How much is the normal range of human blood oxygen?

summary

People live on oxygen. After oxygen is inhaled from the lungs, oxygen enters the blood through capillaries and is transmitted to various organs or cells of the body for use. The higher the oxygen content in the blood, the better the metabolism. How much is the normal range of human blood oxygen? Let's talk about it

How much is the normal range of human blood oxygen?

People are generated by oxygen. After oxygen is inhaled from the lungs, it enters the blood through capillaries. Blood is delivered to various parts and organs of the body. If the blood oxygen concentration is too high, the metabolism of the human body will be better. Of course, too high blood oxygen content is not a good phenomenon. There is a certain amount of blood oxygen in the human body. If it is too low, it will lead to insufficient oxygen supply and cell aging. Therefore, too high or too low is not a good phenomenon. Only when the blood oxygen concentration is in the normal range can it be healthy. Generally, the normal range of the human body is about 95%. However, there is no way to judge the blood oxygen concentration of the young and the elderly by one standard.

Blood oxygen saturation refers to the percentage of hemoglobin and oxygen saturation, so blood oxygen saturation and normal concentration range of blood oxygen are normal reactions of human health. Normal arterial oxygen saturation is about 95% to 97%, and mixed venous oxygen saturation is 75%, which indicates that there are differences in blood oxygen saturation under different conditions, However, in medicine, there is a certain range for this gap. As long as you are in this healthy condition, you will not be affected. Therefore, we should understand the normal range of blood oxygen saturation and distinguish its importance.

We all know the normal range of blood oxygen saturation. After the occurrence of diseases in the body, many patients need to regularly detect the blood oxygen saturation. Only after we have a clear understanding of the blood oxygen saturation can we know the patient's current physical condition. If there is a lack of oxygen in the patient's blood and the content is too much, the impact on the health of the disease is very serious.

matters needing attention

For people aged 10-18, they should sleep 8 hours a day; People aged 18-50 should get 7 hours of sleep a day; 50-70 years old, sleep 5-6 hours a day is enough. For the elderly, the quality of sleep will decline, so you can't rule out how long you have to sleep every day.
