The journal The Lancet Respiratory Medicine has just published a review article on an extracorporeal gas exchange technique (CO2 removal). Dr. Jordi Mancebo, director of the Sant Pau Intensive Care Unit and member of the International ECMO network, is one of the co-authors of the publication. The article “Extracorporeal carbon dioxide removal for lowering the risk of mechanical ventilation: research questions and clinical potential for the future” proposes recommendations for both clinical practice and research in this area. This technique is currently used in the Intensive Care Unit with selected patients.
