In the hospital I work in, patients who are seriously ill but have the competency to comprehend the gravity of the situation they are in, have the option to sign a 'no resuscitation' declaration. Most do, presumably because they accept that things aren't going to get much better. The 'dubious' part I suppose is when the patient isn't mentally able to make that kind of decision, and relatives try to enforce their views on doctors, for the right reasons or not. Good doctors take the patients requests as paramount. Good doctors take all their expertise into a prognosis of their patients into account. Excellent doctors can ignore pressure from distraught family to save the unsaveable. Excellent doctors can also do their best to save anyone with half a chance, and they do, believe me, they literally perform miracles everyday!!. Please, leave it up to the doc's, they do actually know what their doin :-)
