So bleed them and then transfuse them.

Does CV attack the hemoglobin?

How else to get O2 in the blood stream to oxygenate the organs?

ECMO...but that is a last resort...in these cases.

I've seen it work in other cases...

[Mom MD]

That makes absolutely no sense. The transfusion still causes a diffuse inflammatory response in the body and we did away with blood letting as a treatment back In the days of the revolutionary war. I simply do not see this disease as an attack on hemoglobin and even if it was your proposal would kill a lot more people a lot faster

[Osage Orange]

I'd guess maybe super O2 treatments...like are being used with infections that will not heal.

Oxygen hyperbaric chambers...

Come to mind...

Had a job offer long ago to do those...Was incredibly boring...

Administer nitric oxide (NO)? You nose and sinuses deliver NO to the lungs, which is why you should always breathe through your nose.

I recommend a course of leeches ;)
