@RunningAwaywiththeCircus. In the papers a few says ago, a dr in italy said in his hospital, none of those ventilated survived.
However, this may have been just his experience, (at that time) as the papers here, have many stories of those on ventilators who have survived.
No health system in the world (private or state controlled) can keep hundreds (or thousands) of empty beds in case of a pandemic, so there is always going to be a need for 'pop up hospitals'. Before the conference centres were announced, I was assuming they would co opt a hotel, or similar.
Similarly, it is not possible to keep thousands of ventilators, or PPE unused, just in case there is a pandemic, as they are likely to degrade over time, and be out of date ( designs change, etc).
The question is, how quickly can popup hospitals be created, and how quickly equipment can be produced, procured and delivered to the right areas - hospitals, surgeries, care homes, etc ( as appropriate)
