Abstract
A method controls a device for extracorporeal blood gas exchange. The device has a membrane as a gas-liquid barrier between a bloodstream and a gas stream. The membrane further makes possible a passing over of the carbon dioxide content from the bloodstream into the gas stream. The device has at least one actuator. A change in a value of an operating parameter of the actuator brings about a change in a value of the carbon dioxide content that passes over from the bloodstream into the gas stream. The method further includes providing breathing gas information that indicates a carbon dioxide concentration in breathing gas and providing a control signal, which indicates a request for setting a value of the operating parameter and changing of the value of the operating parameter as a function of the carbon dioxide concentration in the breathing gas.
