The invention relates to a dialysis machine having an extracorporeal blood circuit in which a dialyzer, a blood pump, and an arterial pressure sensor are arranged, wherein the dialysis machine furthermore has a compensation device by means of which the set value for the blood flow through the extracorporeal circuit can be corrected to a compensated value using the arterial blood pressure; wherein the dialysis machine furthermore has recognition means which are configured to recognize whether the arterial pressure sensor is connected to the extracorporeal blood circuit or not; and wherein the dialysis machine has an estimator unit which is configured to estimate a value for the arterial blood pressure if it is recognized by the recognition means that the arterial pressure sensor is not connected to the extracorporeal blood circuit.
