The amount of oxygen they take from the air is fairly small, but,

This doesn't make sense to me, I'm afraid. The amount of oxygen
being used up in the room is the amount being converted into CO2 by
the patient. The oxygen concentrator won't alter that significantly.

Are you *sure* about that?

Yes. The O2 doesn't disappear out of the room.

The only reason I said "The oxygen concentrator won't alter that
significantly" is that I was thinking the patient might need to make
less effort breathing with the concentrator, and so would use up less of
the O2.

COVID is very hard on the lungs.

An ECMO machine could keep you alive, even if you were
brain dead and your lungs were completely filled with
fluid. It could even keep you going, until a lung transplant
could be arranged. But with the number of people with damaged
lungs, there would not be enough car-accident victims to
serve the lung-transplant queue.

Any time you spend at home, sick with this stuff, is "fools time".
A major risk is blood clots, not a bit of coughing and breathing
difficulty. People who have been "whiny but otherwise OK",
have clotted out in their sleep, and are found dead in the
morning. I don't think there's much profit in "toughing it
out at home", if what you really need is heparin blood thinner
and a watchful eye kept on you for internal bleeding.

By all means, have an oxygen concentrator, but be aware
there are other risk factors that compromise the outcome.
You could be maintaining "parity" with your opponent using
the oxygen concentrator, while inside you, every cubic inch
is full of clots.

For some reason, on young people, this manifests as "COVID toe",
where the clots are in the feet.
