Abstract (en)

[origin: WO9817193A1] Access recirculation in a shunt is determined quantitatively by a method in which a standard solution, such as saline, is injected into a patient's (200) bloodstream upstream of the shunt. At a point in the access line, a photometric measurement is conducted of the change in hematocrit (delta H) with respect to time. Electronic circuitry (150) receives signals from the detector (100), compares the integrated area of delta H with respect to time of the standard solution initially flowing through the access of the recirculated solution, and provides display of recirculation (152).
