- a gas circulation device providing a flushing gas capable of being placed in fluid communication with one or more oxygen or oxygen and carbon dioxide depletion devices,said gas circulation device comprising, in fluid communication with each other;
a flushing gas source;
a gas outlet manifold;
a first gas sterilization filter;
a second gas sterilization filter;
one or more gas sensor assemblies;
a gas inlet manifold; and
a controller,wherein at least one of said one or more gas sensor assemblies is selected from the group consisting of an oxygen sensor, a carbon dioxide sensor, and a combination thereof, and said gas sensor assemblies comprise a partial pressure sensor.

Abstract
A portable assembly for processing red blood cells RBCs including a disposable blood collection set including a blood bag, an anaerobic storage bag and an oxygen and/or oxygen and carbon dioxide depletion device disposed between the blood collection bag and anaerobic storage bag. The portable assembly further provides for a gas circulation device in fluid communication with the oxygen or oxygen and carbon dioxide depletion device. The gas circulation device includes a pressure source that is able circulate flushing gas through the depletion device as RBCs pass from the blood collection bag, through the depletion device and into the anaerobic storage bag.
