Pulse Oximetry (PO) is considered to be the most critical health indicator ranked at position 5, in addition to heart rate, blood pressure, respiratory rate and temperature. Hemoglobin (Hb) is an important component of blood cells, which is responsible for the transport of oxygen from the lungs to other tissues of the body. The amount of oxygen that hemoglobin contains at any one time is called oxygen saturation. Oxygen saturation is expressed as a percentage, which is the ratio of the oxygen content of hemoglobin to the oxygen carrying capacity of hemoglobin. The blood oxygen saturation is an important physiological parameter for reflecting whether the respiratory function and the oxygen content of a human body are normal or not, and is an important physiological parameter for displaying whether each tissue of the human body is healthy or not.
