Descriptions:
Blood oxygen saturation is the percentage of the oxygen-bound oxygenated hemoglobin (HbO 2) capacity in the blood as a percentage of the total bindable hemoglobin (Hb) capacity, that is, the concentration of blood oxygen in the blood, which is an important physiology of the respiratory circulatory system Parameters. Many respiratory diseases can cause the reduction of blood oxygen saturation in human blood. In addition, the body's autoregulatory dysfunction caused by anesthesia, major surgical trauma, and injuries caused by some medical examinations, etc., may cause the patient's Problems with oxygen supply reduce the body's blood oxygen saturation, causing patients to experience symptoms such as dizziness, weakness, and vomiting, and severe cases can be life-threatening. Therefore, timely understanding of the patient's blood oxygen saturation situation can help doctors identify problems in a timely manner. Is of great significance in the clinical medical field.
As long as you insert your finger during the measurement, the display will directly display the measured blood oxygen saturation value, which has high accuracy and repeatability.
