摘要： The invention relates to a method for determination of gas in a liquid, wherein the mixture of gas and liquid is delivered by a pump and is also subjected by same to a change of volume and change of pressure, operating parameters of the pump that represent the change of volume and change of pressure are detected, and the gas fraction is determined from the operating parameters of the pump, taking a system compressibility into account, wherein the system compressibility in the gas-filled pumping device is determined by a sequence of the following steps: setting a starting pressure with a pressure sensor, recording the pump position and the pressure sensor values, moving to a second pressure level, recording the pump position and the pressure sensor values in this second position, determining the spring constant on the basis of the pairs of values, and equating the spring constant so determined with the system compressibility. The invention further relates to a device for carrying out a method for determination of gas in a pumped liquid, and to a dialysis machine that contains a corresponding device.
