This appears to be continuing research by a group which previously released a paper in 2012 [1] that got some coverage. This trial put numbers of shelf life, and demonstrated successful in vivio animal testing. For anything beyond short term usage it would also be necessary to deal with CO2 build up to prevent acidosis, but in a poor blood oxygenation situation even a few dozen seconds can count, and the ability to directly introduce oxygenation in the minutes before someone could be hooked up to artificial respiration might result in dramatically improved outcomes. Given the relatively long reported stability (2 months) I wonder if an "oxygen injector" might have a place in emergency kits in certain occupations as well, even if it only can add a couple of minutes of performance. 1.
