I saw one article that said over 50s have just over 30% survival rates after going on a ventilator. That's scary. The problem as I see it is they have no idea how to treat this illness and as such a trip to a ventilator is nothing more than palliative care.
You need to be careful about reading too much into individual stats @donnyred. I know it's a worrying figure, but you have to allow for why people end up on ventilators, their co-morbidities, and lots of other variables.
Yes, it's a horrific and scary illness, but all we can do is treat the symptoms and hope the immune system is strong enough to prevent serious consequences.
