What problems will occur when the human body is deprived of oxygen? Let's take a look!

Insufficient oxygen can cause changes in the body that cannot be metabolized properly. In an oxygen-deficient environment, the central nervous system of the human body.

Cardiovascular, respiratory, liver, kidneys, tissue cells, etc. are all affected, and long-term living in a hypoxic environment will cause irreparable damage to brain tissue, for example, mountaineers will have fatigue, indifferent expression, drowsiness, incoherent speech and other mental symptoms due to lack of oxygen, which is the possibility of hypoxia.

When the human body is deprived of oxygen, it affects the central nervous system. Dizziness and headache occur.

Symptoms such as weakness, unresponsiveness, fatigue, and drowsiness. Affect the respiratory system, and symptoms such as chest discomfort, difficulty breathing, itchy throat, and cough appear. Affects the circulatory system, palpitations appear.

Symptoms such as a rapid or slowed heartbeat. Affects the digestive system.

Symptoms such as appetite, complacency, and constipation occur. At the same time, mouth sores.

Pharyngitis, bleeding gums, dandruff, pallor, wounds that do not heal easily, etc. can also be alarms from the body when there is a lack of oxygen. Long-term hypoxia leads to decreased immunity and susceptibility to colds.

After the body is deprived of oxygen, it will lead to dizziness in the body, and the heart can supply blood to all organs of the body, especially the amount of blood transported by the brain accounts for 15% of the total, and the oxygen consumption of the brain accounts for 23% of the human body, far exceeding the average level. If oxygen is not supplied to the brain parts in a timely manner, the functioning of the brain will be affected, and mild people will become dizzy, and over time, memory will also decline. I haven't done much physical work in the recent period and have plenty of rest time, but I still have physical fatigue and weakness in my limbs during the day, which means that my body is deprived of oxygen.

When you are in a state of hypoxia, the various organs in the body cannot function normally, which can cause fatigue. When it comes to the symptoms of edema, some people simply think of decreased kidney function or drinking too much water, but it is not well understood that edema can also be a sign of hypoxia. This is because the cells are hypoxic after electrolytes.

If the sodium ion increases, the excess water will enter the cell, so it will first cause cell edema, and then compress the surrounding microvessels, resulting in poor microvascular circulation.

Due to the lack of oxygen supply to multiple organs in the body, some diseases of the lungs occur at this time, due to long-term hypoxia, it will cause degeneration of the lungs, and the lung tissue will be damaged to varying degrees, such as the expansion of the lungs, and the fibrosis and calcification of the lung tissue to different degrees, resulting in bronchial asthma.

It will cause various organs to be very uncomfortable, there will be chest tightness, dizziness, weakness of limbs, and tinnitus.

There will be shortness of breath, which is likely to cause suffocation, and you will also feel sick to your stomach, foaming at the mouth, and nausea.

One is that the oxygen supply is insufficient, and the other is that there is a barrier to the use of oxygen. Therefore, hypoxia is mainly caused by the following reasons:

1. Insufficient oxygen inhaled, including insufficient oxygen concentration inhaled, such as insufficient oxygen inhaled per unit time due to people in a high-salt environment or lung diseases. For example, there is chronic obstructive pulmonary disease, asthma, etc., or there is respiratory muscle paralysis, thoracic deformity, etc.

2. There is not enough oxygen available in the blood. These include a decrease in the amount of hemoglobin leading to an inadequate ability to transport oxygen, as well as a decrease in the ability of hemoglobin to transport oxygen, common causes of anemia and carbon monoxide poisoning.

3. The amount of tissue oxygen ** is reduced. Common causes include decreased cardiac output due to cardiac insufficiency, and decreased oxygen transport to tissues and organs per unit of time.

4. Tissue or cell oxygen utilization disorder, common hydride poisoning leads to tissue oxygen utilization disorder.

People who are heavy on mental work.

People with heavy brain power will excite the sympathetic nervous system when they use their brains for a long time, excessive stress, excessive tension or anxiety, which will make a large amount of adrenaline secreted, enhance metabolic ability, increase oxygen consumption, and when the inhaled oxygen cannot meet the demand, it will make the brain lack oxygen. In addition, prolonged lack of exercise, long-term stay in a confined environment, poor cardiorespiratory capacity, and excessive reliance on electronic devices can cause the body to lack oxygen. In addition, cerebral infarction, trauma to the brain, and chronic obstructive pulmonary disease (COPD) can prevent the lungs from supplying oxygen, resulting in pathological hypoxia.

Prolonged lack of exercise, prolonged stay in a confined environment, poor cardiorespiratory capacity, and excessive reliance on electronic devices can deprive the body of oxygen. People with heavy brain power use the brain for a long time, excessive pressure, excessive tension or anxiety, etc., will excite the sympathetic nerve, make a large amount of adrenaline secretion, enhance metabolic ability, increase oxygen consumption, inhaled oxygen can not meet the demand, it will make the brain lack of oxygen.

Don't underestimate the lack of oxygen to the brain. Long-term cerebral hypoxia can cause irreversible damage and even brain death. In general, "lack of oxygen in the body", even if there is no direct danger to life, can cause damage to health.

Oxygen, like food and water, is the key substance of human metabolism and the first need for life movement, and nutrients must be oxidized to produce and release chemical energy. Hypoxia refers to hypoxia and is a general term for hypoxia or hypoxia in the air. Nature provides basic living conditions for everyone.

But if you are in a special environment with a lack of oxygen, or if there is no lack of oxygen in the environment, and you can't take in enough oxygen for your own reasons, or you can't make full use of the oxygen you inhale, the human body will change in function, metabolism and morphology. The general term for this state is hypoxia or hypoxia. Therefore, physicians divide the causes of hypoxia into environmental hypoxia, pathological hypoxia, physiological hypoxia, and exercise hypoxia.

