I believe (iirc) the initial data from China in early 2020 was like >98% of the people being put on vents never made it off, I seriously doubt any of the people ever made it out of the hospital. (going off memory) Most of what was happening was a lie, some lies had some truth to them, other lies were just naked. Again, the numbers can vary but I have serious doubt the vents helped the people with a respiratory disease.
The people that supposed died from covid more or less died from some other alignment, disease, condition, etc. that already existed. Covid simply quickened the pace. My bet is the vents contributed to additional deaths but I think that is a more difficult discussion.
The issue I have with her is more factual even at common sense level, nobody is promoting what she appears to be doing. She traded a somewhat know thing, to a whole thing that now includes serious unknown long term issues. Its her choice there.
