    摘要: A method for providing oxygen rich gas for blood oxygenation not performed on a living human or animal body, said method comprising selectively operating an oxygen concentrator in one of two operating modes, wherein a first operating mode comprises operating from battery power, and a second operating mode comprises operating from an external power source, delivering oxygen from the oxygen concentrator without scrubbing to a blood oxygenator when the oxygen concentrator is operating in a first one of said two operating modes, and combining oxygen from the oxygen concentrator with a carbon dioxide-scrubbed oxygen gas stream and delivering the combined gas stream to the blood oxygenator when the oxygen concentrator is operating in a second one of said two operating modes.

    摘要: The present invention generally relates to a process suitable for extracorporeal lung support. The process comprises contacting blood with a dialysis liquid separated by a semipermeable membrane. Oxygen is introduced into blood and/or into the dialysis liquid prior to contacting blood and dialysis liquid being separated by the semipermeable membrane. The process is versatile and allows for blood oxygenation as well as removal of at least one undesired substance occurring in the blood, selected from carbon dioxide, bicarbonate and hydrogen cations, from blood. Thereby, the present invention takes advantage of the Haldane effect in the extracorporeal contacting step. The undesired substance can be efficiently transported across a semipermeable membrane to the dialysis liquid. In contrast to extracorporeal carbon dioxide removal methods of the prior art (ECCCbR), the present invention employs a versatile dialysis liquid that allows to adjust the pH and buffering capacity of the dialysis liquid, to add fluids to the dialysis liquid and/or to the blood and to remove substances from the blood in the extracorporeal circuit, depending on the conditions and needs. The present invention also provides regeneration and recycling of the dialysis liquid, and thus for its repeated use. The present invention is suitable for treating human or animal subjects suffering from lung failure or lung disorders.
