“…These devices are not yet commonly used in HD units (they are relatively high cost), though some centres mandate their use for home HD 10 . For example, Huang reports an integrated wireless flexible sensor and virtual internal impedance model to detect blood leakage during dialysis therapy 11 ; successful experimental results show the feasibility and potential of commercial design. Similarly, Ou 12 reported the successful test of a blood leakage device using flexible‐array sensing technology, which also improved the HD experience for the patient, by giving them reassurance of safety in the process.…”

There are currently more than 2 million end-stage kidney disease (ESKD) patients who require kidney replacement therapy worldwide, 1 and this is estimated to rise to over 5 million by 2030. 2 While a kidney transplant is the ideal therapy, hemodialysis (HD) is used by the majority (60-70%) of ESKD patients. 3 HD requiresvascular access via a central vascular catheter, an arteriovenous fistula, or a synthetic graft. Hemodialysis with a fistula or graft requires the insertion of two needles to access the blood flow; venous needle dislodgement can happen when the venous needle becomes dislocated out of the vascular access, resulting in blood loss. At typical hemodialysis blood flow rates of 400-500 mL/minute, it can take only minutes for the patient to lose over 40% of his or her blood volume (the point at which hemorrhagic shock occurs). 4 VND represents a potentially life-threatening situation and a real cost to the patient and the health service, with interventions required including ICU or emergency department admissions, increased erythropoietin use, pathology testing and blood transfusions. 5

“…Optical sensors have also been proposed to detect hemolysis [9] or improve the monitoring of filtration rate [10]. In another recently proposed solution, electrical measurements are used to detect blood leakage [11].…”

This paper presents a compact, low-cost, and noninvasive system for real-time estimation of plasma sodium concentration ([Na]Pl) during a hemodialysis (HD) session with state-of-the-art accuracy. It is based on electrical impedance spectroscopy (EIS) performed with a capacitively-coupled impedance sensing cell and a high-frequency measurement device, both custom-built. The EIS data are processed to infer the resistance of the liquid inside the cell, which is used together with an optical hemoglobin sensor to estimate the [Na]Pl. Validation of the EIS was performed by estimating the conductivity of bloodmimicking fluid (BMF). The complete method was validated using whole bovine blood, comparing the results to those obtained with standard instruments. The system was able to estimate the [Na]Pl with sufficient accuracy (RMS error of 3.0 mol/m 3 with respect to reference data) to provide clinically useful information. The proof-of-concept hardware can be converted to a cheap and compact circuit board for integration into an HD machine.
