Fractional oxygen saturation measuring method, involves implementing procedural correction method, which enables display of all saturation parameters such as fractional, functional and dysfunctional hemoglobin saturation

摘要

The method involves implementing a procedural correction method, which enables display of all saturation parameters such as fractional, functional and dysfunctional hemoglobin saturations. The functional saturation is determined under utilization of two wavelengths, and saturation of the dysfunctional hemoglobin saturation is determined under utilization of a set of wavelengths. The saturation of the dysfunctional hemoglobin saturation is calibrated by a correction factor, which is determined from a clinical study. An independent claim is also included for a device for measuring fractional oxygen saturation in blood.
