The problem is that with the infection spreading exponentially you might have hospitals half empty one day and at 200% a week later.
Here in Czech Republic it looks like we managed to avoid running out of capacity during the ongoing second wave, but just. The measures taken included canceling any elective and non-life-threatening surgeries, drafting medical school students, many foreign doctors that came to help and moving covid patients in critical state from overloaded hospitals hospitals.
We even built two full field hospitals which we will thankfully not need as it looks like. BTW, building one of them took about a week - which you migh not have, once you hit exponential growth. Not to mention having spare medical personnel to run it.
