  • Method for determining adequacy of dialysis based on urea concentration
    Patent number: 5405315
    Abstract: A method for determining the adequacy of dialysis, using determination of urea concentration in the dialysate effluent with an enzymatic electrode incorporating a urease sensor, and conversion of this information to arterial urea nitrogen utilizing a "flow ratio" correction; and utilizing the arterial blood urea nitrogen derived from readings of an on-line monitoring sensor as an absolute quantity, and the urea reduction ratio as a relative quantity as a new end-point for dialysis adequacy.
    Type: Grant
    Filed: February 15, 1994
    Date of Patent: April 11, 1995
    Assignee: Raja N. Khuri
    Inventors: Raja N. Khuri, Nazih L. Nakhoul
