Concept and measurement principle of blood oxygen saturation
In the process of O2 transportation, O2 is mainly combined with hemoglobin in red blood cells, and the amount of physical dissolution is extremely small. In every 100ml of blood, the maximum amount of hemoglobin bound oxygen is called oxygen capacity OCP, and the actual oxygen content of red and white blood is called oxygen content OCN, and blood oxygen saturation is the ratio of the two, namely. In general, the range of SpO2 is 92% ~ 98%. The basic principle of oxygen saturation measurement in vivo is photoelectric method. Arterial blood vessels usually pulsate continuously. During the period of contraction and relaxation, with the increase or decrease of blood flow, the light absorption ratio of contraction and relaxation phase is converted into the measurement value of oxygen saturation, the electronic principle of oxygen saturation measurement
