The investigators speculated that the shorter response time with the reflectance forehead probe was most likely due to the location ...
WebThe device passes two wavelengths of light through the body part to a photodetector. It measures the changing absorbance at each of the wavelengths, allowing it to determine the absorbances due to the pulsing arterial blood alone, excluding venous blood, skin, bone, muscle, fat, and, in most cases, nail polish.
