血中酸素飽和度の非接触計測における基礎検討

抄録

The pulse oximeters currently in widespread use measure pulse rate and blood oxygen saturation by contacting the skin surface. Therefore, it can be a burden to users with weak skin. Therefore, we conducted a basic experiment aiming at non-contact measurement of blood oxygen saturation and realized non-contact measurement of pulse wave by measuring light using an XYZ camera. In addition, we investigated whether it was possible to measure oxygen saturation by measuring the tendency of oxygen saturation to change with breath holding. In this paper, we report the results of these two experiments.
