Viagra was used sparesly at the start of this shitshow when Dr's realised even at 100% oxygen patients were still not getting enough to keep them alive. They thought along the lines of altitude sickness, where in an emergency Viagra can be used to help with the flow of oxygenated blood. Many were talking about it, and seeing it work when their patients were at full oxygen.

It was because the cells were stripped of oxygen...radiation poisoning.
