Carbon dioxide.
Impact on man of increased carbon dioxide in the inhaled air

In many industries, there is still an effect on a person high concentrations of carbon dioxide (carbon dioxide) very noticeable. Previously, these were people who worked in fermentation shops, vegetable stores, in sanatoriums with narzanan baths in an atmosphere enriched with carbon dioxide, for 6-8 hours. Now, with the development of space technology, underwater research of the shelf of the seas and oceans, in other similar conditions, a person has to To continuously be in a closed space with an increased content of a very sensitive to the body of carbon dioxide weeks and even months.

The biological activity of this final product of the metabolism of a person who plays an important role in the organism homeostasis, each of us has repeatedly felt on himself. For example, being over an hour in a stuffy room with a large crowd of the people (in the cinema, at the lecture, next to the intensive smokers), and then coming out for fresh cool air, we have at least dizziness, or even sharp headaches, nausea and semi-resistant state. This phenomenon of "reverse action of carbon dioxide" was obtained in the experiment and described in detail in 1911 P. M. Albitsky. This occurs due to the transition from the atmosphere with an elevated content of carbon dioxide (hypercapinia) into normal atmospheric air (normal) and is due to the inertia of compensatory "anti-injection" mechanisms.

In providing human life conditions, the question of the adequacy of the gas environment of the work performed is often particularly sharp. That is, it is required in sealed objects to maintain such levels of carbon dioxide that would not have a negative impact on the performance and health of people. The actual data on the effect of the increased maintenance of carbon dioxide to the central nervous system is based on the maximum permissible concentrations (MPC) in closed inhabited rooms. various destination. Currently, most researchers believe that the long-term provision of a high level of human performance under the conditions of a hypercapnic medium is possible only at MPCs within 1% and lower. Such a concentration of carbon dioxide, in particular, is the limit, according to American scientists, in the compartments of nuclear submarines and in the cabins of spacecraft.

Many years of experience in observing people, long-term in a closed space, shows that they may have been in an atmosphere with a 3% content of carbon dioxide for many hours and even several days if its increase in the air is gradually, and the physical activity of a person is at the same time minimum. But in such conditions, mental and physical performance is dramatically reduced, the symptoms of the adverse action of carbon dioxide continue to increase.

Or can the human body adapt to the hypercapnia? Partially yes, maybe, but within no more than 1-1.5% concentration. At the same time, the excitability of the respiratory center decreases, the fan function decreases, the shifts of the blood system decrease. But with prolonged action on the body of the hypercapnic gas environment, along with the inclusion of compensatory reactions, there is a transition to a new level of functioning of many systems to ensure livelihoods. The consumption of oxygen is reduced, heat product flow decreases, the capacity of the vascular channel is reduced, the heart rate is slowed down. With apparent external well-being, the reactivity of the body is reduced to a number of external influences, especially requiring a rapid reaction of the cardiovascular system, increased oxygen support. A distinctive feature Long-term hypercapnia is a long negative aftermath. Despite the normalization of atmospheric respiration, in a long time, changes in the biochemical composition of blood, a decrease in immunological status, physical stability and other external influences are observed.

Consider in more detail the mechanisms of affecting carbon dioxide per person. This biologically active gas in the body binds to blood, enters a buffer reaction with hemoglobin, joining the free amino groups of its polypeptide chains and forming carbohemoglobin. Most of the carbon dioxide (about 80%) comes into contact with sodium, potassium and calcium cations, forming a blood bicarbonate system. The amount of carbon dioxide in the middle-weight human body is about 130 liters, in the hypercapnic medium it increases sharply: approximately 0.7 liters with an increase in the partial pressure of carbon dioxide in the inhaled air for each millimeter of the mercury pillar.

At high carbon dioxide concentrations, the frequency and depth of breathing increase. Especially sharply increases the ventilation of the lungs when the muscular work performed in the conditions of hypercapnia: 10-12 times or more. This is far from indifferent for the human body, complex, and often paradoxical reactions. At very large concentrations of carbon dioxide in the inhale air, the bronchial is due to the concentration, and at a concentration above 15% - the spasm of the voice slot.

Changes in the composition of blood with long-term hypercaps are to increase the number of erythrocytes, leukocytes and hemoglobin content, increasing blood viscosity, mobilizing uniform elements from blood depot. In the future, these mechanisms are substantially oppressed. There is a decrease in blood sugar content, glucose disposal is reduced. There is a decrease in glycogenic liver reserves, reduced glycogen content in the brain. The calcium content in the blood is reduced, and the demineralization of bones is enhanced, protein metabolism and residence of macroeergic phosphate compounds are slowed down. The content of ATP in cerebral tissue is especially significantly reduced. Increasing the content of carbon dioxide in the inhaled air initially causes heartbeat, then, on the contrary, - bradycardia. Due to the increase in blood viscosity, the load on the heart is significantly increased.

The main changes occur, of course, in the central nervous system, and they are carried by phase character with hyperkapin: at first an increase, and then reducing the excitability of nervous formations. The deterioration of conditionaloreflector activity is observed at concentrations close to 2%, and with a carbon dioxide content of 5-6%, a significant decrease in the amplitude of the caused brain potentials, desynchronization of the spontaneous electroencephalogram rhythm with the further oppression of the electrical activity of the brain occurs.

Outwardly, people have hypercups characterized by the emergence of a number of subjective symptoms, namely headaches, dizziness, feelings of breakdown, irritability, sleep disorders. Reducing performance accurately correlates with an increase in the percentage of carbon dioxide in atmospheric air. When this indicator approaches, the motor reaction time increases to 1%, the accuracy of the restoration response is reduced; With 1.5-2%, the mental human mental activity begins to change qualitatively, the differentiation, perception, RAM and allocation of attention are violated. With long-term operation in an atmosphere containing 3% carbon dioxide, substantial disorders of thinking, memory, fine motor coordination begins, the number of objects and errors of activity increase sharply, the number of hearing and vision disorders begin.

Morphological studies of the animal brain showed that changes in the endothelium of cerebral vessels, chromatolysis, vacuolaization and swelling of the cytoplasm of brain neurons occur when placed in 10% carbon dioxide for only 10 minutes.

