I agree there is not nearly enough evidence to draw a conclusion. That's why I said, there have been no controlled studies either way at this point so no one can say for sure. All we have is anecdotal reports, plus the fact that significantly more COVID patients die on ventilation than the average pneumonia patient who is [invasively] ventilated. Since doctors were ventilating patients at the same O2 saturation points as usual, we can say at least that something is markedly different with COVID induced ARDS from typical ARDS that makes invasive ventilation particularly insufficient, if not actively harmful.
