Like our “just in time” supply chain and logistics systems, our hospitals eschew an excess inventory of anything, including beds, ventilators, etc. Even if hospitals cancel all nonessential procedures (which would cost them a huge amount of money), there won’t be enough beds. There will be nowhere near enough ventilators. Best hope is to slow this down, or find a drug/treatment that averts crashing our healthcare system.
I would not doubt it if we see a bunch of fema trailers being rushed to hard hits spots and set up as temp covid facilities.