In terms of production activities (especially in emergency situations), the impacts of simultaneously several extreme factors are important. In most cases, with such combined effects, carbon dioxide aggravates a negative impact on a person. With physical exertion in the diver or cosmonaut, carbon dioxide carries for itself nitrogen and, activating the diffusion of tissues in bubbles, with pressure drops, contributes to the occurrence of decompression (caisson) disease.

When considering the effect on the body, carbon dioxide in very high concentrations may impress that these issues are important only for narrow specialists and rare specialties. In fact, it is not. In rooms with poor ventilation, where many people and working equipment, the increased carbon dioxide content is not an exception, but rather a bad rule. The poorly ventilated kitchen of the residential apartment with the included gas burners is quickly filled with combustion products. The content of carbon dioxide can be significantly increased in the atmosphere of cities (especially in industrial smokers), in places of transportation of transport.

Carbon dioxide - CO 2 - is a colorless gas. It is 1.52 times heavier than air, it does not support combustion. In the atmospheric air it contains insignificantly small - about 0.04%.

To maintain normal vital activity, a person constantly consumes oxygen and highlights carbon dioxide. The concentration of these gases in the blood and tissues is at a certain level. The constancy of the inner gas environment is regulated by the work of the cardiovascular system and respiratory organs, that is, the strengthening or slowing down blood circulation and respiration. Carbon dioxide is distinguished from the body through the lungs during exhalation. On the surface at rest in 1 min. Man exhales an average of 250-300 cm 3 carbon dioxide gas. In the underwater works in the divers, the extraction of carbon dioxide increases sharply and reaches 1000-1600 cm 3 in 1 min.

Along with oxygen, carbon dioxide is a physiological respiratory regulator and blood circulation. With an increase in the content of CO 2 in the blood and tissues, there is increased and recess of breathing, strengthening and accelerating cardiac activity. In this way, the body is exempt from excess carbon dioxide. If it fails to do - poisoning occurs.

In atmospheric conditions in the lungs, or rather in alveolar air, the concentration of CO 2 is constantly maintained at a certain level (an average of 5.5%), and the body is very sensitive to its changes. Thus, with an increase in content of CO 2 by 0.2%, the volume of pulmonary ventilation 1 increases twice, and with a decrease to the same magnitude, a temporary natural stop of breathing (apnea) occurs.

When breathing with compressed air, when the partial oxygen pressure was increased and the blood is rich well (the lack of oxygen is not felt), respiratory regulation is reduced to maintaining the constancy of carbon dioxide voltage in the lungs. Respiratory efficiency under these conditions is estimated to ensure normal partial pressure CO 2 in alveolar air. Removal of carbon dioxide from the body with breathing with compressed air or artificial gas mixtures under elevated: pressure under these conditions is possible only with sufficient lung ventilation. A significant reduction in pulmonary ventilation inevitably leads to the accumulation of CO 2 and the poisoning of the body.

In divers, the poisoning of carbon dioxide can occur when working in a diving equipment of any type, as well as when it is in the recompression chamber, when the content of CO 2 in the inhaled air is above 1% (given to normal pressure).

Causes of carbon dioxide accumulation.

1. In ventilated equipment, poisoning may occur with insufficient ventilation of the player or the cessation of air supply from the surface due to the malfunction of the diving pump (compressor), cliff or squeezing the air hose, reduce its lumen due to the freezing.
2. In oxygen, devices, the causes of excess accumulation of carbon dioxide are most often: malfunction of the valve inhale, low quality or complete testing of the chemical clot, the absence of a himplotor in the box. Separation of carbon dioxide through the absorber box can be observed and with good quality, but with incomplete fill in them box. In this case, firstly, it becomes a smaller time of the absorber against the calculated due to the reduction of the absorbing surface and, secondly, when the box is tilted, the exhaled air passes through the wall of the box, bypassing the absorber.

   With the malfunction of the inspirate valve, the exhaled mixture only partially passes through the himbrogen box, the main mass returns to the breathing bag through the inhalation valve defect, and in the bag, the concentration of CO 2 increases very quickly.

3. In an autonomous type of equipment on compressed air, carbon dioxide does not accumulate, as the exhale is carried out into the water. The poisoning is possible only if the charging of the cylinders was performed by air with an admixture of carbon dioxide or exhaust gases.
4. In the recompression chamber, the cause of poisoning CO 2 is a violation of the ventilation mode, which is established depending on the volume of the chamber and the number of persons in it.

Signs of poisoning with carbon dioxide. Air breathing with an admixture of up to 1% CO 2 can be carried out for a long time without significant changes in the well-being of diver. With an increase in concentration of over 2-3%, typical signs of poisoning appear: shortness of breath, increasing with the slightest physical exertion, headache, dizziness, noise and ringing in the ears, nausea, saliva, sweating of the face. If in the inhaled air, carbon dioxide reaches 5-6%, shortness of breath and headache becomes unbearable, the general weakness increases rapidly. Further increase in concentration of CO 2 causes convulsions, loss of consciousness, deep sleep. Soon, convulsions stop, breathing becomes more rare and superficial. Then breathing stops and death can come.

In the event of a rapid accumulation of carbon dioxide, which is observed when operating in oxygen equipment, where the volume of closed space is limited to 8-10 liters, the poisoning occurs quickly, without gradual manifestation of signs. Sometimes the loss of consciousness comes suddenly.

Poisoning with carbon dioxide in ventilated equipment occurs slowly, since the volume of the square is large (60-80 liters) and for accumulating the poison concentration of CO 2 requires more time.

First aid. At the first signs of poisoning, the diver must stop working, report on it to the surface and require an increase in air supply for better ventilation of the player. If these measures do not lead to improving well-being, it should rise to the surface with decompression regime. During the lifting, it is necessary to ventilate a jade, and on the outlet of the surface to breathe oxygen for 15-20 minutes.

When signs of poisoning during operation in oxygen equipment, it is necessary to stop working, replace the breathing mixture in the breathing bag and go to the surface.

In severe cases of poisoning with the loss of consciousness under water, the victims are removed to the surface with the help of an insuring diver, they quickly exempt from equipment and proceed to assistance (dacha oxygen, artificial respiration in the absence of breathing, the introduction of heart activity stimulants and respiration).

