principle : Oximetry measurement by noninvasive type infrared technology to measure the fingers, toes, ears, this is the place where the most common measurement of blood oxygen, oxygen content measurement object more accurate term is blood oxygen saturation, namely, SpO2, and the test results in digital form, main show is the ratio of actual full oxygen saturation under oxygen, usually expressed as a percentage, healthy body points of typical oxygen saturation is 90 ~ 100%, but also can lead to lowest 60%. Human blood oxygen saturation depends on many factors, the most important factor is that the patient's blood supply ability is relatively poor, the reading value of HbO2 will decline.
Finger oximeter integrates light sensing technology into the chip. It does not collect human blood samples. Through light sensing penetration, it can monitor the current oxygen content in blood. At the same time, the human pulse rate was measured. Through the pen type LCD display, let the user at a glance, on the fingertip, easily complete two tests. Finger oximeter is suitable for home, hospital, oxygen bar, community medical and sports health care (can be used before and after exercise, not recommended to use during exercise).
