  • Method and measuring instrument for measuring the oxygen saturation in the blood
    Patent number: 9320464
    Abstract: The invention relates inter alia to a method for measuring the oxygen saturation of the blood flowing in a peripheral human or animal body part (20), in which electromagnetic radiation (q1?(t), q2?(t)) having a first and a second wavelength is irradiated into the peripheral body part or irradiated through the peripheral body part, the reflected or transmitted radiation (x1?(t), x2?(t)) is measured to form two measurement signals (x1(t), x2(t)), and the oxygen saturation of the blood is determined by evaluating the two measurement signals.
