It seems that oxygen supplementation is very popular now, but I would like to ask if oxygen is addic

It is very safe to use a regular oxygen inhaler to inhale oxygen for health care.

1. Will oxygen inhalation be poisonous?

So-called "oxygen poisoning" is the inhalation of high concentrations of oxygen (concentration 7o) under a closed respirator mask for more than 24 hours; or in a hyperbaric environment, oxygen poisoning may occur for more than 5 hours.

At present, medically reported cases of "oxygen poisoning" are mainly premature infants. Premature infants need to be monitored in an incubator and given an oxygen-rich environment to help improve the symptoms of hypoxia caused by poor tissue development. If the nursing method is improper, the oxygen concentration in the box is too high, and the continuous oxygen administration time is too long, it may lead to extensive vascular blockage and hyperplasia of the baby's retina, retinal detachment, atrophy, etc., resulting in the serious consequences of lifelong blindness of the baby.

In addition, it has been reported that "pulmonary oxygen poisoning" may occur when diving or hyperbaric oxygen ** severe decompression sickness, and long-term inhalation of hyperbaric oxygen may occur, with symptoms similar to bronchopneumonia, and severe lung lesions similar to lobar pneumonia may occur. Conventional oxygen inhalation, aerobic poisoning has not been reported at home and abroad. Oxygen masks, nasal cannulas, or open oxygen are commonly used, and oxygen toxicity is unlikely to occur even if pure oxygen is given.

Human survival is inseparable from oxygen, has been constantly ingesting oxygen throughout life, the role of reasonable oxygen supplementation is to increase the oxygen content of arterial blood, improve the hypoxia of the human body, restore and promote the virtuous cycle of metabolic processes, and never change the natural physiological state and biochemical environment of the body, but also do not change the biochemical and physiological state of the central nervous system, unlike drugs sleeping pills and other drug dependence. People who are on oxygen care will not have any "withdrawal syndrome" and will not feel unwell. However, some of the symptoms of hypoxia that were previously relieved or improved by supplemental oxygen supplementation may recur due to the cessation of supplementation, which only means that your body is deprived of oxygen due to various factors, which may cause permanent damage over time, leading to more serious conditions, and it is extremely necessary to adhere to daily oxygen care or home oxygen therapy.

2. Is oxygen addictive?

No. Human survival is inseparable from oxygen, has been constantly ingesting oxygen throughout life, the role of reasonable oxygen supplementation is to increase the oxygen content of arterial blood, improve the hypoxia of the human body, restore and promote the virtuous cycle of metabolic processes, and never change the natural physiological state and biochemical environment of the body, but also do not change the biochemical and physiological state of the central nervous system, unlike drugs sleeping pills and other drug dependence.

Oxygen is not addictive.

Oxygen, as the material basis of human metabolism, once it is lacking, it will inevitably lead to abnormal metabolism of the human body and various pathological reactions; At the same time, oxygen therapy, as a very widely used means of modern medicine, is mainly effective in correcting the body's hypoxic state caused by various external or internal factors, so as to achieve the purpose of the disease. If the factors of hypoxia in the human body disappear, you can not deliberately inhale oxygen, and there will be no adverse reactions to the body in such a state. However, the problem is that many diseases of the human body, such as emphysema, pulmonary heart disease, cerebral congestion, etc., are irreversible, and the hypoxic state of the body caused by them cannot be changed, so it is necessary to insist on oxygen therapy for a long time, but this absolutely does not mean that the human body will be addicted to oxygen.

If you have that time, you might as well go outside and breathe!

Yes, it's very comfortable when you suck, and when you wash it, you don't feel anything special, if you smoke it often, you feel something less when you don't smoke.

Healthy people should not inhale oxygen with too high concentration in plain areas; If long-term oxygen inhalation will be hypoxic in the usual environment, which is not good for the body, such as chronic bronchial diseases, people with asthma can inhale oxygen at intervals;

It's better to have time to play in the wilderness than anything else, and that air is pure and natural.

It's better to do more aerobic exercise.

It's better not to use those things all the time

If you are a patient with coronary heart disease, pulmonary heart disease, asthma, bronchitis and various cardiovascular and cerebrovascular chronic diseases, pregnant women, mental workers with intense work and study, junior and high school exam preparation students, residents of plateau hypoxic areas, and tourists, as long as you have a bright brand oxygen machine, you can make your work, study and life infinitely better.

Oxygen health care improves sub-health status.

Scientists, entrepreneurs, and government officials use their brains excessively to cause brain fatigue; Middle-aged and elderly people prevent disease and anti-aging, enhance eyesight, improve aging eyes, improve the ability to be exempt from military service, and enhance physical fitness; The oxygen consumption of the human brain accounts for a quarter of the oxygen consumption of the whole body during the examination period, due to the academic tension, it is very easy to cause brain fatigue, make the thinking sluggish, affect intelligence and memory, oxygen inhalation can significantly improve the above symptoms, improve academic performance; Pregnant women with perinatal perinatal diseases and fetal distress, pregnant women can inhale oxygen to make the fetus develop better. Prevent preterm birth or neonatal dementia.

