Without oxygen, a person will suffocate, and will a person die after suffocation?

Oxygen is very important for each of us, and the reason why people can survive on the earth is because there is oxygen on the earth that can be used by the human body to breathe. We all know that suffocation without oxygen is divided into several stages of human suffocationIn the early days of the words may not die,But if the situation is too severe, it will lead to respiratory arrest, and then the person will also die, so let's explain it in detail.

We all know that oxygen is the gas that maintains the normal breathing of our human body, many times our body will have some breathing problems, in fact, this is very dangerous, once the person's breathing stops, then the person will also die, so for this problem, we should pay attention. In our social life, sometimes there will be suffocation, and there are many reasons for suffocation, such as the space is too small, the lack of oxygen due to lack of ventilation, which causes suffocation, or the altitude is too high, the air is thin, etc.

We all know that if there is no oxygen, you will suffocate, then you may die after suffocation, and suffocation is also divided into multiple stages, first of all, you will not die in the early stage of asphyxia, and the general signs in the early stage are that the body will feel dizzy, weak, weak and other conditions. The second is difficulty breathing.

stage, we all know that when the body is in this state, carbon dioxide in the human body.

It will increase, and the symptoms of shortness of breath will appear.

In the end, there is the stage of end-respiration, which is already a dangerous period for people at this stage.

If the body is severely deprived of oxygen, it will lead to more and more carbon dioxide content in the human body, which will lead to symptoms such as psychological irritability or nausea, so the whole person will be in a state of weakness, which will directly lead to respiratory arrest, so it will lead to death. That's it for some of the problems I've summarized about shortness of breath, let's explain them in detail.

Yes. Human breathing is the inhalation of oxygen and the exhalation of carbon dioxide. Oxygen enters the body, binds to the bloodstream, and enters the pulmonary circulation. If there is no oxygen, then the blood cannot circulate, the normal physiological activities of the person cannot be completed, and the heart cannot beat, and it dies.

First of all, you will not die in the early stage of asphyxia, and the general signs in the early stage are that the body will feel dizzy, weak, weak and weak. The second is the dyspnea stage, we all know that when the body is in this state, the carbon dioxide in the body increases, and at this time, the symptoms of shortness of breath will appear. If the body is severely deprived of oxygen, it will lead to more and more carbon dioxide content in the human body, which will lead to psychological irritability or nausea and other symptoms, so the whole person will be in a state of weakness, which will directly lead to respiratory arrest, so it will lead to death.

It is possible to go through the analysis of current medical means.

It is well known that the standard by which hospitals determine whether a person has died is the determination of the heartbeat. If there is no heartbeat, the doctor will basically tell the family that a person is no longer healthy. Just like in ancient times, people would explore the human nose and breath.

If there is no breathing or heartbeat, death is basically certain. With the development of science and technology, death is decided. The criterion for whether a person dies or not is not death of the heart or death of breathing.

For the previous human scientific and technical disability, it is now up to be determined whether a person is actually dead or not.

It is necessary to know that a person's respiratory function and heartbeat function are controlled by the brainstem. If the brain dies, it means that the person has indeed died, that is, in the process of brain death. Actually many people in the world experience a brief cardiac arrest, but after a while, they will return to their heartbeat, don't think it's a cadaveric fraud!

It's just that the body is dead, but the brain is alive, but it doesn't die until a few hours later!

After determining whether the person is dead or not based on the heartbeat, there will be a lot of grief from the family members. In this case, those who are determined to die do not know how to feel the external environment, they can also hear external voices, and they can hear the grief of family members about their death. This is called physical death, not brain death.

When the body gets out of control, the brain falls into an abyss of powerlessness. You can hear your family crying and just feel pitch black!

Therefore, after brain death is confirmed, when the family is crying, the deceased cannot hear it. With the continuous development of social science and technology, people's life expectancy is getting longer and longer, so cherish the people in front of you! Don't wait until the person who lost knows the tears and go home often!

Summary. Suffocation can lead to breathing difficulties. If there is asphyxia, it may be caused by a lack of oxygen to the brain, or it may be caused by heart disease, or it may be caused by some infection, which may be related to various diseases, so it must be sent to the hospital in time during the onset of the disease, so that the body can recover health.

Suffocation can lead to breathing difficulties. The emergence of asphyxia may be caused by a lack of oxygen in the brain, or it may be caused by heart disease, or some infection, which may be related to various diseases, so it must be sent to the hospital in time during the onset of the disease, so that the body can recover health.

After asphyxiation rescue, can not breathe spontaneously, if there is no spontaneous breathing, accompanied by blood, this situation is more serious, it is best to use a ventilator to assist the stool for breathing, must cooperate with the doctor's positive **, try to restore vital signs, family members do not need to worry about relaxation and patience, must communicate with the doctor in a timely manner to cooperate with the doctor's **, to maintain a good repentance mentality.

If you can breathe on your own, it's okay.

Yes, but you still have to be observed in the hospital for a while<><

When the oxygen content in the air is less than 6%, humans will cramp, stop breathing, and die.

Oxygen element: atomic weight is. At room temperature and pressure, oxygen is a colorless and odorless gas, which supports combustion and can supply breathing; Melting point, boiling point, gas density gram liter (oxygen in a low temperature and high pressure environment, is a light blue liquid). For every 10 litres of normal air, there are about litres of oxygen.

If the concentration of oxygen in the air is reduced to 18%, it is a safe limit for human breathing. When the oxygen concentration is reduced to 16%, it causes our breathing and pulse to speed up. When the oxygen concentration is as low as 10%, humans turn pale, vomit, and lose consciousness.

When the oxygen concentration is less than 8%, the person will fall asleep and die after 8 minutes. When the oxygen concentration is 6% left, the human will cramp, stop breathing, and die.

Because human survival requires organic matter to provide energy. Organic matter breaks down long-standing energy in the mitochondria of cells, and oxygen is required to break down organic matter. But the need for oxygen to survive is only for animals. Some microorganisms do not need oxygen to live.

The body needs energy to maintain normal metabolic activity. For example, the maintenance of the function of Na-K-ATPase on the cell membrane consumes a lot of energy in the body, and if the energy is insufficient, the activity of the enzyme will decrease, the intracellular NA will increase, and the cell will be edema and necrosis. Most of the other metabolic reactions require energy, but in the process of energy production, the body metabolizes organic matter into water and carbon dioxide and releases energy, and the final realization of this process requires the participation of oxygen.

So there is no oxygen, the tissues are not oxygen, the body cannot produce enough energy, the metabolism cannot be maintained, and the organism dies as a result of a long evolution.

Without oxygen, the mitochondria in your cells can't work, and if the cells don't work, you can't.

About 21% of the air is oxygen. Oxygen is the best way for living organisms to convert food into energy through aerobic respiration.

Breathing is extremely difficult, lips and face are blue, the heartbeat is rapid and weak, the patient is in a coma or semi-coma, cyanosis is obvious, breathing gradually slows down and weak, then irregular, until breathing stops, the heartbeat slows down and stops. The pupils are dilated and the light reflex is absent.
