1. Overview The oxygen saturation is the percentage of HbO in the total Hb in the blood, so-called the concentration in the blood, it is an important physiological parameter for the respirato- ry and circulatory system. A number of diseases related to respiratory system may cause the decrease of SpO in the blood, furthermore, some other causes such as the malfunc- tion of human body’s self-adjustment, damages during surgery, and the injuries caused...

is adopted in accordance with Capacity Pulse Scanning & Recording Technology, so that two beams of different wavelength of lights can be focused onto human nail tip through perspective clamp finger-type sensor. Then measured signal can be obtained by a photo- sensitive element, information acquired through which will be shown on screen through treatment in electronic circuits and microprocessor.
