摘要：
An extracorporeal blood treatment apparatus, comprising: a blood treatment device (2) having a blood chamber (3) and a fluid chamber (4) separated by a semipermeable membrane (5) an extracorporeal blood circuit (6) connected to the blood chamber to transport blood from an individual (7) into the blood chamber (3) and to return blood from the blood chamber to the individual a sensor (10) arranged beforehand in the extracorporeal blood circuit (6) for emitting at least one signal indicating variation of blood volume (ΔBV) individual (7) subjected to the extracorporeal blood treatment a sensor (14) configured to output at least one signal indicating the weight loss of the individual (7) subjected to the extracorporeal blood treatment a system of weight loss to enable the individual weight loss during extracorporeal blood treatment a control unit (20) configured to perform the following operations: - receive signals indicating a relative variation in blood volume (ΔBV), and weight loss during extracorporeal blood treatment - acquiring a desired value (IRDES) of a parameter of the individual, wherein the parameter of the individual (IR) comprises an index that is based on the patients ability to reabsorb, cells of the tissue, the mass of liquid subtracted from the plasma portion of blood, or an index that is a function of the amount of fluid moving from the interstitial space of the patients body to the intravascular space thereof wherein the control unit (20) is further configured to perform the following operations: - determine a calculated value (IR) parameter of the individual function of the relative variation in blood volume (ΔBV%) and a variation weight loss (ΔWL%) of the individual - control system weight loss based on the desired value (IRDES) of the individual and the calculated value (IR) of the individual.Un aparato de tratamiento sanguíneo extracorpóreo, que comprende: un dispositivo de tratamiento sanguíneo (2) que tiene una cámara sanguínea (3) y una cámar
