Harm of excess oxygen. Oxygen is a gas closely related to people. Human life is inseparable from oxygen. Animals can't live without oxygen. Without oxygen, it is difficult for a person to survive. Many people will lack oxygen. At this time, they usually have oxygen therapy. What are the hazards of excess oxygen?
Harm of excessive oxygen 1. Severe cases can lead to oxygen poisoning.
The higher the oxygen concentration, the better. If you inhale high concentration oxygen for a long time, you will have symptoms of oxygen poisoning. Cough, chest tightness and chest pain are the main clinical manifestations of oxygen poisoning in the early stage. Some patients with oxygen poisoning will have fundus hemorrhage, and in severe cases, they may be blinded by retinal detachment and posterior lens leukoplakia.
Healthy people who inhale this high flow of oxygen may have headaches and nausea. In addition, too high oxygen concentration may cause some uncomfortable reactions in the airway. Oxygen inhalation is mainly aimed at people with serious respiratory diseases, serious lung diseases and serious heart diseases complicated with cardiac insufficiency. It is suggested that ordinary people should not take oxygen casually to avoid endangering their health.
Oxygen inhalation taboo
1. Healthy people don't need oxygen. The oxygen concentration in the air is 2 1%. When oxygen permeates the alveoli through this concentration, its speed is very fast. Ordinary air is enough for normal people. No problem. It is not very scientific and necessary to buy an oxygen generator for health care.
2, the content of inhaled oxygen, according to the requirements of the doctor, can not be changed without authorization. Inhaling too much or not enough oxygen is harmful to your health.
Harm of excessive oxygen 2 What effect does oxygen have on human body?
Oxygen plays the role of an accelerant in the process of continuous flame combustion, and so does the oxygen in our body. The food we eat, its energy substance glucose has to undergo oxidation reaction with oxygen before it can release energy and be used by our bodies. When a person has no oxygen, then our life will soon disappear.
How does oxygen work in our body
In medicine, the operation of oxygen in human body is divided into three parts: external respiration, gas transportation in blood and internal respiration.
External breathing is an action we are very familiar with. When oxygen is inhaled into the lungs, the blood is loaded with fresh oxygen, which is pumped out by the heart and transported to all parts and cells of the body, so that glucose and oxygen combine to generate energy. The metabolite of glucose and oxygen is carbon dioxide, which is exhaled through the reverse way of blood circulation.
What is anemia and poverty?
Anemia is not the total amount of blood is less, but the hemoglobin cells in the blood are less. Hemoglobin is particularly important. It is the messenger of the whole respiratory movement or oxygen metabolism. One hemoglobin can carry four oxygen and transport it to a single cell in the whole body through our blood circulation system. Without hemoglobin, oxygen cannot be transported to somatic cells, so the human body will be in a state of severe hypoxia and various typical anemia symptoms will appear.
What does oxygen saturation mean?
Oxygen saturation is a simple, effective and intuitive monitoring index to reflect hypoxia in clinic. Simply put, oxygen saturation monitoring is whether hemoglobin is loaded with enough oxygen.
Under normal circumstances, a hemoglobin can carry four oxygen molecules. Under some extreme physiological and pathological conditions caused by some diseases, some hemoglobin can not combine with tetramolecular oxygen, so the blood oxygen saturation drops to a certain extent, and the human body will have symptoms of hypoxia. The highest value of oxygen saturation is 100%. For a healthy person, the general combined amount is 95%- 100%. In plain areas, oxygen saturation below 90% is a very dangerous situation, which is called respiratory failure.
Does it mean that the better your physical fitness, the more you carry?
Every hemoglobin is born with the ability to carry oxygen molecules, and generally has nothing to do with acquired exercise. But in some extreme environments, such as plateau environment, the human body can produce more hemoglobin through compensation.
Does low blood oxygen content represent sub-health of human body?
Under the condition of 2 1% atmospheric oxygen content at sea level, it is impossible to obviously reduce oxygen saturation because hemoglobin has a strong ability to bind oxygen molecules. When dizziness, fatigue, headache and other symptoms appear, it is usually not caused by the decrease of blood oxygen saturation. Because the supply of oxygen carried by the human body far exceeds the need. Generally speaking, the amount of oxygen supplied by arterial blood to the whole body is only about a quarter, that is, three quarters of the oxygen returns to the lungs and acts as a reserve in the body. If the blood oxygen saturation drops, you must find the reason and seek medical advice in time.
Is it necessary to buy a home oxygen generator?
Don't rush to buy an oxygen generator to absorb oxygen by yourself. Oxygen is a medicine, not a health product. Inhale as much as possible. Excessive oxygen enters the body, which is extremely harmful to human tissues and cells. In medicine, the use of oxygen should be based on the treatment needs of diseases and meet the minimum dose needed for treatment.
Can you lack oxygen if you stay in a closed and unventilated room for a long time?
Generally speaking, the house we live in is difficult to be sealed, and there is no air exchange at all. Under the action of atmospheric pressure, the oxygen content inside and outside the house will not change obviously. After staying in a relatively closed environment for a long time, many of us will feel uncomfortable, mainly because the smell in the air is not fresh. In addition, the carbon dioxide exhaled by people in the room can't be discharged outside the house in time, and it is inhaled again by people in the room. This is called repeated breathing. The increase of carbon dioxide content in the body is harmful and even dangerous to the human body. The most common is that the acute increase of carbon dioxide will lead to coma, and people will die after coma, which is called pulmonary encephalopathy in medicine. Pulmonary encephalopathy is not the lack of oxygen in the lungs, but the increase of carbon dioxide.
