That posters brother may have died, and he might have even been denied a ventilator. However this would have been because he would not survive ventilation, not because there werent enough. Even if that hospital ran put of ventilators (which is very unlikely) he would be diverted to another hospital. There are enough ventilators in the UK currently
Why would you stand in the street shouting to tell someone their son had died? Why would you not ring them? Or just stand 3ms away. 2m isnt that far
Its scaremongering bullshit.
Even if there were no ventilstors in a 100mile radius, they wont start denying ventilators randomly, it will be a clinical decision based on chance of survival. It wouldnt be a random fit and well 50 yr old.
Very elderly maybe denied ventilation because they wont survive it, they might have a DNR in place for example. This is always the case when giving medical care to very elderly/ill people.
