Well, all doctors have an occupational, not to mention social obligation to save their patient's life with all their skills and knowledge.
However, if a point is reached whereby the medical condition of a patient has reached a dead end or the patient can only live by life support, prolonging the patient's life will only matter to the patient himself if he can indulge in the benefit of life. In other words, he can only enjoy the satisfaction of a life only if he's conscious.
To the family, of course it is comforting to know that the person they dear is still alive although unconscious. Analytically speaking, if a person is announced brain dead, there is no chance for him to be revived but for a miracle.
I'm very confident that the doctors endorsed by the MMC are academically capable of saving a patient's life with all his will. In an episode of Grey's Anatomy, an intern (George O'Malley) is completely sure that the patient brought in by the rescue team cannot be resuscitated. However, his resident (Miranda Bailey) insists on him performing the standard procedure to resuscitate the patient although she herself knows that there's just no chance for the poor guy. In the end, she told him that doctors must do whatever it takes before giving up. All patient deserve healthcare.
Nowadays, the DNR form endorsed does not serve its initial purpose to allow euthanasia (mercy killing) should the person has reached a point of no return. It has rather been misused by people who cannot endure further pain and want to give up. We can't really blame them for their inability to withstand suffering. After all, only those who feel it know how much it hurts...
