Temperature and Bicarbonate: Hemodynamic Effects During Dialysis

To elucidate the role of dialysate temperature and bicarbonate on hemodynamic parameters, plasma pH and electrolytes that potentially mediate this effect, the investigators wish to conduct a single-blinded, randomized, controlled, crossover study, specifically examining the effects of * A fixed low temperature dialysate of 35°C compared to a fixed dialysate temperature of 37°C. * A low dialysate bicarbonate concentration of 30 mmol/L compared to a high dialysate bicarbonate concentration of 38 mmol/L.
