In the first go around with Covid, and I know as I was an early adopter and got really hammered (though fortunately I stayed out of the hosptial) they were intubating everyone very early. Partly I think because that secured their airway and they didn’t have real PPE. Nobody was going on HFNC or bipap. That proved to be a problem and early research suggested that it was increasing mortality. We were looking at Europe as they were a few weeks ahead of us, and remember we were making it up as we went using bad data as well sometimes. Ultimately I called around to friends in a few different area hospitals to make sure if I went in I wouldn’t be immediately tubed and sedated. 2 we’re still doing that, one wasn’t. So that was the plan.
So yes, those that got the vent were already circling the drain, and most died. From Covid, clots, pneumonia, ARDS and multi organ failure, etc. However, some of those, especially in the first few months, and even later if the backwards non evidence based places, could have probably been salvaged.
