Is there a reliable link to the number of people on ventilators? I've only been able to find time series data for number of deaths. Which is helpful, but way too much of a lagging indiactor.
The 'critical' column on worldometers is a starting point. The general consensus is that the deaths are the most reliable, the criticals are somewhere in the middle and verified cases the least reliable due to lack of tests. But it is hard to fudge a death.
Not that I think the number of cases is grossly overstated, but Italy lists deaths from coronavirus if the patient dies for ANY reason while they are afflicted by the coronavirus. This would be the source of some "fudging" of the numbers.
For the US that critical column as been way out of date (just from what I knew of one hospital vs what it was reporting for the country several days after; I don't know if it is still far out of date).
