I think the big problem is medical technicians and doctors. My feeling is that we should be focusing on training up medical people on a massive scale, as that's something that the USA is notoriously bad at. Perhaps the military could provide medical technicians the fastest? lots of healthy young people who are trained in the use of serious PPE? (I wonder how the procedures differ between nuclear, chemical and biological threats like these?)
People talk about beds... but the problem isn't physical beds. I could make you a physical bed. the problem is doctor and medical technician labor to make the bed useful.
