Abstract<\/h2>\n
Extracorporeal carbon dioxide removal (ECCO2<\/sub>R) is an emerging technique designed to reduce carbon dioxide (CO2<\/sub>) levels in venous blood while enabling lung-protective ventilation or alleviating the work of breathing. Unlike high-flow extracorporeal membrane oxygenation (ECMO), ECCO2<\/sub>R operates at lower blood flows (0.4\u20131.5 L\/min), making it less invasive, with smaller cannulas and simpler devices. Despite encouraging results in controlling respiratory acidosis, its broader adoption is hindered by complications, including haemolysis, thrombosis, and bleeding. Technological advances, including enhanced membrane design, gas exchange efficiency, and anticoagulation strategies, are essential to improving safety and efficacy. Innovations such as wearable prototypes that adapt CO2<\/sub>\u00a0removal to patient activity and catheter-based systems for lower blood flow are expanding the potential applications of ECCO2<\/sub>R, including as a bridge-to-lung transplantation and in outpatient settings. Promising experimental approaches include respiratory dialysis, carbonic anhydrase-coated membranes, and electrodialysis to maximise CO2<\/sub>\u00a0removal. Further research is needed to optimise device performance, develop cost-effective systems, and establish standardised protocols for safe clinical implementation. As the technology matures, integration with artificial intelligence (AI) and machine learning may personalise therapy, improving outcomes. Ongoing clinical trials will be pivotal in addressing these challenges, ultimately enhancing the role of ECCO2<\/sub>R in critical care and its accessibility across healthcare settings.<\/div>\n

Key Points<\/h3>\n
    \n
  1. ECCO\u2082R as an Alternative to ECMO:<\/strong> Unlike ECMO, which supports both oxygenation and CO\u2082 removal, ECCO\u2082R operates at lower blood flows (0.4\u20131.5 L\/min) and is primarily designed to control hypercapnia while enabling lung-protective ventilation strategies.<\/li>\n
  2. Applications in ARDS and COPD:<\/strong> ECCO\u2082R is most commonly studied in acute respiratory distress syndrome (ARDS) and acute exacerbations of chronic obstructive pulmonary disease (AECOPD), where reducing mechanical ventilation intensity is crucial for minimizing ventilator-induced lung injury.<\/li>\n
  3. Limitations and Safety Concerns:<\/strong> Complications such as hemolysis, thrombosis, and bleeding hinder the broader adoption of ECCO\u2082R. Higher-flow devices (>500 mL\/min) provide better CO\u2082 clearance but may increase shear stress and coagulation risks.<\/li>\n
  4. Technological Advances in ECCO\u2082R Devices:<\/strong> New membrane designs, including carbonic anhydrase-coated membranes and electrodialysis, enhance CO\u2082 removal efficiency while minimizing blood trauma.<\/li>\n
  5. Hemolysis and Thrombosis Risks:<\/strong> Shear stress from extracorporeal circuits contributes to red blood cell destruction and coagulation activation, requiring optimized anticoagulation strategies such as citrate-based anticoagulation over heparin.<\/li>\n
  6. ECCO\u2082R in Avoiding Intubation:<\/strong> In COPD patients failing non-invasive ventilation, ECCO\u2082R may help avoid intubation, though data on mortality benefits remain inconclusive.<\/li>\n
  7. ECCO\u2082R as a Bridge to Lung Transplantation:<\/strong> Patients with end-stage lung disease awaiting transplantation may benefit from ECCO\u2082R to maintain gas exchange while avoiding the risks of invasive mechanical ventilation.<\/li>\n
  8. AI and Personalized ECCO\u2082R Therapy:<\/strong> The future of ECCO\u2082R includes AI-driven algorithms to adjust CO\u2082 removal in real-time, optimizing patient-specific settings to improve efficacy and safety.<\/li>\n
  9. Integration with Renal Replacement Therapy (RRT):<\/strong> Some ECCO\u2082R systems are being combined with renal support to provide simultaneous CO\u2082 clearance and fluid management in critically ill patients.<\/li>\n
  10. Future Research and Clinical Trials:<\/strong> Large-scale randomized trials are needed to establish the clinical efficacy of ECCO\u2082R, particularly in comparison to standard ventilation strategies and ECMO alternatives.<\/li>\n<\/ol>\n
