I hope a doctor or nurse or respiratory therapist can correct me, but my layman’s impression is that intubation itself isn’t causing deaths as much as having to be intubated means you’re already in dire straits.
I was recently intubated 3 times in the last month and had no ill effects. I know that’s just an anecdote but no doctor ever told me it would be super risky. The alternative to not getting it however usually meant death.
