Abstract
An oxygenator (10) for an extracorporeal ventilation system comprises a gas passage and a blood passage arranged to allow gas exchange of an oxygenation gas supply with blood via a gas-blood interface (34). The gas passage leads from a gas inlet zone (28) via the gas-blood interface (34) to a gas exhaust zone (40). The blood passage leads from a blood inlet (12) via the gas-blood interface (34) to a blood outlet (14). The oxygenator comprises a supply gas distribution arrangement (26, 28A, 28B). This allows the oxygenation gas supply to be modulated differently for different interface regions of the gas-blood interface. The oxygenator can be used to remove or reduce the formation of gaseous microemboli bubbles.
