With the increasing pollution of the social environment, the pace of life of modern people is accelerating, and the consumption of brain and physical strength increases. It is difficult for normal breathing to meet the needs of the human body for oxygen, especially for mental workers, students and drivers. Because the brain is in a state of high tension for a long time, it is extremely difficult It is easy to cause cerebral hypoxia, fatigue, lethargy, unresponsiveness, dizziness, chest tightness, and lack of concentration. In severe cases, it will affect normal life, work and study.
Therefore, oxygen inhalation health care has gradually become popular. Many people have a home oxygen concentrator at home. However, when the oxygen concentration is set, what is the best effect of oxygen inhalation?
The oxygen concentration of the oxygen generator is generally set to 2L~5L. The most common COPD patients need more than 15 hours of oxygen per day, and the oxygen flow needs to be controlled, about 1.5L/min. If the oxygen flow is too high, it will lead to carbon dioxide storage. ,Worse. When doing atomization inhalation, it needs 6-8L/min.
There are five modes of home oxygen generator: oxygen flow 1L concentration 90%, oxygen flow 2L concentration 50%, oxygen flow 3L concentration 40%, oxygen flow 4L concentration 33%, oxygen flow 5L concentration 30%. But it should be noted that:
1. Patients with type II respiratory failure need low-concentration oxygen, which needs to be determined according to the situation.
2. The oxygen generator is generally suitable for patients with long-term hypoxia, such as chronic bronchitis, chronic obstructive pulmonary disease, pulmonary heart disease and other respiratory diseases. Under normal circumstances, when there is no carbon dioxide retention, the oxygen concentration is generally maintained at 2L~3L.