Diseases of the cardiovascular system.

Coronary heart disease, myocarditis, rheumatic heart disease, myocardial infarction, atherosclerosis, heart failure, hypertension and other diseases.

Diseases of the respiratory system.

Occupational diseases such as tracheitis, bronchitis, asthma, emphysema, poor lung function, pneumonia, lung cancer and cor pulmonale; Oxygen for half an hour before going to bed helps improve sleep quality.

1. Increased oxygen consumption in people.

Pregnant women who mainly need oxygen to give to the fetus; athletes with hyperoxygen consumption after exercise; Mental workers who use their brains excessively, including intellectuals, bosses, managers, and students taking exams; urbanites with a hectic pace of life; Drivers who drive long distances, etc.

2. People who have insufficient ability to utilize oxygen.

Including patients with respiratory tract (nasal allergy, asthma, chronic bronchia), cardiovascular (hypertension, coronary heart disease), cerebrovascular (stroke), blood diseases (anemia, etc.), the elderly (diabetes, etc.).

3. Urbanites with insufficient oxygen supply in their working and living environments.

Studies by medical experts have shown; 90% of urbanites lack oxygen. This is mainly due to increasing industrial pollution and soaring vehicle emissions, as well as the reduction of urban green spaces, which makes it easy to find less and less oxygen in the air. On the other hand, urban people work for a long time and live in air-conditioned rooms and offices with closed doors and windows, and indoor polluted air is recycled, and the oxygen content of the air is getting less and less.

According to the measurement, the oxygen content in the high-rise office of the big city is 18% (21% normal), which is the same as the hypoxia alarm point in the coal mine.

4. Oxygen health care for the elderly.

Aging is a natural process and is not necessarily accompanied by diseases, but the decline of physiological regulatory function and immune function in the elderly inevitably increases the possibility of disease. It is often difficult to distinguish between physiological pathogenic and pathological changes in the elderly, but they coexist and influence each other, forming a series of complex changes. Through oxygen inhalation, the elderly can directly make up for the deficit of essential oxygen due to the decline of physiological function through oxygen inhalation, regular and timely supplemental oxygen intake, so as to maintain the normal function of various organs of the body, prevent various geriatric diseases caused by hypoxia, maintain physical and mental health, and delay the aging process.

Is the oxygen bar really reliable? Who needs oxygen? Is too much oxygen harmful to the body?

1. According to two large-scale clinical studies done in the United States and Europe in the 60s, long-term home oxygen therapy can indeed prolong the survival of some patients. However, there are indications for these patients, and the indications are clearly written in the textbook. In our country, due to the problem of physician level or some economic interests, more patients use oxygen concentrators, but many are not enough to meet the indications, and blood gas analysis must be performed during remission to determine whether long-term home oxygen therapy (LTOT) is needed.

If the physician prescribes the correct order, the patient should be severely obstructed, but this does not mean that the patient meets the indications for LTOT.

2. The oxygen concentration of 5l min oxygen and 1l min oxygen you mentioned, I estimate that it is the oxygen concentration provided by the oxygen concentrator provided in the oxygen concentrator manual. However, many people misunderstand this oxygen concentration and think that it is the oxygen concentration of the inhaled gas. These two are completely different.

Part of the inhaled gas comes from the oxygen concentrator and part of the gas comes from the air. The true inhaled gas concentration is achieved when the two are mixed.

Some people take out the formula in the textbook Inhalation gas oxygen concentration = 21 + oxygen flow rate * 4, it should be noted that this formula is a simple and well-known formula, and it is conditional to be established. First of all, this is for medical oxygen, which is basically a pure oxygen source, rather than an oxygen generator that changes the oxygen concentration with different flows. Secondly, this formula assumes that the patient has a certain tidal volume, inspiration-exhalation ratio, bilateral nasal patency, etc.

Formulas are of little value to the questioner.

3. Oxygen poisoning requires long-term inhalation of more than 50% of oxygen, for the questioner, it is absolutely impossible for the oxygen generator to produce more than 50% of the inhaled oxygen, I have previously estimated that it takes about 10l min for pure oxygen to be the oxygen source to produce 50% of the inhaled oxygen concentration.

Officially your question:

If your doctor is not wrong and this patient should be on long-term home oxygen therapy, then you only need pulse oximetry monitoring, as long as the oxygen saturation is just over 90%, this oxygen flow is appropriate.

Not enough, most individuals do not have the equipment here, then, you can measure it in the hospital, and then estimate the flow at home.