Carbon dioxide poisoning prevention. When working in ventilated equipment, the compressor, pumps and sections of cylinders with compressed air should be in good condition. You should systematically produce workshop and test hoses. Ventilation in the scaffle of maintaining within 80-100 l min. The control over the quality of air supplied to the diver is carried out by calculation, and the air flow rate is determined by the pressure gauge (when air is supplied from the compressor) or by the number of turns of the pump (if the air supply from the diver pump).

In winter conditions, it is impossible to freeze hoses.

When working in oxygen equipment before each dive, it is necessary to carry out a working test of equipment, paying particular attention to the health of the inhalation and exhalation valves. Before charging the cartridge, check the quality of the chimplotor or regenerative substance. The initial saturation of the chimplottor with carbon dioxide should not exceed 15 l / kg, and the regenerative substance is 20 l / kg. It is impossible to increase the time of stay under water over the calculated, during which the chimplotter acts.

In order to avoid errors in charging the breathing apparatuses, it is not allowed to rack the spent himplotor into empty drums from under the chemical clot.

Concentration of carbon dioxide in clean atmospheric air: carbon dioxide - 0.04%

For comparison, the typical level of CO2 in the atmosphere of megalopolises is 0.06-0.08%, and this is exactly the air that serves ventilation into the room.

There is a question, but will the ventilation help?

Ventilation helps reduce the concentration of CO2 carbon dioxide in the premises only if you live or work in an environmentally friendly place, but it is almost impossible to maintain CO2 carbon dioxide concentration in rooms within atmospheric, i.e. 0.04%.

How many CO2 highlights a man when breathing

It is known that one person in a calm state in one hour consumes 20-30 liters of oxygen with a separation of 18-25 liters of carbon dioxide. In the air exhaled, carbon dioxide is 100 times larger than in clean atmospheric air. Knowing it, it becomes clear why gas, which is included in the exchange processes of the human body, under certain circumstances may cause him harm. The last studies of Western scientists show that carbon dioxide indoors is a substance that even in low concentrations may be addicted to health and human performance.

(In the article, as a unit of measurement of CO2, uses PPM (Parts Per Million or CO2 particles per million air particles). 1000 ppm \u003d 0.1% CO2 content.)

The excessive concentration of carbon dioxide in the air can lead to negative changes in the blood and the urine of man and human DNA.

Scientists have found that carbon dioxide even in low concentrations negatively affects the human cell membrane and can lead to such biochemical changes in the body as an increase in PSO2, an increase in the concentration of bicarbonate ions, acidosis, etc., in its influence carbon dioxide is also toxic for humans. like nitrogen dioxide (NO2)

The increased concentration of carbon dioxide affects human health, since under its effection, blood pH decreases, which leads to acidosis, the minimum effect of the consequence of acidosis is the state of overexcitation and moderate hypertension. As the degree of acidosis increases, drowsiness and the state of anxiety appears. One of the consequences of these changes is to reduce the desire to show physical activity and receive from this pleasure.

Under the influence of carbon dioxide, at a concentration of carbon dioxide (CO2) above 800 PPM, an increase in the number of oxidative stress markers in DNA is observed, the number of markers is directly connected with the time of finding a person in the room.

Carbon dioxide in the school class increases the incidence and reduces student performance

Special attention should be paid to the quality of air, which to breathe children in classes, the concentration of carbon dioxide (CO2) in the air of the classroom can increase several times by the end of the occupation.

Children who are studying in classes with a high concentration of carbon dioxide, often observed heavy breathing, shortness of breath, dry cough and rhinitis, these children have a weakened nasopharynk.

The increase in the concentration of carbon dioxide (CO2) in the room leads the emergence of asthma attacks in asthmatics children.

Due to increasing the concentration of carbon dioxide in schools and higher educational institutions, the number of skipping lessons by students on illness is increasing. Respiratory infections and asthma are essential diseases in such schools.

Increased concentration of carbon dioxide in the class negatively affects the results of children's study, reduces their performance.

The problem of increased concentration of carbon dioxide is also characteristic of kindergartens, and the most strongly level of CO2 rises in the bedrooms of kindergartens

The report on the health status of children in Russian Federation (According to the results of the All-Russian clinical examination 2002), it was noted that the diseases of the respiratory organs dominate the incidence of children in the age of the age.

Doctor of Medical Sciences Boris Revich believes that "In Russian classes it is difficult to breathe due to plastic windowswhich are installed when repairing schools. The room closed with plastic turns into a closed chamber, and carbon dioxide in such conditions may exceed the standards many times. However, in our country there are practically no data on this topic, and work on this issue is not conducted. "

Carbon dioxide in office space reduces the productivity of employees, worsens their health status, leads to a patient building syndrome (SBS)

Measures. Moscow has shown that in a number of offices, the concentration of carbon dioxide (CO2) reached 2 000 PPM and above.

Research has shown. That when the CO2 carbon dioxide concentration is above 800 -1000 PPM, office buildings begin to experience symptoms of the SBS: irritation of mucous membranes, dry cough, headache, reduced performance. Eye inflammation, nasal congestion, ride inflammation, problems associated with the respiratory system, dry cough, headache, fatigue and complexity with a concentration of attention, and carbon dioxide is one of the main causes of SBS development.

To replenish the room with air with a large oxygen content, it is necessary to pull the spent air with a high content of carbon dioxide and other substances.

From here, simple requirements arise:

1. The room must have a sufficient volume so that a person is always enough to breathe. Therefore, when buying a home it is desirable to count not only square meters, but also cubic.
2. It is necessary to ensure both the influx of air and its outflow. In the absence of one or another, the process of air intake occurs for a long time and does not sleep for an increase in the concentration of carbon dioxide. Example. In old houses, everything was done very competently - the receipt of fresh air was evenly carried out through the slots in the windows and doors, and removing the spent - through exhaust ventilation in the toilet. After installing modern hermetic windows and doors, a person abruptly limited not only the flow of fresh air, but also the outflow of spent. Support valves help, but they supply the air locally, compared to the uniform distribution of the old window slots. Natural or active ventilation should provide such an air exchange, so that at any time in the presence of a different number of people, the content of oxygen, carbon dioxide and many other components of air has always been in a comfortable limit.
3. In winter it is possible to provide heating of the incoming air. The simplest option is the installation of the supply valve between the windowsill and the heating radiator (modern gap analog). In order not to dispose of heat with the separation from the room, you can use the recovery systems when the outgoing stream is heated incoming.
4. The carbon dioxide sensor allows you to enable ventilation and adjust its performance in automatic mode so that the energy is spent only in the presence of a person with an increase in carbon dioxide concentration.
5. About the dangers of air conditioner. In addition to the cold air flow, often falling on the heads of people, the temperature difference when exiting the street, bacteria, comfortably living in the coolness, there is a danger that is rarely mentioned. In order to save electricity, the operation of the air conditioner closes all windows. At the same time, the concentration of carbon dioxide quickly reaches a considerable value and is cooled, but the poor is oxygen. Therefore, the window must be kept open - health is more expensive.

