Well maybe the news I got is fake, or old, but...
Yes, of course we should learn a lot from this experience.
It is old and truly I am not criticizing your post. This was the bad information, spread somewhat by my own profession early on. We also got swept up in emotion and did not continue the tried and true. The fact is that ARDS, including ARDS CoVID has about a 40% mortality once there is mechanical ventilation.
