What a person feels when he dies? When he realizes that his mind is leaving? Will there be something unexpected at a time when our lives come to completion?
As a rule, when the victim realizes that soon will disappear under water, and panic starts thrashing on the surface. Struggling to breathe, they can not call for help. This stage lasts 20 to 60 seconds.
When victims eventually sink, they do not breathe as long as possible, typically 30 to 90 seconds. After that, they inhale some water, a person coughs and breathes more. Water in the lungs blocks gas exchange in delicate tissues, there is a sudden involuntary contraction of the muscles of the larynx - a reflex called laringospazmom. There is a feeling of tearing and burning in his chest as the water passes through the airway. Then comes a sense of calm, indicating the beginning of the loss of consciousness from lack of oxygen, which ultimately lead to cardiac arrest and brain death.
2. Heart pristup
The most common symptom - pain in the chest, which can be long or appear and disappear. So the struggle of the heart muscle is shown for life and her death from oxygen deprivation. Pain can give in the jaw, neck, back, stomach and arms. Other symptoms: shortness of breath, nausea and cold sweats.
Most of the victims are in no hurry to ask for help, waiting an average of 2 to 6 hours. With women more difficult, as they are more likely to experience symptoms such as shortness of breath, pain in the jaw donating or nausea, and react to them. Procrastination can cost lives. Most people who die from heart attacks, just does not get to the hospital. Often, the actual cause of death - heart arrhythmia.
After about ten seconds after stopping the heart muscle person loses consciousness, and a minute later he was dead. Hospitals using the defibrillator make your heart beat, makes clearing the artery and injected drugs, which returns to life.
3. Lethal krovotechenie
People can bleed to death in a few seconds if the torn aorta. This is the main blood vessel leading from the heart. The reasons are a serious fall or a car accident.
Death can occur within a few hours, if the other is damaged artery or Vienna. In such a case, the person would have passed several stages. The average adult has 5 liters of blood. The loss of one and a half liters a feeling of weakness, thirst, anxiety and shortness of breath, and two - dizziness, confusion, a person falls into a state of unconsciousness.
Hot smoke and flames singe eyebrows and hair and burn the throat and airways, making it impossible to breathe. Burns cause severe pain through stimulation of the nerves of pain in the skin.
When the burn area increases, the sensitivity is somewhat reduced, but not completely. Third-degree burns do not hurt as much as second-degree wounds, as superficial nerves are destroyed. Some victims with serious burns reported that did not feel pain while they were still in danger or involved in rescue others. Once the adrenalin and shock gradually pass quickly causes pain.
Most people who die in fires actually die from carbon monoxide poisoning by toxic gases and oxygen deficiency. Someone just does not wake up.
5. Falling from vysoty
This is one of the fastest ways to die: speed limit - about 200 kilometers per hour, is achieved by a fall 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 few seconds or minutes after landing.
Causes of death depend on the landing site and the human condition. People are unlikely to reach the hospital alive, if they fall headfirst. In 1981, we analyzed the 100 deaths jumping from the Golden Gate Bridge in San Francisco. It has a height of 75 meters, the velocity of the collision with water at 120 kilometers per hour. These are two main causes instant death. As a result of the fall - a massive bruised lung, a heart attack or damage to the major blood vessels of the lungs and broken ribs. Landing on his feet considerably reduces injuries and save lives.
If the astronaut will be released into open space without a spacesuit, the first thing he feels - this expansion of air in the lungs. If he does not have time to breathe, there will be a gap of light. At the same time the body starts to come out of oxygen. Under internal pressure, the body will begin to expand, but the elasticity of the skin will not give the body burst. The blood will form bubbles of steam that will clog blood vessels, resulting in the blood will cease to participate in gas exchange. People who fall under decompression are the pilot of the plane, which for some reason depressurized, they talk about the inability to breathe and within 15 seconds lose consciousness.
7. Cutting off golovy
The most advanced machine for heading was established back in 1792 and it was called the guillotine. She was considered the most humane, since the person does not feel pain during the execution. However, this is not quite true, is the brain continues to live more about 7 seconds, powered by oxygen in the blood. Whether the person continues to experience pain in this case - is unknown, but most likely not, because at this moment the brain begins to suffer dramatically anoxia.
In this case, the noose compresses artery and the trachea, which leads to the human brain. Here the most important thing is the correct location of the loops, with its "good" position, a person loses consciousness within 10 seconds. If the loop is unsuccessful, then hung may writhe in 2 minutes, and in some cases within 15 minutes. That is why even in the distant 1868 in England began to hang the "long rope", in this case the person in the fall broke the neck, and he died quickly.
9. Lethal injections
This method replaces the electric chair as more humane. This method consists of three drugs administered immediately, first analgesic that man felt nothing, then a substance that stops the breath and at the end of the drug stops the heart almost instantly. In addition, each of the drugs administered in excessive doses. However, there were cases of people who were administered the drugs tested sudorgi.
10. Electric stul
When a voltage of 220 wills person loses consciousness, which is 10 seconds and the main cause of death is considered death from arrhythmia (a malfunction of the heart). If the voltage is high, the person loses consciousness almost immediately. The electric chair, the person loses consciousness at once, and his death is fast enough by passing electricity through the heart and brain. It is believed that this death is painless and humane, but not all agree with this. Some scientists believe that in the electric chair, the man probably died from heat the brain, as the bone of the skull greatly limits the flow of current through the brain, or death occurs from respiratory paralysis.
