Detection principle

Oxygen is the basis for sustaining human life. The contraction and relaxation of the heart causes the blood of the body to pulsate through the lungs. A certain amount of reduced hemoglobin (HbR) combines with the oxygen in the lung to form oxygen and hemoglobin (HbO2). About 2% of oxygen is dissolved in plasma. This blood is transported through the arteries to the capillaries, which release oxygen in the capillaries to maintain the metabolism of the tissue cells. Oxygen saturation (SpO2) is the percentage of oxygen-bound oxygenated hemoglobin (HbO2) in the blood to the total binding hemoglobin (Hb) capacity, which is the concentration of blood oxygen in the blood. It is an important physiology of the respiratory cycle. parameter. Functional oxygen saturation is the ratio of HbO2 concentration to HbO2Hb concentration, which is different from the percentage of oxygenated hemoglobin. Therefore, the monitoring of arterial oxygen saturation (SaO2) can estimate the lung oxygenation and hemoglobin oxygen carrying capacity.
