Thats what I found with a quick Google, Im sure if I spend an hour or longer I can find more. All I can tell you is what I read posted all over the Physician work areas regarding Covid treatment. I think we have an emergency physician on this thread "Dre" whom can maybe explain it in better detail not saying its in use at his hospital, Ive only seen it posted at two different emerency departments not every hospital has it posted.
It took us less than a minute to do the search to show you that you were incorrect in your assertions. If you have to spend an hour searching for something to support your argument you're looking for a non-existent needle in some haystack somewhere.
