Negative pressure rooms? I dealt with that in this morning’s Q&A.
In television coverage I noticed several Hospital workers appeared to be wearing an N95 mask which they in turn had covered with a surgical mask.
Maybe to help the N95 last longer?
Don’t you have to factor the difference between regular nurses attending stabilized patients and ER/ ICU staff dealing with multiple active infections? The virus load inflicted upon those working with incoming patients is tremendous. You cannot afford “sick days” at the moment in any staff in either unit.
