A novel double parameters based biofeedback system to prevent intradialytic hypotension in clinical practice: Case report

Abstract

Intradialytic hypotension (IDH) still represents the main complication during dialysis treatment. Patient’s discomfort, reduced dialysis efficiency, reduced treatment time are only some of the main problems that could derive from the need to stop or temporarily interrupt the treatment because of IDH. Up to now, different types of treatment (HDF, HF, or AFB) have been considered to prevent IDH as well as the use of biofeedback systems (Blood Volume Monitoring, Temperature control, Sodium profiling, Blood Pressure monitoring). Recently a new biofeedback system (Biologic Fusion^®) controlling simultaneously blood pressure (BP) and relative blood volume changes (RBV) has been developed to prevent IDH. This system runs according to fuzzy logic. We describe how this system works and to a better understanding, we report a clinical case of a patient with frequent IDH treated with the use of this system.
