ABSTRACT:
A spectrophotometric method and device are described which are particularly useful for on-line monitoring and control of blood parameters. Determination of a blood parameter without measuring or directly following another blood parameter, is made possible by using information contained in scatter and at least three distinct detection locations. Calibration using means for scattering a light beam to a suitable reference geometry, is beneficially used. Constant values related to the detection locations are derived. Later, these constants may be used to determine a blood parameter. Two different wavelengths and at least for detectors may be used. The device is beneficially applied to extracorporeal circuits, and may be used to optimize dialysis.
