What Is The Recirculation Of A Central Venous Catheter For Blood Purification? What Is Its Significance For Measurement?

During clinical treatment, part of the purified blood will return to the inlet of the extracorporeal circuit, that is, blood will flow reversely from the venous end to the arterial end, and this part of the purified reverse blood flow constitutes access recirculation. Such vascular access recirculation not only affects dialysis efficacy but also interferes with the assessment of sufficiency of dialysis. The measurement, evaluation, and application of vascular access recirculation can guide clinicians to individualize the prescriptions for different dialysis patients. It also has important significance for guiding the measurement of vascular dysfunction and enhanced dialysis efficacy.
