It was yeh, to be told afterwards that you’re 24 hours away from potential death is quite something!Damn, that's basically the absolute worst-case scenario. I suspect my sister is going the same way based upon her symptoms.
Glad you got through it.
If your sister if going through the same then I’d suggest that she keeps a log of everything (if she isn’t already) and continues to put pressure on the hospital staff to get it dealt with.
