"WebbEffective ionic dialysance is blood flow (Q(b)) dependent. The presence of significant (> or =5%) access recirculation (sAR) during dialysis lowers EID at a given Q(b), thereby lowering EID/Q(b). We propose using EID/Q(b) as a useful chairside tool for detection of sAR in arteriovenous fistulae (AVF). " - Recirculation of avf
