PROBLEM TO BE SOLVED: To provide a method for predicting a treatment duration of peritoneal dialysis treatment. Prediction of treatment duration is based on an ideal treatment duration, the ideal treatment duration is increased by one or more delay values, and the delay value is specific to one or more patients. Depending on the parameters, patient-specific parameters consist of catheter movements, which are taken into account during the prediction of at least one of the infusion duration, drainage duration, and final infusion duration, and the prediction time is acceptable. If it is within the range, the residence time is not adjusted and the residence time is not changed.
