Reflective oximetry

WebReflectance pulse oximeters are placed on the skin surface and measure the light reflected off the tissues rather than through the tissue. In this way, absorption is measured to calculate oxygen saturation. Of note, reflectance devices are inherently more difficult to design to perform well. References: Lifebox Pulse Oximetry Learning Module Web1.1 Reflectometry and Ellipsometry. Reflectometry deals with the ratio of reflected to incident intensities Io / Ii =∣ r ∣ 2 = R, where R is the (power) reflectance, and where, for the …
