Development of a Multifunctional Extracorporeal Life Support (ECLS) System for Lung and Kidney Support: The Pneuma-K ECLS System

Abstract

Multi-organ failure (MOF), particularly in the coexistence of acute kidney injury (AKI) and acute lung injury (ALI), presents a significant challenge in intensive care units (ICU) and is associated with exceedingly high mortality rates. Respiratory and renal failures are frequently managed by extracorporeal membrane oxygenation (ECMO) and continuous renal replacement therapy (CRRT), respectively. However, employing these therapies using separate devices requires specialized facilities, adds to complexity, and increases the risks of clotting due to the extensive artificial surface areas involved. Therefore, an integrated device capable of providing simultaneous respiratory and renal support is essential. This paper introduces the Pneuma-K ECLS system, which incorporates a multifunctional detoxifying filter (MDF) capable of performing gas exchange and renal replacement in a single cartridge. Ex-vivo blood tests confirmed the ability of the MDF to oxygenate blood, remove carbon dioxide, and eliminate uremic toxins. In addition, animal experiments demonstrated the considerable clinical potential of this novel integrated extracorporeal life support approach. Integrating respiratory and renal support into a singular device could mitigate risks, conserve resources, and enhance the survival rates of critically ill patients suffering from concurrent lung and kidney failure.
