Intra‐dialytic hypotension is the most frequently occurring complication during haemodialysis and can lead to serious complications. Devices that continuously and non‐invasively monitor relative blood volume (RBV) changes during HD are being advocated as a tool to maintain an adequate volume of the intravascular compartment in order to avoid dialysis hypotension. Nowadays, most manufacturers have incorporated a RBV monitor in their dialysis apparatus and two manufacturers have designed biofeedback devices that control intra‐dialytic RBV changes. The goal of RBV based biofeedback systems is to prevent a severe or abrupt decrease in blood volume in order to prevent the development of dialysis hypotension. Biofeedback technologies can diminish the severity and/or frequency of dialysis hypotension. At present, however, a completely symptom‐free HD is not a reality. The major reasons for this are patient characteristics such as cardiovascular co‐morbidity and high UF rates and a lack of understanding of the relation between RBV changes and blood pressure/ cardiovascular stability.
