Long video but worth the watch. In it, the Doctor states that 80%-90% of the people that go on to a ventilator are so far gone that they will die so this is certainly not a surprise.
Perhaps another way to look at this is that people are put on a ventilator because the alternative is to watch them quickly die.
When I recovered enough after two days to be taken off a ventilator, I had a serious cut on my nose. Now there is a very visible scar across the tip of my nose. Nobody ever said a word about how I was thus injured. My assumption is that it happened during the rush to get air into me to prevent my immediate death.
People are dying! Nobody should ever die! Ever!