Life on Earth billions of years has developed at a high concentration of carbon dioxide. And carbon dioxide has become a necessary component of metabolism. The cells of animals and human carbon dioxide need about 6-7 percent. And oxygen - only 2 percent. This fact was installed embryologists. The fertilized egg in the first days is almost in an oxygen-free medium - oxygen is simply destroyed for it. And only as the implantation and formation of placental blood circulation, an aerobic method of energy production is gradually begins to be carried out.

The fetal blood contains little oxygen and a lot of carbon dioxide compared to the blood of an adult organism.

One of the fundamental laws of biology states that every organism in its individual development repeats the entire path of the evolution of its species, ranging from a unicellular creature and ending with a highly developed person. And in fact, we all know that in the womb of the mother we first were the simplest unicellular creature, then a multicellular sponge, then the germ was like a fish, then on triton, a dog, a monkey, and, finally, per person.

Evolution undergoes not only the fruit itself, but also its gas medium. The blood of the fetus contains oxygen 4 times less, and carbon dioxide is 2 times more than an adult. If the blood of the fetus start saturate with oxygen, it instantly dies.

Excess oxygen is destroyed for all living things, because oxygen is a strong oxidizing agent, which under certain conditions can destroy the cell membranes.

In a newborn baby, after the implementation of the first respiratory movements, the high content of carbon dioxide during the taking of blood from the umbilical artery was also detected. Does this mean that the mother's body seeks to create a medium for normal fetus development, what was on the planet billions of years ago?

And take the other fact: the mountaineers almost do not suffer as ailments as asthma, hypertension or angina, which are common among citizens.

Is it because at an altitude of three to four thousand meters the oxygen content in the air is much smaller? With an increase in height, the air density decreases, respectively, the amount of oxygen in the inhaled volume is reduced, but no matter how paradoxically, it has a positive effect on human health.

Remarkable is the fact that exercises causing hypoxia on the plain are more useful for health than just staying in the mountains even for the one who easily transfers the mountain climate. This is due to the fact that breathing sparse mountain air, man breathes deeper than usual to get more oxygen. Deeper breaths automatically lead to deeper exhalations, and since we constantly lose carbon dioxide with exhale, the deepening of breathing leads to too much of its losses, which may adversely affect health.

Note along the way, that the mountain disease is associated not only with a deficiency of oxygen, but also with excessive loss of carbon dioxide with deep breathing.

The benefits of such aerobic cyclic exercises are running, swimming, rowing, bike, skis, etc. largely determined by the fact that moderate hypoxia mode is created in the body when the body's need for oxygen exceeds the ability of the breathing apparatus to satisfy this need, and hyperkapin when In the body of carbon dioxide produces more than the body can highlight the lungs.

Theory of life in a brief statement is as follows:

carbon dioxide - the base of the power of all living on Earth; If it disappears from the air, all living will die.

carbon dioxide is the main regulator of all functions in the body, the main environment of the body, vitamin of all vitamins. It regulates the activity of all vitamins and enzymes. If it is missing, all vitamins and enzymes work badly, defective, abnormally. As a result, the metabolism is violated, and this leads to allergies, cancer, salting deposition.

In the process of gas exchange, oxygen and carbon dioxide are of paramount importance.

Oxygen enters the body along with air, through bronchi, then falls into the lungs, from there - in blood, and from the blood - in the tissue. Oxygen is represented by a kind of valuable element, it's a source of any life, and someone even compares it with the concept of "Prana" known from yoga. No more wrong opinions. In fact, oxygen is a regenerating element that serves to clean the cell from all its waste and in some way to burn it. Cell garbage should be constantly cleaned, otherwise heightened intoxication or death occurs. The most sensitive to intoxication of the brain cell, they die without oxygen (in the case of apnea) four minutes later.

Carbon dioxide passes this chain in the opposite direction: it is formed in the tissues, then enters the blood and from there through the respiratory tract is derived from the body.

In a healthy person, these two processes are in a state of constant equilibrium, when the ratio of carbon dioxide and oxygen is the proportion of 3: 1.

Carbon dioxide, contrary to widespread opinion, is necessary for the body no less than oxygen. Carbon dioxide pressure affects the bark of the brain, respiratory and vessel-motorware centers, carbon dioxide also provides a tone and a certain degree of readiness for the activities of various departments of the central nervous system, is responsible for the tone of vessels, bronchi, metabolism, the secretion of hormones, the electrolyte composition of the blood and fabrics. So, indirectly affects the activity of enzymes and the speed of almost all biochemical reactions of the body. Oxygen serves as an energy material, and its regulatory functions is limited.

Carbon dioxide is the source of life and the regenerator of the function of the body, and oxygen - energy.

In antiquity, the atmosphere of our planet was strong saturated with carbon dioxide (Over 90%), it was, and is now, a natural building material of living cells. As an example, plant biosynthesis reaction - carbon dioxide absorption, carbon utilization and oxygen isolationAnd precisely in those days on the planet there existed very magnificent vegetation.

Carbon dioxide also participates in the biosynthesis of animal protein, in this some scientists see possible cause There is a lot of millions ago of giant animals and plants.

The presence of lush vegetation gradually led to a change in the composition of the air, reduced carbon dioxidebut the internal conditions of the cells are still determined high content carbon dioxide. The first animals appeared on the ground and fed by plants were in the atmosphere with high carbon dioxide content. Therefore, their cells, and later created on the basis of the ancient genetic memory of the cells of modern animals and humans, need carbonate medium inside itself (6-8% of carbon dioxide and 1-2% oxygen) and blood (7-7.5% carbon dioxide ).

