The invention relates to a method and a device for determining at least one operating parameter of a device for extracorporeal blood treatment as a function of the absolute pressure such that the absolute ambient pressure is first set in a closed container filled at least partially with air and next with delivery means a predetermined sequence of delivery strokes of a liquid is delivered into the container or out of the container, the increase or decrease in the relative pressure in the container is measured after each delivery stroke, the total volume delivered and the relative pressure after each delivery stroke are assigned to a value pair, the absolute pressure and/or the initial air volume is/are determined on the basis of the Boyle-Mariotte law and in additional steps the at least one operating parameter is calculated and adjusted as a function of the absolute pressure. |
