came back to life after cardiac arrest. Some no longer fear death at all and begin to relate to life more altruistically, others develop post-traumatic stress disorder.

Professor Parnia and his colleagues are planning further research to find answers to these questions. They also hope that their work will help shed new light on ideas about death and free it from stereotypes associated with religion or skepticism.

Death may well be the object of scientific study. "Any person with an objective mindset will agree that research should continue," says the scientist. "We have the capabilities and technologies. Right now is the time to do it."

It is not customary to talk about death out loud in our time. This is a very touchy subject and not for the faint of heart. But there are times when knowledge is very useful, especially if there is an elderly person with cancer or a bedridden person at home. After all, it helps to mentally prepare for the inevitable end and notice the changes taking place in time. Let's discuss the signs of death of the patient together and pay attention to their key features.

Most often, signs of imminent death are classified into primary and secondary. Some develop as a consequence of others. It is logical that if a person began to sleep more, then he eats less, etc. We will consider all of them. But, cases may be different and exceptions to the rules are acceptable. As well as variants of a normal median survival rate, even with a symbiosis of terrible signs of a change in the patient's condition. This is a kind of miracle that happens at least once in a century.

Changing sleep and wake patterns

Discussing the initial signs of impending death, doctors agree that the patient has less and less time to stay awake. He is more often immersed in superficial sleep and seems to be dozing. This saves precious energy and less pain is felt. The latter fades into the background, becoming, as it were, background. Of course, the emotional side suffers greatly.

The paucity of expressing one's feelings, the isolation in oneself, the desire to be silent more than to speak, leave an imprint on relationships with others. There is no desire to ask and answer any questions, to be interested in everyday life and people around.

As a result, in advanced cases, patients become apathetic and detached. They sleep almost 20 hours a day if there is no acute pain and serious irritants. Unfortunately, such an imbalance threatens with stagnant processes, mental problems and accelerates death.

puffiness

Edema appears on the lower extremities.

Very reliable signs of death are swelling and the presence of spots on the legs and arms. We are talking about malfunctions of the kidneys and circulatory system. In the first case, with oncology, the kidneys do not have time to cope with toxins and they poison the body. At the same time, metabolic processes are disturbed, blood is redistributed unevenly in the vessels, forming areas with spots. It is not for nothing that they say that if such marks appear, then we are talking about complete dysfunction of the limbs.

Hearing, vision, perception problems

The first signs of death are a change in hearing, vision and a normal sense of what is happening around. Such changes can be against the background of severe pain, oncological lesions, stagnation of blood or tissue death. Often, before death, a phenomenon with pupils can be observed. The eye pressure drops and you can see how the pupil deforms like a cat when you press it.
Hearing is all relative. It can recover in the last days of life or even worsen, but this is already more agony.

Decreased need for food

Deterioration of appetite and sensitivity are signs of imminent death.

When a cancer patient is at home, all relatives notice signs of death. She gradually refuses food. First, the dose is reduced from a plate to a quarter of a saucer, and then the swallowing reflex gradually disappears. There is a need for nutrition through a syringe or tube. In half of the cases, a system with glucose and vitamin therapy is connected. But the effectiveness of such support is very low. The body is trying to use up its own fat stores and minimize waste. From this, the general condition of the patient worsens, drowsiness and shortness of breath appear.

Urination disorders and problems with natural needs

It is believed that problems with going to the toilet are also signs of approaching death. No matter how ridiculous it may seem, but in reality there is a completely logical chain in this. If a bowel movement is not carried out every two days or with the regularity to which a person is accustomed, then feces accumulate in the intestines. Even stones can form. As a result, toxins are absorbed from them, which seriously poison the body and reduce its performance.
Roughly the same story with urination. The kidneys are harder to work. They pass less and less fluid and as a result, urine comes out saturated. It has a high concentration of acids and even blood is noted. For relief, a catheter can be installed, but this is not a panacea against the general background of unpleasant consequences for a bedridden patient.

Problems with thermoregulation

Weakness is a sign of imminent death

Natural signs before the death of the patient are a violation of thermoregulation and agony. The extremities begin to get very cold. Especially if the patient has paralysis, then we can even talk about the progress of the disease. The circle of blood circulation is reduced. The body fights for life and tries to maintain the efficiency of the main organs, thereby depriving the limbs. They can turn pale and even become cyanotic with venous spots.

Weakness of the body

Signs of imminent death can be different for everyone, depending on the situation. But most often, we are talking about severe weakness, weight loss and general fatigue. There comes a period of self-isolation, which is aggravated by internal processes of intoxication and necrosis. The patient cannot even raise his hand or stand on a duck for natural needs. The process of urination and defecation can occur spontaneously and even unconsciously.

Clouded mind

Many see signs of impending death in the disappearance of the patient's normal reaction to the world around him. He can become aggressive, nervous, or vice versa - very passive. Memory disappears and attacks of fear on this basis may be noted. The patient does not immediately understand what is happening and who is nearby. In the brain, the areas responsible for thinking die off. And there may be obvious inadequacy.

Predagony

This is a protective reaction of all vital systems in the body. Often, it is expressed in the onset of stupor or coma. The main role is played by the regression of the nervous system, which causes in the future:
- decreased metabolism
- insufficient ventilation of the lungs due to respiratory failures or alternating rapid breathing with a stop
- serious tissue damage

Agony

Agony is characteristic of the last minutes of a person's life

Agony is usually called a clear improvement in the patient's condition against the background of destructive processes in the body. In fact, this is the last effort in order to maintain the necessary functions for the continuation of existence. It may be noted:
- improved hearing and vision
- adjusting the rhythm of breathing
- normalization of heart contractions
- recovery of consciousness in the patient
- muscle activity by type of convulsions
- decreased sensitivity to pain
The agony can last from a few minutes to an hour. Usually, it seems to portend clinical death, when the brain is still alive, and oxygen stops flowing into the tissues.
These are typical signs of death in bedridden patients. But don't dwell too much on them. After all, there may be another side of the coin. It happens that one or two of these signs are simply a consequence of the disease, but they are quite reversible with proper care. Even a hopelessly bedridden patient may not have all these signs before death. And this is not an indicator. So it's hard to talk about commitment.
