In order to meet the oxygen inhalation needs of different groups of people, the current general household oxygen concentrators are 1-5L adjustable. However, many users still have misunderstandings in use. They feel that the longer the oxygen inhalation time and the higher the oxygen concentration, the better. The following is to introduce how to grasp the oxygen concentration of oxygen therapy for your reference:

1. Oxygen inhalation concentration of office workers and students

Office workers and students should inhale 50% oxygen concentration when inhaling oxygen. Oxygen inhalation for office workers can supplement the oxygen needed by the brain, eliminate fatigue, refresh the mind, and improve sleep; oxygen supplementation for students can relieve brain fatigue and improve learning efficiency.

2. The oxygen concentration of pregnant women and the elderly

Pregnant women and healthy elderly people should ensure 60%-80% oxygen concentration when inhaling oxygen. The oxygen demand of pregnant women is twice that of normal people. Oxygen inhalation of pregnant women can promote fetal growth and improve immunity of pregnant women; oxygen inhalation of elderly people can prolong life, enhance immunity and improve sleep.

3. The oxygen concentration of the patient population

The patient population requires an oxygen concentration of 90% or more depending on the condition. When using an oxygen concentrator, the patient population must inhale oxygen according to the doctor's instructions. Oxygen inhalation for patients can enhance the absorption of medicines, improve the condition, and help the body recover.

The above is an introduction to how to grasp the concentration of oxygen therapy. It is hoped that the majority of users will choose the appropriate concentration and flow rate when inhaling oxygen, so as to achieve the best oxygen therapy effect.