Plants disposed almost all carbon dioxide And its main part, in the form of carbon compounds, together with the death of plants, got into the ground, turning into minerals (coal, oil, peat). Currently, atmosphere contains about 0.03% of carbon dioxide and approximately 21% oxygen.
It is known that in the air there is approximately 21% oxygen. At the same time, its decrease to 15% or an increase of up to 80% will not have any influence on our body. It is known that in exhaled from the lung air, it contains from 14 to 15% oxygen, which is what the method of artificial respiration "mouth in the mouth" is used, which would otherwise be ineffective. Of the 21% oxygen, only 6% are adsorbed by body tissues. Unlike oxygen to change the concentration of carbon dioxide in one direction or another, only 0.1%, our body immediately reacts and tries to return it to the norm. From here we can conclude that

carbon dioxide is about 60-80 times more important than oxygen for our body.

Therefore, we can say that the efficiency of external respiration can be determined by the level of carbon dioxide in the alveoli.

But for normal vital activity in the blood, there should be 7-7.5% of carbon dioxide, and in alveolar air - 6.5%.

From the outside it is impossible to obtain it, since in the atmosphere almost contained carbon dioxide. Animals and people get it in full sword of food, as proteins, fats, carbohydrates built on a carbon basis, when burning with oxygen in the tissues, invaluable carbon dioxide is formed - the basis of life. Reducing carbon dioxide in the body below 4% is death.

The CO2 task is to cause a respiratory reflex. When its pressure rises, a network of thin nerve endings (receptors) immediately sends a message to the bulbs of the spine and brain, the respiratory centers, from where and follow the team to start the respiratory act. Therefore, carbon dioxide can be considered a watchdogs that signals the danger. When hyperventilation, the dog is temporarily exposed to the door.

Carbon dioxide regulates metabolism, as it serves as raw materials, and oxygen goes on burning organic substances, that is, he is only energy.

The role of carbon dioxide in the vital activity of the body is very diverse. We present only some of its basic properties:

• it is an excellent vasodilator;
• is a reassureer (tranquilizer) of the nervous system, which means an excellent anesthetic agent;
• participates in the synthesis of amino acids in the body;
• plays a big role in the excitation of the respiratory center.

Most often because Carbon dioxide is vitalWith its excessive loss to one degree or another, protective mechanisms trying to stop it removal from the body. These include:
- spasm of vessels, bronchi and spasm smooth musculature of all organs;
- narrowing of blood vessels;
- an increase in the secretion of mucus in bronchi, nasal strokes, the development of adenoids, polyps;
- sealing membranes due to cholesterol deposits, which contributes to the development of cloth sclerosis;

All these moments with difficulty oxygen flow in cells for downlook the content of carbon dioxide in the blood (Verigo-boron effect) lead to oxygen starvation, slowing the venous blood flow (with the subsequent resistant extension of the veins).

More than a hundred years ago, the Russian scientist verigue, and then the Danish physiologist Christian Bohr discovered the effect called by their name.

It lies in the fact that with the deficiency of carbon dioxide in the blood, all biochemical processes of the body are violated. So, the deeper and intense the person breathes, the greater the oxygen starvation of the body!
The larger the body (in the blood) C02, the greater 02 (according to arteriols and capillaries) reaches the cells and is absorbed by them.

The oversupply of oxygen and lack of carbon dioxide lead to oxygen starvation.

It was found that without the presence of carbon dioxide, oxygen cannot be released from the associated state with hemoglobin (the effect of the verig-boron), which leads to oxygen starvation of the body, even at the high concentration of this gas in the blood.

The more noticeably the content of carbon dioxide in arterial blood, the easier the oxygen from hemoglobin and the transition to the tissues and organs, and vice versa, the lack of carbon dioxide in the blood contributes to the fastep of oxygen in red blood cells. The blood circulates in the body, and the oxygen does not give! A paradoxical state occurs: the oxygen in the blood is sufficient, and the organs signal about its extreme disadvantage. A person begins to choke, seeks to breathe and exhale, trying to breathe more often and also flips carbon dioxide out of blood, fixing oxygen in red blood cells.

It is well known that during intensive sports in the blood sports athlete, the carbon dioxide content increases. It turns out that this is how sport and useful. And not just a sport, but any charging, gymnastics, physical work, in one word - movement.

The increase in CO2 level contributes to the expansion of small arteries (the tone of which determines the number of functioning capillaries) and an increase in cerebral blood flow. Regular hypercupnia activates the production of vascular growth factors, which leads to the formation of a more branched capillary network and optimizing the tissue circulation of the brain.

You can also acidify the blood in capillaries with lactic acid and then the effect of second breathing occurs during physical long-term loads. To accelerate the appearance of second breathing, athletes are recommended to delay their breathing as possible. The athlete runs a long distance, no strength, everything is like a normal person. A normal person stops and says: "Everything, I can no longer." The athlete delays his breath and his second breathing opens, and he runs on.

Breathing to some extent controlled by consciousness. We can force ourselves to breathe more often or less often, or even delay breathing at all. However, how long we tried to restrain the breath, the moment occurs when it becomes impossible. The signal for the next breath is not the lack of oxygen, which could seem logical, and excess carbon dioxide. It is accumulated carbon dioxide gas that is a physiological stimulator of breathing. After opening the role of carbon dioxide, it began to add to gas mixtures of scubaers to stimulate the operation of the respiratory center. The same principle is used with anesthesia.

All breathing art is to hardly exhale carbon dioxide, lose it as little as possible. Breathing of yogis just complies with this requirement.

And the breath of ordinary people is chronic hyperventilation of the lungs, excessive removal of carbon dioxide from the body, which causes the occurrence of about 150 severe diseases, are often referred to in civilization diseases.

The role of carbon dioxide in the development of arterial hypertension

Meanwhile, the statement that the root cause of hypertension is the insufficient concentration of carbon dioxide In the blood, it is checked very simple. We just need to find out how much carbon dioxide It is in the arterial blood of hypertensive and healthy people. This was what was done in the early 1990s by Russian scientists-physiologists.

The studies of the gas composition of large groups of the population of different ages, the results of which can be read in the book "Physiological role of carbon dioxide and human performance" (N. A. Aghajanyan, N. P. Krasnikov, I. N. Polunin, 1995) allowed to make an unequivocal The conclusion about the reason for the permanent spasm of microscopes - hypertension arterioles. The overwhelming majority of the surveyed elderly people at rest in arterial blood contains 3.6-4.5% carbon dioxide (at a rate of 6-6.5%).

