It's not like we're going around incubating healthy people -- you have to be pretty sick to get put on a ventilator. Even if the treatment turns out to be a net negative, most of these patients didn't have very good odds in the first place, so it's pretty unlikely it would affect the death rates "drastically."

Sources? I would disagree, reports show that by not intubating, outcomes are dramatically improved. [1][2]

I'm taking issue with the use of the word "dramatically" not the claim that it could improve patient outcomes.

Sounds like mincing words. Still you have not provided sources to support your assumptions whatsoever.
