2 Overview
The pulse oxygen saturation is the percentage of HbO
2
in the total Hb in the blood, so-called the O
2
concentration in the blood. It is an important bio-parameter for the respiration. For the purpose of measuring the
SpO
2
more easily and accurately, our company developed the Pulse Oximeter. At the same time, the device can
measure the pulse rate simultaneously.