In this way, actual evidence was obtained that the root cause of many chronic ailments characteristic of the elderly, - losing their ability to constantly maintain carbon dioxide in arterial blood. Close to normal. And the fact that young and healthy carbon dioxide people In the blood of 6 - 6.5% - a long-known physiological axiom.

From what depends the concentration of carbon dioxide In arterial blood?

Carbon dioxide C02. Constantly formed in the cells of the body. The process of its removal from the body through the lungs is strictly regulated by the respiratory center - the brain department, controlling external breathing. In healthy people at every moment of time, the level of ventilation of the lungs (frequency and depth of breathing) is such that C0 2 It is removed from the body exactly in such a quantity so that it always remains in arterial blood at least 6%. Truly healthy (in physiological)) the body does not allow reducing carbon dioxide content Less than this figure and increase more than 6.5%.

It is interesting to note that the values \u200b\u200bof a huge number of various indicators defined in the studies conducted in clinics and diagnostic centers, people have a lot of young and elderly. And only carbon dioxide content indicators In the blood differ by about one and a half times. The other is so bright and specific differences between healthy and patients do not exist.

Carbon dioxide is a powerful vasodilator (expanding vessels)

Carbon dioxide, this is a vasodilator acting directly to the vascular wall, and therefore, with a breath delay, warm skin is observed. Respiratory delay is an important component of the body flex. Everything happens as follows: You are performing special breathing exercises (inhale, exhale, then pull the stomach and delay your breath, take a tensile position, consider up to 10, then inhale and relax).

Bodyflex classes contribute to the enrichment of the organism with oxygen. If you delay your breath for 8-10 seconds, carbon dioxide accumulates in the blood. This contributes to the expansion of the arteries and prepares the cells to a much more efficient absorption of oxygen. Additional oxygen helps to cope with many problems, such as overweight, disadvantage of energy and poor well-being.

Currently, the carbon dioxide scientists doctors look at the powerful physiological factor in the regulation of numerous organism systems: respiratory, transport, vessels, excretory, hematopoietic, immune, hormoneal, etc.

It has been proven that the local exposure to carbon dioxide on a limited type of tissue is accompanied by an increase in volumetric blood flow, an increase in the speed of extraction of oxygen by tissues, enhancing their metabolism, recipe sensitivity, enhancing reparative processes and activation of fibroblasts. The general reactions of the organism on the local exposure to carbon dioxide include the development of moderate gas alkalosis, the enhancement of erythro and lymphoposhesis.

The subcutaneous injections of CO2 are hyperemia, which has resorbative, bactericidal and anti-inflammatory, painkillers and antispasmodic effects. Carbon dioxide for a long period improves the bloodstream, blood circulation of the brain, heart and vessels.

Carboxherapy helps when signs of aging of the skin, contributes to the correction of the figure, eliminates many cosmetic defects and even allows you to fight cellulite.

Increased blood circulation in the hair growth zone allows you to wake "sleeping" hair follicles, and this effect allows you to use carboxyterepia when bald. What happens in subcutaneous tissue? In fatty cells, under the action of carbon dioxide, lipolysis processes are stimulated, as a result of which the volume of adipose tissue decreases. The procedure course helps to get rid of cellulite or at least reduces the severity of this unpleasant phenomenon.

Pigment stains, age-related changes, scar changes and stretch marks are some more readings for this method. In the area of \u200b\u200bthe carboxherapy face, it is used to correct the shape of the lower eyelid, as well as to combat the second chin. The technique is prescribed at Cooperose, with acne disease.

So, it becomes clear that carbon dioxide in our body performs numerous and very important functions, and oxygen is only an oxidizing agent of nutrients in the process of generating energy. But more so, when the "burning" of oxygen occurs not to the end, very toxic products are formed - free active forms of oxygen, free radicals. It is they who are the main starting mechanism in the launch of aging and rebirth cells of the body, distorting very thin and complex intracellular structures with uncontrollable reactions.

From the above, an unusual conclusion is:

The art of respiration is to hardly exhale carbon dioxide and lose it as little as possible.

As for the essence of all respiratory techniques, they basically make the same thing - increase the content in the blood of carbon dioxide due to the delay of breathing. The only difference is that in different techniques it is achieved in different ways - or due to the delay of breathing after the inhalation, or after the exhalation, or due to the elongated exhalation, or by elongated inhalation, or combinations thereof.

If you add carbon dioxide carbon dioxide to pure oxygen and give rise to a seriously ill person, then its condition will improve to a greater extent than if it was breathing with pure oxygen. It turned out that carbon dioxide to a certain limit contributes to a more complete absorption of oxygen by the body. This limit is 8% CO 2. With an increase in the content of CO 2 to 8%, an increase in the assimilation of 2, and then with an even greater increase in the content of CO 2, the assimilation of 2 begins to fall. It's not to derive the body, but "loses" carbon dioxide with exhaled air and some restriction of these losses should have a beneficial effect on the body.

If you even more reduce your breath, as yoga advise, then a person will develop ultra-hardness, high health potential, all the prerequisites for longevity will emerge.

When performing such exercises, we create hypoxia in the body - lack of oxygen, and hypercapinia - an excess of carbon dioxide. It should be noted that even with the longest breathing delays, the content of CO 2 in the alveolar air does not exceed 7%, so you do not have to be afraid of the harmful effects of excessive doses of CO 2.

Studies show that the impact of metered hypoxic-hypercapnic workouts for 18 days to 20 minutes is accompanied by statistically significant improvement in well-being by 10%, improving the ability to logically thinking by 25% and an increase in the amount of RAM 20%.

We must try to breathe shallow all the time (so that the breath is not noticeable, nor heard) and rarely, striving to stretch the automatic pouas after each exhalation.

Yogi say that each person from birth has been released a certain number of breathing and you need to take this stock. In such an original form, they urge to reduce the frequency of breathing.

From the number of carbon dioxide in the human blood stream depends on the normal functioning of all life systems. Carbon dioxide increases the body's resistance to bacterial and viral infections, participates in the exchange of biologically active substances. With physical and intellectual loads, carbon dioxide helps to maintain the equilibrium of the body. But a significant increase in this chemical compound in the surrounding atmosphere impairs human well-being. The harm and use of carbon dioxide for the existence of life on Earth has not yet been studied.

