Continuous measurement of vascular access recirculation by conductivity

Vascular access recirculation is one of the main factors influencing dialysis efficiency. The underestimation of or mistakes in the measurement of access recirculation causes a discrepancy between dialysis prescription and the actual dose of dialysis administered. Moreover, access recirculation is known to increase during a dialysis session. Therefore, the evaluation of recirculation is necessary to correctly prescribe dialysis and the ideal measurement method should be very accurate and feasible at any moment during a dialysis session.
