The human body possesses a unique set of organs that are responsible for providing homeostatic balance to the body's fluids. Of these, the kidneys regulate fluid and electrolyte balance in order to maintain the intracellular and extracellular fluid v

In this paper, a computer controlled system has been developed and tested to maintain the hemodynamic stability of kidney failure patients undergoing dialysis. The system uses ultrafiltration rate (UFR) and dialysate sodium concentration (DSC) as the

To maintain the hemodynamic stability of patient undergoing hemodialysis, this article proposes a novel model-based control methodology to regulate the changes in relative blood volume (RBV) and percentage change in heart rate (DeltaHR(%)) during hem

This study aims to assess the blood volume and heart rate (HR) responses during haemodialysis in fluid overloaded patients by a nonparametric nonlinear regression approach based on a support vector machine (SVM). Relative blood volume (RBV) and elect

This paper proposes a novel model-based control methodology for a computer-controlled hemodialysis system, designed to maintain the hemodynamic stability of end-stage renal failure patients undergoing fluid removal during hemodialysis. The first obje

Fluid removal during hemodialysis leads to relative hypovolemia that may cause hemodynamic instability in end-stage renal failure patients. To maintain the hemodynamic stability of patients, this paper proposes a linear parameter-varying (LPV) system

Renal failure patients provide a good model of fluid overload with the process of hemodialysis leading to central hypovolemia. This study aims to assess if hemodialysis induces identifiable changes in ear photoplethysmographic waveform variability (P

This paper proposes a novel linear parameter varying (LPV) system to model the hemodynamic response of end-stage renal failure patients to profiled hemodialysis (PHD). Ultrafiltration rate (UFR) and dialysate sodium concentration (Na) are imposed as

This study investigates the peripheral circulatory and autonomic response to volume withdrawal in haemodialysis based on spectral analysis of photoplethysmographic waveform variability (PPGV). Frequency spectrum analysis was performed on the baseline
