No. Just, no. Oh god, no.
Hospitals do not operate regularly with a full ICU.
That’s just blatantly false information to the highest.
You should ask an actual intensivist or tour your local ICU/CCU. Not sure whether my brother and friends, who are intensivists (and, likely, on call as I type this) in CA would laugh or get furious by such a statement in the midst of actually full wards. And, no, not everyone there are obese or old as some claim this virus takes hostage of.
Unlike with specialties and the doctor’s office that oversubscribes patients, it is not in the interest of any intensivist or hospital to fully occupy the ICU. Finding the right ICU capacity strain is a constant work in progress.
