Patent ID: 11833282

Abstract:
Described herein is a process suitable for extracorporeal lung support that relies on exposing blood, separated by a semipermeable membrane from the dialysis liquid. The dialysis liquid comprises a buffering agent and has a high buffering capacity for H+ ions. Carbon dioxide, bicarbonate and hydrogen cations can be efficiently transported across a semipermeable membrane to the dialysis liquid. This also allows for the regeneration and recycling of the dialysis liquid, and thus for its repeated use. The versatility of the dialysis liquid allows adjusting the pH of the dialysis liquid, add fluids to the dialysis liquid and/or to the blood in the extracorporeal circuit and to remove substances from the blood in the extracorporeal circuit, depending on the conditions and needs. Thus, the process is versatile, and suitable for treating or preventing respiratory acidosis, metabolic acidosis, diseases associated with lung malfunction and/or kidney malfunction and/or liver malfunction.