Characteristic features of carbon dioxide

Carbon dioxide, coal anhydride, carbon dioxide - a gaseous chemical compound that does not have color and smell. The substance is 1, 5 times heavier than air, and its concentration in the Earth's atmosphere is approximately 0.04%. A distinctive feature of carbon dioxide is the absence of a liquid form with an increase in pressure - the connection immediately goes into a solid state, known as "dry ice". But when creating certain artificial conditions Carbon dioxide takes fluid shape, which is widely used for its transportation and long-term storage.

Interesting fact

Carbon dioxide does not become an obstacle for ultraviolet rays that come to the atmosphere from the Sun. But the infrared radiation of the Earth is absorbed by carbon anhydride. This is the cause of global warming since the formation of a huge amount of industrial production.

During the day, the human body absorbs and metabolizes about 1 kg of carbon dioxide. It takes an active part in the exchange of substances, which occurs in soft, bone, joint tissues, and then falls into the venous direction. With blood flow, carbon dioxide enters the lungs and leaves the body with every exhale.

The chemical is in the human body mainly in the venous system. The capillary network of pulmonary structures and arterial blood contain a small concentration of carbon dioxide. The term "partial pressure" is used in medicine, which characterizes the concentration ratio of the compound relative to the entire blood volume.

Therapeutic properties of carbon dioxide

The penetration of carbon dioxide into the body causes a respiratory reflex in humans. Increasing the pressure of the chemical compound provokes thin nerve endings to send pulses to the receptors of the head or (and) spinal cord. This is how the processes of inhalation and exhalation occur. If the level of carbon dioxide in the blood begins to rise, then the lungs accelerate its separation from the body.

Interesting fact

Scientists have proven that a significant lifespan of people living in highlands is directly related to the large content of carbon dioxide in the air. It improves immunity, normalizes metabolic processes, strengthens the cardiovascular system.

In the human body, carbon dioxide is one of the most important regulators, acting as a basic product along with molecular oxygen. The role of carbon dioxide in the process of human vital activity is difficult to overestimate. The main functional features of the substance include the following:

• has the abilities to cause a persistent expansion of large vessels and capillaries;
• able to provide a sedative effect on the central nervous system, provoking anesthetic effect;
• takes part in the production of major amino acids;
• he excites the respiratory center with an increase in the concentration in the bloodstream.

If the body has an acute carbon dioxide deficiency, then all systems are mobilized and increase their functional activity. All processes in the body are aimed at replenishing carbon dioxide reserves in tissues and bloodstream:

• the vessels are narrowed, the bronchospasm is developing a smooth muscles of the upper and lower respiratory tract, as well as blood vessels;
• bronchi, bronchioles, lung structural departments secrete an increased amount of mucus;
• reduced permeability of large and small blood vessels, capillaries;
• cell membranes begins to postpone cholesterol, which causes their seal and tissue sclerosis.

The combination of all these pathological factors in combination with the small intake of molecular oxygen leads to hypoxia tissues and a decrease in blood flow rate in veins. Especially acutely felt oxygen starvation in brain cells, they begin to collapse. The regulation of all systems of vital activity is violated: brain swell and lungs, the rhythm of heart abbreviations is reduced. In the absence of medical intervention, a person may die.

Where used carbon dioxide

Carbon dioxide is not only in the human body and in the surrounding atmosphere. Many industrial production actively use chemicals at various stages technological processes. It is used as:

• stabilizer;
• catalyst;
• primary or secondary raw materials.

Interesting fact

Oxygen dioxide contributes to the conversion of grapes to a delicious tart homemade wine. In the fermentation of sugar contained in berries, carbon dioxide is distinguished. He gives sparkling drink, allows you to feel the buzzing bubbles in your mouth.
On packaging of food, carbon dioxide is hidden under the E290 code. As a rule, it is used as a preservative for long-term storage. When baking delicious cupcakes or pies, many mistresses add a baking powder into the dough. In the process of cooking, air bubbles are formed, making a piece of lush, soft. This is carbon dioxide - the result of a chemical reaction between sodium bicarbonate and food acid. Amateurs aquarium fish A colorless gas is used as an activator of the growth of aquatic plants, and manufacturers of automatic carbon dioxide plants are placed in fire extinguishers.

Harm coal anhydride

Children and adults love a variety of effervescent drinks for the air bubbles contained in them. These accumulations of air are pure carbon dioxide, released when unscrewing a bottle cap. Used in such capacity, it does not bring human body any benefit. Finding into the gastrointestinal tract, coal anhydride annoys the mucous membranes, provokes damage to epithelial cells.

For a person with gastric diseases, the use of carbonated beverages is extremely undesirable, since the inflammatory process and the ulceration of the inner wall of the digestive system organs increase under their exposure.

Gastroenterologists prohibit drinking lemonade and mineral water to patients with such pathologies:

• acute, chronic, catarrhal gastritis;
• gastric ulcer and duodenal intestine;
• duodenitis;
• reduction of intestinal peristals;
• benign and malignant neoplasms of the gastrointestinal tract.

It should be noted that on the statistical data of WHO more than half of the inhabitants of the planet, the Earth suffer from one or another form of gastritis. The main symptoms of the disease of the stomach: sour belly, heartburn, bloating and pain in the epigastric area.

If a person is unable to abandon the use of drinks with carbon dioxide, then he should be able to choose from a weathered mineral water.

Experts advise eliminate lemonade from everyday diet. After the statistical studies conducted in people who have durable sweet water with carbon dioxide, diseases were identified:

• caries;
• endocrine disorders;
• increased fragility of bone tissue;
• liver fluid dystrophy;
• formation of concrections in the bladder and kidneys;
• violations of metabolism of carbohydrates.

Employees of office premises that are not equipped with air conditioning are often experiencing painful headaches, nausea, weakness. This condition in humans occurs with excess accumulation in carbon dioxide room. Permanent finding in such an environment leads to acidosis (increasing blood acidity), provokes a decrease in the functional activity of all life systems.

The benefits of carbon dioxide

The healing effect of carbon dioxide on the human body is widely used in medicine in the therapy of various diseases. So, recently enjoy the great popularity of dry carbon dioxide. The procedure consists in the effects of carbon dioxide on the human body in the absence of extraneous factors: water pressure and ambient temperature.

