Abstract
A device for determining the access flow rate of a patient when connected to a blood treatment machine performs a measurement phase (), in which the blood treatment machine is caused () to operate in first and second operating states, wherein the second operating state at least differs from the first operating state by a change of flow direction of blood or treatment fluid through a dialyzer of the blood treatment machine. Based on sensor values representing a fluid property () of the treatment fluid in the first and second operating states, the device computes () a measurement value of comparison parameter (e.g. a ratio or a difference) that compares treatment efficiency in the first operating state to treatment efficiency in the second operating state, and determines (), based on the measurement value, an estimated value of the access flow rate.
