judging by the daily death rate I would assume that there would be ventilator beds available daily and patients needing them daily. Just for reference I’ve attached the link

I’ve also come to the conclusion that the 30 sites may well be included in all the locations on the clinic gov trials website. The list below is the amount of hospitals within the states local group, granted not all of these sites will be used some children’s hospital’s and cancer clinics etc but there’s a total of 190.
Please feel free to check on each groups website for any confirmation
Mount Sinai Health for example has 8 hospital’s in New York, so I’ve come to the conclusion that this would be the main point of contact as opposed to adding another 7 sites within the same group in the same area and probably creating confusion . This would make a lot more sense 1 point of contact to organise across 8 sites much more streamlined imo

University of Southern California 45
Emory University 10
Lutheran hospital 9
Ochsner clinic 40
University of Maryland 13
Brigham and Women’s hospital 6
University of Michigan 3
Dartmouth Hitchcock 10
Mount Sinai 8
Northwell health 23
Duke University medical centre 3
Cleavland Clinic Foundation 11
University of Pennsylvania 6
Baylor, Smith & White 50
University of Virginia 13

purely assumptions here just going to put a conservative figure
on sites that have recruited at 22 as opposed to the full 30 which puts an average of only 4 patients per site which I think puts a different perspective on the outlook of recruitment time frames.