Cosmetic salons I. medical institutions Offer customers to carry out unusual medical manipulations:

• pneumopuncture;
• carboxiterpia.

Under the complex terms, gas injections or injections with carbon dioxide are hidden. Such procedures can be attributed both to the varieties of mesotherapy and to the methods of rehabilitation after suffering severe diseases.

Before conducting these procedures, you should visit the attending physician for advice and thorough diagnosis. Like all therapy techniques, carbon dioxide injections have contraindications to use.

The beneficial properties of carbon dioxide are used in cardiovascular therapy, arterial hypertension. And dry baths reduce the content of free radicals in the body, have a rejuvenating effect. Carbon dioxide increases human resistance to viral and bacterial infections, strengthens immunity, increases vitality.

Most people believe that carbon dioxide is harmful. It is not surprising, because we were told about the negative properties of CO2 as early as school in the lessons of biology and chemistry. Representing carbon dioxide exclusively as a harmful substance, the teachers usually silent about his positive role within our body.

It is meanwhile in meanwhile, because carbon dioxide, or carbon dioxide, is an important member of the respiratory process. How does carbon dioxide acts on our body and what is it useful?

When we do inhale, our lungs are filled with oxygen, while at the bottom of the body - alveoli - carbon dioxide is formed. At this moment there is an exchange: oxygen goes into the blood, and carbon dioxide is distinguished from it. And we exhale.

Repeating about 15-20 times in a minute Breath launches all the livelihoods of the body,
And the carbon dioxide formed at the same time affects many vital functions immediately. What is useful carbon dioxide for a person?

CO2 regulates the excitability of nerve cells affects the permeability of cell membranes and the activity of enzymes, stabilizes the intensity of hormone production and their degree of efficiency, participate
In the process of binding to proteins of calcium and iron ions.

In addition, carbon dioxide is the final metabolic product. Exhausted we remove unnecessary components that have arisen during the metabolism and clean our body. The metabolic process is continuous, so we need to remove the final products constantly.

It is important not only for the presence, but also the amount of CO2 in the body. The normal level of content is 6-6.5%. This is enough to ensure that all "mechanisms" in the body worked correctly, and you felt good.

The lack of or excess carbon dioxide in the body leads to two states: hypokapinia
and hypercapnia.

Hypopania - This is a lack of carbon dioxide in the blood. Occurs with deep rapid breathing when the body allocates too a large number of carbon dioxide. For example, after intensive sports. Hypopelia can lead to a light dizziness or loss of consciousness.

Hypercapnia - This is an overabundance of carbon dioxide in the blood. There is indoors with poor ventilation. If the concentration of CO2 in the room will exceed the norm, then its level in the body will also be higher.

Because of this, a head may get sick, nausea and drowsiness appear. Especially often hypercupnia arises in winter from office workers, as well as in large queues. For example, in the mail or in the clinic.

The surplus of carbon dioxide may occur in extreme situations, for example, when breathing under water.

We will tell you more about the consequences of hypercupinia and ways to combat her in one of the following articles. Today we will focus on hinders and its treatment.

As mentioned above, carbon dioxide affects many processes in our body, so it is so important that its level holds within the normal range. And one of the types of respiratory gymnastics will help to bring the CO2 content.

But such phrases look not very convincing, especially when we want to solve some particular problem or get rid of a certain illness. Let's figure out how carbon dioxide helps
and respiratory gymnastics in specific cases.

Let's start with the fact that in the process of classes on a simulator or standard respiratory practices, the blood of a person is saturated with carbon dioxide, the blood supply to all organs is improved, as a result of which a positive effect appears.

The body begins to treat himself from the inside, having a different impact on different groups organs. For example, the improvement of blood supply and the increase in CO2 leads to the normalization of the tone of the smooth muscles of the stomach and intestines. It has a positive effect on the intestinal work, restores its basic functions and helps in the fight against various diseases of the gastrointestinal tract.

Carbon dioxide positively affects the permeability of membranes, which normalizes the excitability of nerve cells. It helps it easier to carry stress, avoid nervous exconctions and, as a result, eliminates insomnia and migraine.

Helps CO2 and with allergies: carbon dioxide reduces the viscosity of the cytoplasm, which fills the cells. This has a positive effect on metabolism and increases the activity of protective systems of the body.

Protective systems and anti-viral diseases are activated. Regular activity of respiratory gymnastics helps to avoid ARVI and ARZ due to the increase in local immunity.

Helps carbon dioxide with bronchitis and asthma: it reduces the spasm of the vessels, which allows you to get rid of sputum and mucus in bronchi, and according to the disease itself.

Due to the normalization of the lumen of the vessels go on amendment and patients with hypotension. Classes of respiratory gymnastics help them gradually cope with low arterial pressure.

Despite all the positive changes arising in our body in normalizing the level of carbon dioxide, it is not a panacea from all diseases. This is more likely to help you have your body by studying breathing gymnastics.

Believe me, after several months of classes, the body will definitely thank you with good well-being. Before you start classes, be sure to check the CO2 level in the body and make sure that the respiratory gymnastics or the Samolader simulator will help with your disease.

And in order not to miss the material about the hypercupinia and receive our new articles on the mail, subscribe to our blog. We will send materials once a week.

Just about 0.04% carbon dioxide is contained in the air. Basically, it enters the air through the decomposition of plant and animal fabrics, as well as in the process of combustion of stone coal and wood.

The content of oxygen and carbon dioxide in the atmosphere of our planet is able to adjust the plants. Under the influence of water and sunlight, carbon dioxide in plant cells turns into starch, as well as in many other nutrients. Plants to live, too, need to breathe. Therefore, they absorb oxygen and excrete carbon dioxide. But in the process of formation of starch, they distinguish much more oxygen than absorb when breathing. But when the starch is formed, vegetable world It absorbs significantly more carbon dioxide than exhausted.

Hence, need to protect the forest and the whole plant world On our planet, because they maintain a constant carbon dioxide and oxygen content in nature.

The benefits and harm of carbon dioxide

Carbon dioxide is very useful for a person, he participates in the intake of oxygen in fabric and regulation human breathing processes.

CO2 greatly affects the climate. Also without it is impossible metabolism. This is an indispensable component for all favorite carbonated drinks.

In turn, he can bring harm. The occurrence of the body with carbon dioxide brings great harm to a person and can cause death.
