Anatomy of a life support system! The big tubes going into Elizabeth's nose are hooked up to the ventilator; the tube in her chest is to administer drugs into her bloodstream (and also nourishment if necessary - although the good news today is that she's taken a few feeds of mik, via the small tube up her nose that goes into her stomach. There are also various sensors attached here and there to measure temperature, heart rate, blood pressure etc etc. A further line goes into her foot slowly administering various other things. All in all it's quite a palaver untangling everything when we turn Elizabeth over !!
