Method for measuring effect of hemodialysis, hemofiltration or hemodiafiltration treatment

摘要

Method of measuring the effect of a dialysis or similar treatment whereby a fraction of the used dialysis fluid is extracted downstream of the dialyzer for analysis of at least one substance, i.e. urea, whereby said fraction of dialysis fluid is extracted via a branch conduit (8) containing a pump (6). The method according to the invention is characterized in that the total amount of used dialysis fluid is measured, in that the proportion and/or amount of said substance in the extracted fraction is measured and also in that the total amount of said substance removed from the patient is calculated with the help of these values. The invention is preferably intended for use in connection with haemodialysis, haemofiltration and haemodiafiltration. IMAGE