General manifestations of hypoxia: the general manifestations of hypoxia are dizziness, headache, tinnitus, dizziness, weakness of limbs, followed by nausea and vomiting, shallow breathing, fast, weak, fast heartbeat, weak.

With the aggravation of hypoxia, confusion will gradually appear, the whole body**, lips, nails will be blue, blood pressure will drop, pupils will be dilated, coma, and finally death due to dyspnea, cardiac arrest, hypoxia suffocation. Normal oxygen metabolism begins with ventilation and gas exchange in the respiratory system. Disturbances in any part of the breathing process can lead to insufficient gas exchange.

At this point, the body responds first with a compensatory protective response. Due to the direct action of nerve reflexes or blood gases, the depth of breathing can be increased, which in turn increases the respiratory rate.

If the compensatory response does not meet the body's needs, hypoxia occurs. As a result, the partial pressure of oxygen in the arteries is lower than normal, and the partial pressure of carbon dioxide due to carbon dioxide accumulation is higher than normal. This phenomenon is always referred to as respiratory insufficiency.

A partial pressure of oxygen in the arteries below 60 mmHg, or a partial pressure of carbon dioxide above 50 rnmHg, is called respiratory failure. The harm of hypoxia: No matter what causes hypoxia, it can change the body's function and metabolic state. The nervous system is most sensitive to hypoxia.

Even mild hypoxia can lead to mental and visual dysfunction.

Dyspnea, redness, syncope, are the most common external manifestations of people when they are hypoxic, oxygen is a necessary condition for human life, if hypoxia will lead to many problems, serious may affect life, and oxygen will also affect the body's blood microcirculation and many aspects, it is recommended that you can try O2ARK's hyperbaric oxygen chamber, which can be a good supplement for the human body and improve Accelerate understanding.

When people lack oxygen, they will have purple lips, cyanotic complexion, dark nails, dark blue, and dilated pupils, so oxygen is indispensable for human beings.

When people are hypoxic, they will be more anxious and restless, the heart rate will increase, and the blood pressure will continue to increase; Manifestations such as a decrease in the level of activity and consciousness of the human body.

The first point is that when there is a lack of oxygen, there will be dizziness, which should also be paid attention to, the second point will be particularly fatigued in the head and body, and the third point will be particularly weak, which should be noted.

1.Pulmonary fibrosis leads to hypoxia, which is cyanosis of the nail beds of the lips or extremities, or the fingers called clubbing like a small hammer; 2.The main reason for their formation is the increase in the reduction of hemoglobin in the human body, hemoglobin is oxygen-bearing, which will contain oxygen, but if the body is hypoxic, there will be deoxygenated hemoglobin, also called reduced hemoglobin, because there is no oxygen, so it is purple.

1. Effect on the central nervous system The tolerance of each part of the brain tissue to hypoxia varies, with the cerebral cortex having the worst tolerance and the brainstem having the strongest tolerance. At body temperature37, the oxygen supply stops circulating for a few minutes, and the brain tissue can be irreversibly damaged. Patients with moderate hypoxia may have psychiatric symptoms such as fatigue, apathy, lethargy, euphoria, and incoherent speech.

Aggravation of hypoxia can cause blurred vision, and even cerebral edema, increased intracranial pressure, coma, and brain cell death.

2. Impact on cardiovascular myocardium is one of the organs sensitive to hypoxia. Mild to moderate hypoxia can increase heart rate and blood pressure; Aggravation of hypoxia can lead to decreased myocardial contractility, slowed heart rate, decreased blood pressure, decreased cardiac output, and even caused arrhythmia and cardiac arrest.

3. Effect on respiration Long-term hypoxia causes tissue vasoconstriction and increased pulmonary artery pressure, resulting in right ventricular hypertrophy and pulmonary heart disease.

4.Effect on liver and kidney Acute hypoxia causes hepatocyte edema, degeneration and necrosis, which causes renal vasoconstriction, renal blood flow decreases, renal tubular epithelial cells are turbid, watery degeneration and even necrosis, resulting in renal insufficiency.

5.Effect on histiocytes Anaerobic glycolysis is enhanced in hypoxia, and large amounts of lactate, ketone bodies, and inorganic phosphorus accumulate to cause metabolic acidosis, causing intracellular edema and extracellular hyperkalemia.

Are hypoxic agents harmful to the human body.

Prolonged lack of oxygen to the brain can cause irreversible damage and even brain death. General "lack of oxygen in the body" can cause damage to physical health, even if it does not directly threaten life.

Oxygen, like food and water, is the key substance of the body's metabolic activities, is the first need for life movement, nutrients must be oxidized, in order to produce and release chemical energy. Cells undergo glycolysis under hypoxic conditions, which produces much lower energy than normal, and at the same time produces lactic acid waste, which accumulates to form an acidic constitution, which can cause chronic diseases and even cancer in the long term.

Hypoxia refers to oxygen deficiency, which is a general term for the state of hypoxia or oxygen deficiency in the air. Nature provides basic living conditions for everyone, however, if we are in a special environment where there is a lack of oxygen, or although there is no lack of oxygen in the environment, we cannot take in enough oxygen due to our own reasons, or we cannot make full use of the oxygen we inhale, the human body will undergo functional, metabolic and morphological changes. Therefore, medical scientists divide the causes of hypoxia into environmental hypoxia, pathological hypoxia, physiological hypoxia and exercise hypoxia.

Under what circumstances the human body is deprived of oxygen.
