ICUs run at 80 to 90% all the time...
How many are there for something else but test positive for Covid?.
I tell that to people all the time.
Any hospital worth its salt runs its hospital at the highest occupancy rate that it can, reserving enough space for an influx. IIRC, 70-75% or below occupancy rate is undesirable.
When you realize there are a lot of people staffed RNs, Physicians, Respiratory Therapy, expensive equipment, and everything that goes along with that, you don’t want them idle. You want as many of them employed treating patients and the hospital getting paid for it.
You need to keep some head space, but...not too much.
