I couldn't make sense of what you wrote until the last line. From personal experience, and reading several of the accounts here, I believe that hospitals in the US do not respect sleep, almost willfully so.
This isn't universally true. I'm happy to report that the Cardiac Surgery step-down unit at Boston Children's does a fantastic job working with families to determine the least intrusive modes of nursing care based on their needs & condition.
Thanks, that's good to know! The topic was discussed here a few months ago [0]. It's probably difficult to get the data required for a systematic discussion...
