Interesting. I had wondered if blood transfusions could help. It may just delay the inevitable and provide more food for the virus, or it may buy the body enough time to develop its own antibodies. Perhaps a 1-2-3-4 punch - HQC-ZPak-Zinc-fresh blood.
First of all there is nothing fresh about blood given in transfusion. Secondly transfusing unless absolutely necessary is more detrimental than good. It is the single worse thing one could do
Hypobaric oxygen treatment would allow the blood plasma to carry oxygen. Might save some while the hydroC and zync or Erythromycin kicked in.
