There is a hypothetical case of a coma. I want to know if doctors have the right to unplug the person. What happens when the chances of waking up are very nil? What happens when the chances of waking up are low and it can take several years for the person to wake up? I read this article which says medically futile life sustaining treatments are left to the doctor's choice. http://www.fammed.ouhsc.edu/Palliative-Care/documents/Medically Futile Care.ppt But, I heard doctors cannot unplug people like that. What's the deal?
