Well, the original post said they were flying aircraft while still impaired afterwards ...
Anyone who's worked for a big corporation will know what I mean. "what the anti brbary course dint we do that 6 weeks ago "

As both of those use NAD+ as cofactors, something that may sober someone up faster without causing hangover symptoms is a combination of tryptophan and niacin, but only to the extent that NAD+ availability is a limiting factor in the liver. A dietary sufficiency of zinc is necessary for production of alcohol dehydrogenase. Experiments suggest that 1 g fructose/kg body mass also helps process alcohol faster, but I'm not clear on how, and the research has inconsistent reproducibility.
If you have a healthy diet already, and have a healthy liver, there is very little you can actually do to sober up faster, beyond building up a tolerance, which increases the amount of alcohol dehydrogenase your body produces when exposed to ethanol.
The pure oxygen may counteract some of the symptoms of drunkenness and hangover, but the health effects of hyperoxia can be even worse than ethanol intoxication. It would be less dangerous to intravenously infuse tryptophan and niacin-associated nicotinamides, or use direct hepatic injection, and even that sounds reckless.
Short version of the paper (hopefully accurate enough):
The alcohol in the body is "burned" in a chain of multiple reactions. Using multiple steps because you can store the energy extracted in each step and store it in ATP or NADH to use it later in other reactions.
The first step is to extract two Hydrogen from the alcohol CH3-CH2-OH --> CH3-CH=O. This step needs an enzyme. There is not too much of this enzyme, so a small amount of alcohol saturates the maximum conversion capacity (that is ~7g/h). All the other steps have a better conversion rate, so this is the important step for alcohol metabolism.
Note that this step doesn't use oxygen. Oxygen is use in the step four and later. (I'm not sure if I'm counting all the steps correctly, but the use of oxygen is much later.)
It may wake you up a bit, you're still impaired relative to where you'd have been without the alcohol in your system (or lack of sleep or whatever other impairment is present).
Overall I think the guy above boiled it down pretty well, some mistakes were made, but these marines were not prepared with enough training or properly functioning equipment to do the job safely, and senior commander’s are just pointing the blame at the squadron and middle management instead of taking ownership of the real problem (not responding to warnings about unpreparedness).
There is also oxygen dissolved directly in blood rather than saturating hemoglobin, but that constitutes a tiny fraction of o2 in comparison.
Please don’t make shit up.
