Utilization and outcomes of extracorporeal CO removal (ECCO R): Systematic review and meta-analysis of arterio-venous and veno-venous ECCO R approaches.

Introduction: Extracorporeal carbon dioxide removal (ECCO R) provides respiratory support to patients suffering from hypercapnic respiratory failure by utilizing an extracorporeal shunt and gas exchange membrane to remove CO from either the venous (VV-ECCO R) or arterial (AV-ECCO R) system before return into the venous site. AV-ECCO R relies on the patient's native cardiac function to generate pressures needed to deliver blood through the extracorporeal circuit. VV-ECCO R utilizes a mechanical pump and can be used to treat patients with inadequate native cardiac function.
