Claim Text:
1. An arrangement for removing carbon dioxide from an extracorporeal flow of blood, comprising: a filter comprising a membrane that separates a blood region through which the extracorporeal flow of blood is passed from a gas region through which a flow of a purge gas is passed; a cleaning unit that removes carbon dioxide from the flow of the purge gas passed through the gas region of the filter; and both downstream and upstream of the filter one carbon dioxide sensor is provided for each location for determining the carbon dioxide content of the purge gas, and each carbon dioxide sensor is operably connected to a control unit so that carbon dioxide content values determined by the carbon dioxide sensors are displayed via a touchscreen of the control unit, wherein the purge gas does not include oxygen and is an inert gas selected from the group consisting of nitrogen, helium, neon, argon, xenon and krypton; or the purge gas does not include oxygen and is a mixture of two or more gases selected from the group consisting of nitrogen, helium, neon, argon, xenon and krypton.
