Forgive me if this is a cold question; I genuinely want to understand the answer. Isn't a 90% death rate of coronavirus patients on ventilators somewhat in tension with the message that we have to do everything in our power to flatten the curve so we don't run out of ventilators?

Also worth pointing out that the mortality data for those on a ventilator seems to vary a lot across health care systemshttps://twitter.com/EricTopol/status/1253172475019448321 …

Follow up: excellent thread here explaining why the 88% mortality figure for ventilators is misleading (it leaves out 3/4 of the study participants)https://twitter.com/DrJohnScott/status/1253284905414426624 …

Wait, statistical flag on the play -- 88.1% of the 2634 patients who had died or were discharged out of a total sample of 5700. We don't know enough about the rest of the sample
-
The study even notes "The absence of data on patients who remained hospitalized at the final study date may have biased the findings, including the high mortality rate of patients who received mechanical ventilation older than age 65 years."

You're not doing a good job discussing these data. This is a very limited sample and should not be presented as a mortality rate. And the number you cite doesn't account for age differences. Also, there may be patients who were on ventilation who still haven't recovered.

Not the same across all hospital networks Source :

Yeah, I saw that tweet and updated the thread. Seems like an important and interesting data point.

Does it matter how soon someone is put on a ventilator? Does a shortage lead us to use it only as a last resort, when using it sooner might’ve had a better result?

88% is higher than most others datasets, and this paper looks to be comparing only discharged alive or dead numbers, not inclusive of those still on the ventilators (or, more than half still in hospital).

I updated the thread with a tweet linking studies from other health systems, where the figures are indeed much different
