receiver. As these lights pass through the finger, a proportion of the light is absorbed
by the blood and by the soft tissue, in function of the concentration of heamoglobin.
The quantity of light absorbed, at each frequency, depends on the degree of
oxygenation of the haemoglobin inside the soft tissue.
This measurement principal ensures accuracy and reproducibility, without requiring
regular calibration.
The oximetry sensor can be disinfected with isopropilic alcohol.
