Method Of Monitoring The Bicarbonate Content And The Sodium Content Of A Dialysis Solution

摘要

The present invention relates to a method of monitoring the bicarbonate content and the sodium content of a dialysis solution, wherein the dialysis solution is prepared while adding a bicarbonate component and an acidic sodium component, and wherein the method comprises the following steps:a. adding the acidic sodium component and measuring the conductivity (LF_ist,Na);b. adding the bicarbonate component and measuring the increase in conductivity (ΔLF_ist,BiC) caused by adding the bicarbonate component;c. determining the increase in conductivity (ΔLF_exp,Bic) expected due to the addition of the bicarbonate component;d. checking whether the measured increase in conductivity (ΔLF_ist,Bic) lies in an expected range of the increase in conductivity (ΔLF_exp,Bic);e. determining the total conductivity (LF_exp,D) expected after the addition of the bicarbonate component and of the acidic sodium component;f. measuring the total conductivity (LF_ist,D) after the addition of the bicarbonate component and of the acidic sodium component; andg. checking whether the measured total conductivity (LF_ist,D) lies in an expected range of the total conductivity (LF_exp,D),;wherein the measurement of the conductivity in accordance with step a.; the measurement of the increase in conductivity in accordance with step b.; and the measurement of the total conductivity in accordance with step f. are carried out by one and the same conductivity measurement cell.
