The key finding of blood oxygen

已更新:2021年8月19日

[vc_row][vc_column][vc_column_text]The blood oxygen saturation (SpO2) is the percentage of the volume of oxygen-bound oxyhemoglobin (HbO2) in the blood to the total volume of all bound hemoglobin (Hb, hemoglobin), that is, the concentration of blood oxygen in the blood, which is the respiratory cycle Important physiological parameters. The oxygen saturation of normal human arterial blood is above 95% and that of venous blood is 75%.

The metabolic process of the human body is a biological oxidation process, and the oxygen required during the metabolic process enters the human blood through the respiratory system, combines with the hemoglobin (Hb) in the red blood cells of the blood to form oxyhemoglobin (HbO2), and then transported to the human body. Go to some tissue cells. Blood’s ability to carry and transport oxygen is measured by blood oxygen saturation.

Blood oxygen saturation is the newly established indicator for measuring human health in the medical world.

If the body’s blood oxygen content is insufficient, it will cause many complications. The most obvious point is that dizziness is easy to be sleepy, and it is not vigorous and irritable. If the blood oxygen content is insufficient for a long time, the cerebral cortex will first receive the most direct damage. If the brain is damaged, the harm to the human body will be most obvious. There will be a series of serious consequences such as cardiac arrest, myocardial failure, and blood circulation failure.

The 2019 Nobel Prize in Physiology or Medicine, the discovery of three scientists, explains the mechanism of the most important oxygen adaptation process in life, has clarified the mechanism of oxygen sensing, and has shown how it works. They understand for us how oxygen levels affect cells Metabolic and physiological functions laid the foundation.[/vc_column_text][/vc_column][/vc_row]
