01. Why do some people feel suffocated when using an oxygen concentrator for the first time?

This is because the body has been in a state of hypoxia for a long time, and its functions have adapted to this environment. Suddenly providing high flow oxygen increases the burden on the body, making it difficult for the body to accept for a period of time. Don't be too anxious when using an oxygen concentrator for the first time. You can start by supplying oxygen from low flow rate, as long as the blood oxygen saturation reaches 95%.

02. When is a good time to inhale oxygen?

Half an hour after a meal, the oxygen consumption after a meal will be relatively high because the gastrointestinal peristalsis is intense, the oxygen demand is relatively high, and the blood oxygen supply to the gastrointestinal tract is relatively increased, which will weaken the blood oxygen supply to other organs and increase the cardiac load. So for people with poor heart condition, it is recommended to take appropriate oxygen inhalation half an hour after meals.

Before bedtime, cardiovascular diseases often occur late at night or early in the morning. Taking oxygen before bedtime may reduce the probability of cardiovascular and cerebrovascular diseases; At the same time, oxygen also has a sedative effect. Taking oxygen before bedtime is beneficial for relieving insomnia caused by mental stress or excessive brain fatigue.

03. What is the appropriate time for oxygen inhalation?

The time and target of oxygen inhalation are related to the underlying diseases that require oxygen inhalation, such as when angina occurs, as long as the oxygen inhalation reaches the degree of relief of angina symptoms. But if chronic respiratory failure occurs, the time for oxygen inhalation needs to be relatively extended. For example, when chronic obstructive pulmonary disease occurs with chronic respiratory failure, long-term home oxygen therapy is needed.

If it is a population with chronic cardiovascular and cerebrovascular diseases such as hypertension, coronary heart disease, stroke, cervical spondylosis, etc., oxygen inhalation can be done in stages of early, middle, and late, with each inhalation lasting about one hour; If it is insomnia, oxygen inhalation for 30-60 minutes before bedtime is sufficient; If it is emphysema, pulmonary heart disease, without obvious breathing, heart failure, etc., oxygen can be inhaled for 6 hours per day; But if it is combined with cardiopulmonary dysfunction and secondary erythrocytosis, the oxygen uptake time can be extended to 10-15 hours per day.

04. Precautions during oxygen inhalation?

1. The oxygen concentrator should be placed flat and stable, otherwise it will increase the operating noise of the oxygen concentrator;

2. Choose the appropriate oxygen intake and duration based on the advice of a doctor or professional:

3. Pay attention to ensuring that there are no heat sources or light or dark sources of fire around the oxygen concentrator. If you need to check for oxygen emissions, please use a professional oxygen meter for testing;

4. After using the oxygen concentrator for a period of time, the filter screen will become very dirty. Therefore, we need to clean the filter screen regularly to extend the service life of the oxygen concentrator and allow us to breathe fresher oxygen.
