Abstract
Using the WADIC(Waseda Automatic Dialysis Controller) beside monitoring system for toxic substances and water removal from HD patients, short time dialysis is safely performed with a high clearance dialyzer. Performance estimation of short time dialysis using the WADIC system shows almost the same results as by. chemical methods using creatinine as a marker. A newly developed system for monitoring water removal is in use for clinical treatment, which is composed of a pressure transducer and a microprocessor and could be attached, to any positive pressure type console.
