Method of setting the blood flow through the bloodstream of a live being and device for an indicator application

摘要

Blood flow rate in the bloodstream of a live being is measured using glucose as an indicator continuously supplied to the bloodstream. A reference sample is taken in a selected of measured segment of the bloodstream and then, an indicator of known concentration and known flow is added to the bloodstream, while—with a time delay—there is performed the taking of at least one blood sample from a measuring point, located downstream, while the resulting flow rate through the measured segment is set on the basis of a functional relationship.

1. A method of estimating a blood flow in a bloodstream in a live being body using glucose as an indicator continuously supplied to the bloodstream, the method comprising:
taking a reference sample in a selected location of a measured segment of the bloodstream; thereafter, adding an indicator of known concentration (Gi) and known flow (q) to the bloodstream; after some time interval, taking at least one blood sample from a downstream measuring location; and arriving at an estimate of the resulting flow through the measured segment according to the following formulaQ=q(Gi-Gs)(Gs-Gk)
