Decorating a hospital room


My Mum is in intensive care at the Royal Melbourne hospital at the moment and is having a real struggle. Just a few days ago we were saying good bye but she has managed to pull through. And is getting slightly stronger each day! Although she is sedated, the doctors are hoping to wake her up on the next couple of days and I really want to surprise her with a warm hospital room when she wakes up. Does anyone have any ideas for decorating. Or has previously done the same or a similar thing?
