1. A method for altering treatment parameters of a treatment apparatus used for dialyzing a patient over a plurality of treatment sessions, the method comprising:
determining a diffusive total target sodium balance;
determining a transitional treatment regimen by which the diffusive total target sodium balance is achieved over the plurality of treatment sessions, wherein determining the transitional treatment regimen comprises:
specifying, prior to starting a first treatment session, a first corrected volume by mathematically adjusting the value of a first initial ultrafiltration volume in order to achieve a target dry weight or another weight target value;
controlling, based on the determined transitional treatment regimen and while dialyzing the patient, the following:
an ultrafiltration pump of the treatment apparatus; and
a concentration of sodium chloride in a dialysis liquid used by the treatment apparatus;
and adjusting a second initial ultrafiltration volume to be withdrawn during a second treatment session of the plurality of treatment sessions to a second corrected volume of the second treatment session in order to achieve a second ultrafiltration volume of the second treatment session, wherein:
the second corrected volume of the second treatment session of the plurality of treatment sessions is less than the first corrected volume of the first treatment session.
