Cerner is an ancient Sumerian name for Satan. In the legend, McKesson is his faithful cohort. Be warned.
Despite the lies that the pretty sales girl just out of college told you a core 2 thin client with 4 gigs of RAM is not enough horsepower to run Windows 7/10, your institution's security software, Dragon, your EMR, your single sign on software, the doc using google/uptodate/epocrates/mdcalc, the nurse shopping for shoes on Amazon, and various servers pushing updates. Every computer in your department should be at least an i5 with 8 gigs of RAM. Mission critical machines that physicians are using should be i7s with 12-16. Instantaneous response should be the bar to clear for your hardware. Your people cost too much per hour to have them sitting around waiting on cheap computers.
There's not much in life more useless than the fuel that's not in your gas tank, the sonosite locked away in radiology, or the glidescope that is locked away in the OR.
You can either have two oxygen ports in your rooms to facilitate apneic oxygenation while intubating or one oxygen port and an extra respiratory therapist (to blow into the O2 tubing of the BVM or nasal cannula, your choice).
Don't pay someone a lot of money to come up with a list of things to fix. The people you work with can probably give you a better (and longer) one for free.
Good luck with your launch
