The process of human metabolism is a biological oxidation process, and the oxygen needed during metabolism enters the blood through the respiratory system. This oxygen combines with the hemoglobin (Hb) in red blood cells to form oxyhemoglobin (HbO₂), which is then transported to various tissues and cells in the body. Generally, SpO₂ is considered normal if it is not lower than 94%, and anything below 94% indicates insufficient oxygen supply. Some researchers set the standard for hypoxemia at SpO₂ < 90% and believe that when SpO₂ is above 70%, the accuracy can reach ±2%, but there may be errors when SpO₂ is below 70%. Clinically, several patients' SpO₂ values have been compared with arterial blood oxygen saturation values, leading to the conclusion that SpO₂ readings can reflect a patient's respiratory function and, to some extent, the changes in arterial blood oxygen.
Blood oxygen monitoring is very important. The current method uses a fingertip photoplethysmographic SpO₂ sensor. When measuring, you only need to place the SpO₂ sensor on the finger. The finger acts as a transparent container holding hemoglobin. Using red light at a wavelength of 660 nm and near-infrared light at 940 nm as the incident light sources, the intensity of light conduction through the tissue bed is measured to calculate hemoglobin concentration and blood oxygen saturation. The patient monitor accessories can then display the body's blood oxygen saturation, providing a continuous, non-invasive blood oxygen measurement tool for clinical use.
