AI summary

A method of operating an extracorporeal blood treatment includes, prior to commencing an extracorporeal blood treatment, reading from a storage device (4a, 5a) stored values of a patient-specific prescription parameter. These stored values relate to a sequence of previous extracorporeal blood treatments. In addition, the method includes processing the stored values of the parameter read from the storage device (4a, 5a) according to a predetermined algorithm to determine a current value of the patient-specific prescription parameter. The current value is then available for the subsequent extracorporeal blood treatment.