In fact, it really doesn't have to be so accurate at all, life is not about doing scientific research.

You just make the patient feel comfortable, generally speaking, it's okay to be bigger, anyway, the oxygen concentrator you said won't cause oxygen poisoning. (Think about it, if you can be poisoned by oxygen and start a lawsuit, the manufacturer will not pay for death).

However, it is too large for the patient to be comfortable, such as a dry nose. So, it's okay to be comfortable.

If it is not a special case, it is best not to use an oxygen concentrator to sleep. Only people who are hypoxic need oxygen. If you are doing oxygen therapy at home, you also have to look at the two indicators of blood oxygen partial pressure and blood oxygen saturation.

Only people with a partial pressure of oxygen below 60 mm Hg or an oxygen saturation below 90% require additional oxygen. If there is no lack of oxygen, there is no need for oxygen at all.

If you inhale oxygen blindly, there will be ***. If a healthy person inhales oxygen in a short period of time, it will cause oxygen poisoning, which is manifested as a burning sensation behind the sternum, dry cough, nausea and vomiting, irritability, dyspnea and other symptoms. High oxygen concentrations can lead to lung tissue damage, and oxygen masks or oxygen tubes that are not properly sterilized can also lead to an increased risk of respiratory infection.

If you want to take oxygen, you must do a test of blood oxygen partial pressure and blood oxygen saturation in advance.

Oxygen concentrators have a certain effect on people with hypoxia, such as chronic obstructive pulmonary disease, asthma, bronchiectasis, gas poisoning and other diseases, and oxygen therapy is needed to relieve symptoms when patients have hypoxemia. Home oxygen therapy can indeed change the course of COPD, but it must be in line with the indications and under the guidance of a doctor.

The oxygen saturation of normal human arterial blood is 98%, and venous blood is 75%.

It is generally believed that the normal SPO2 should not be less than 94%, and below 94% is insufficient oxygen supply. Some scholars have set 90% SPO2 < as the standard for hypoxemia, and believe that the accuracy can reach 2% when SPO2 is higher than 70%, and there can be error when SPO2 is less than 70%.

The metabolic process of the human body is a biological oxidation process, and the oxygen required in the metabolic process enters the human blood through the respiratory system, combines with the hemoglobin (HB2) in the red blood cells to form oxyhemoglobin (HBO2), and then transports it to all parts of the human body. The ability of blood to carry and transport oxygen is measured by oxygen saturation.

At present, medical oxygen is mainly transported to hospitals by special oxygen stations, and some large hospitals also have their own oxygen stations. If the home is oxygenated, you can go directly to the oxygen station or to the hospital. Oxygen stations are high-risk working environments and are generally located in very remote locations that are not easy to find.

If medical oxygen is needed, it is recommended to go to the hospital to refill it. This service is usually provided in the emergency department of each hospital, but some large hospitals only provide tubed oxygen, which is difficult to fill, so it is recommended to go to a first-level hospital for oxygenation.

First, the benefits of oxygen inhalation can reduce angina pectoris and prevent myocardial infarction. Acute myocardial hypoxia can lead to angina, and persistent myocardial hypoxia for more than 30 minutes can cause myocardial infarction, which is a major risk factor for death. Oxygen inhalation at the time of disease attack or regular health care can prevent or reduce the occurrence of angina pectoris and myocardial infarction, and buy time for the disease.

2.Oxygen prophylaxis prevents mortal coronary artery disease:

Because the onset is special but unpreventable, there are often persistent mild brain tightness, shortness of breath, abnormal mood or arrhythmia before the onset of the disease.

3.Oxygen inhalation** Asthma has significant efficacy:

Asthma is caused by the weakening of the exchange function between the alveoli and the outside world due to bronchitis, bronchospasm and other reasons, and oxygen inhalation can increase the oxygen concentration in the alveoli and help relieve asthma.

Fourth, oxygen inhalation can effectively ** emphysema, cor pulmonale, chronic bronchitis: all cases are caused by severe hypoxia, oxygen inhalation can alleviate the symptoms of hypoxia in patients, significantly increase blood oxygen saturation, and have a significant effect than drugs alone.

5.Oxygen inhalation has an adjuvant effect on diabetic patients

Studies have shown that diabetes is associated with a lack of oxygen in the body. The capillary pressure of diabetic patients is significantly low, resulting in insufficient oxygen in tissue cells, resulting in cell dysfunction and glucose metabolism disorders. Therefore, oxygen therapy for diabetic patients is becoming more and more important in the medical community.

6.Oxygen inhalation has a health care effect on healthy people:

Due to the serious effect of air pollution, air conditioners are commonly used and regularly inhaled oxygen can clean the respiratory system, improve organ function, enhance the overall immunity of the human body, and prevent a variety of diseases.
