<unk> <unk>  is the<unk>  of<unk><unk>  (CO2) from the bloodstream in people who have elevated levels of<unk><unk>  as a result of respiratory failure. The use of<unk>  is currently considered experimental, but it has been studied in a number of situations, specifically severe exacerbations of chronic obstructive pulmonary disease and in adult respiratory distress syndrome where conventional mechanical ventilation would cause excessive lung damage. It requires the insertion of a tube similar to a dialysis catheter into a large vein. Blood is pumped through a machine where the<unk><unk>  is filtered out.
