The official and accepted Jewish Law (Halacha) in this matter is as follows:
      
    "You are not required to hook up a terminal patient whom the doctors have certified as having no hope for recovery to an artificial life saving device such as a respirator or feeding tube, if that person does not wish to have such measures taken. However, once that person has been hooked up to such a device, it is absolutely forbidden for that device to be disconnected and to do so constitutes murder in the first degree"

I did not want to bring religion into this thread to begin with, but was arguing from a humanitarian point of view. But being that I was now asked for a religious ruling you now have it in black and white.
