1. An oxygenator for an extracorporeal ventilation system, the oxygenator comprising:
a gas passage and a blood passage arranged to allow gas exchange of an oxygenation gas supply with blood via a gas-blood interface, the gas-blood interface being separated into a plurality of interface regions, wherein the gas passage leads from a gas inlet zone via the gas-blood interface to a gas exhaust zone, and wherein the blood passage leads from a blood inlet via the gas-blood interface to a blood outlet and
a supply gas distribution arrangement comprising:
one or more partitions each in contact with an outer wall of the gas-blood interface to divide the gas inlet zone into a plurality of gas inlet sections, each gas inlet section having a border with a different interface region of the plurality of interface regions, and
a plurality of gas inlet ports each configured to receive a separate inlet gas supply, a separate gas inlet port being provided for each gas inlet section thereby allowing the oxygenation gas supply to be modulated differently for different interface regions of the gas-blood interface,
wherein the different interface regions are arranged successively in blood flow direction for blood directed through the gas-blood interface to pass each interface region, and wherein the gas-blood interface is uniformly distributed within the blood passage.
