With the advent of an aging society, the incidence of chronic diseases is getting higher and higher, which seriously affects human health. COPD is one of the most common chronic diseases.
Chronic obstructive pulmonary disease, short for chronic obstructive pulmonary disease (COPD), is an incompletely reversible chronic obstructive airway inflammatory disease with restricted airflow. It often develops from chronic bronchitis and emphysema. The incidence of chronic obstructive pulmonary disease is high and it is harmful to human health. Although it cannot be completely cured in medicine at present, COPD is a controllable, preventable and curable disease. Most patients can be completely controllable through standardized treatment. The goal. In order to control and prevent the acute exacerbation of chronic obstructive pulmonary disease, in addition to giving corresponding drug control treatment, lung rehabilitation and oxygen therapy are also very important means and measures.
However, because people suffering from COPD are often older and have a relatively rudimentary and inadequate understanding of COPD, it is easy to get into misunderstandings in oxygen therapy for COPD. There are mainly the following seven major misunderstandings:
1. Oxygen inhalation is harmful
This argument is widely spread, including some patients with chronic obstructive pulmonary disease, who believe that oxygen is an external gas that is harmful to the human body and can cause lung damage. And some people have heard or searched the conclusions from the Internet, and even said that there are even theories of oxygen poisoning on the Internet.
2. Oxygen inhalation is prone to addiction
This is the most lethal statement. Some examples are often given to prove that oxygen can become addictive. For example, XX has chronic obstructive pulmonary disease. After absorbing oxygen, it has been inseparable from oxygen, and has become seriously addicted. In fact, there is no literature or data that shows that oxygen can become addictive. The so-called chronic obstructive pulmonary disease that cannot be separated from oxygen is caused by poor lung function, and a considerable part of people are precisely because they did not receive home oxygen therapy in the early stage, which led to a sharp decline in lung function and became dependent on oxygen.
3. No pant, don't breathe
Oxygen inhalation during the acute exacerbation of COPD can partially relieve the symptoms, especially for some patients with hypoxia, this relief effect is obvious. However, the effect of oxygen therapy is not only to relieve symptoms, but to control the acute exacerbation of symptoms and delay the decline of lung function. Therefore, whether it is in the acute exacerbation period or in the stable period, when the partial pressure of arterial oxygen drops to a certain level, it needs to be performed Home oxygen therapy.
4. The higher the oxygen flow rate, the better
Under certain conditions, the higher the oxygen flow rate is, the higher the oxygen concentration will be, and the improvement of hypoxia symptoms will be more obvious. However, too high oxygen flow can lead to high concentration, which is easy to cause oxygen poisoning, especially for patients with type 2 respiratory failure, it is more likely to cause carbon dioxide retention and aggravate respiratory failure, which is a more dangerous situation. Therefore, for patients with chronic obstructive pulmonary obstruction, the oxygen flow must be strictly controlled when inhaling oxygen, generally not exceeding 3L/min, and most of them are set at 2L/min, which means that the oxygen concentration is maintained at about 29%.
5. No need to inhale oxygen during the day
According to the Global Chronic Obstructive Pulmonary Disease Diagnosis and Treatment Strategy (GOLD), the recommended oxygen therapy time is more than 15 hours a day. It is not up to this time limit to use it at night, so oxygen is also required during part of the day to ensure good results.
6. Oxygen inhalation is not as good as medication
For some patients, drugs can significantly relieve their asthma symptoms, but oxygen intake does not improve his asthma symptoms. However, oxygen inhalation is not only suitable for improving symptoms, the most important thing is to protect the decline of lung function and reduce the number of acute exacerbations. The benefits of oxygen therapy are potential.
7. No medication is needed for oxygen inhalation
It is true that some patients can completely control their symptoms by inhaling oxygen, especially for patients who do not have infections. However, COPD itself is a chronic airway inflammatory disease. This non-specific inflammation needs to be controlled by drugs, such as the use of inhaled beta receptor agonists or glucocorticoids. Oxygen cannot control this non-specific inflammation. Inflammation of the opposite sex. In other words, oxygen therapy and medication are two protective methods for COPD, which complement each other and are indispensable.
In summary, standardized treatment of COPD is required. Oxygen therapy is one of the most important contents. It should not be ignored. Treat oxygen therapy properly to allow COPD patients to breathe freely. Our various oxygen concentrators can be suitable for different patients.
