Abstract: The applicability is examined of ion selective field transistors withphotocurable polyurethane membranes to control of the electrolytic composition ofdialyzing solutions used in artificial kidney apparatus, and also of plasma in patienttreated by chronic hemodialysis. The short- and long-time characteristics of theefficiency of K+-selective field transistors in continuous contact withsolutions. Comparative testing of such transistors and other sensing systems is made. Itis demonstrated that a sufficient reliability of measurements in the range ofphysiological concentrations in combination with low cost provide the possibility of usingK+-selective field transistors for monitoring of the potassium concentrationboth in dialyzing solutions and plasma in patients on chronic hemodialysis treatment.
