How to know the suitable oxygen flow?

The importance of oxygen absorption flow is even more important than the quality of oxygen generator that people generally care about. Before, I explained the relationship between oxygen flow and oxygen concentration in detail in the article "Control of oxygen inhalation flow and oxygen inhalation time". To sum up, the flow rate is inversely proportional to the concentration. As long as one aspect is determined, the other is fixed. The oxygen flow required by different groups of people will also have specific differences. Let me talk about what is the appropriate oxygen flow: 1. Principle: If conditions permit, it is best to consult a doctor before inhaling oxygen. That would be more professional and comprehensive. 2. Essence: People often ask me "How much concentration should I inhale" and "My grandmother has emphysema, how much flow should I inhale?" Wait, I said here, in fact, the oxygen flow is not fixed, but elastic. According to the different situations of people, the time of oxygen inhalation is constantly adjusted, and the flow rate is effective. We can try our best to use it, but we can't stay the same. 3. Methods: The optimal oxygen flow rate can be determined by observing the degree of symptom relief before and after oxygen inhalation, and the lowest oxygen flow rate with obvious symptom relief can be regarded as the conventional oxygen flow rate. When the condition changes and the symptoms are alleviated or aggravated, the oxygen inhalation flow should be adjusted accordingly. 4. General situation: ① The oxygen inhalation flow rate of patients with respiratory diseases should not be too large, and it is generally controlled at 1-2L. ② The oxygen intake flow of other oxygen therapy health care people is generally 2-3L. To sum up, I think official website Bianxiao's question about oxygen production is very clear, and there should be no problem. I hope you can read this article carefully. Official website ripple caused by oxygen is something that has been summed up after careful consideration.
