Is consent useful when resuscitation isn't?

A Do Not Resuscitate order reflects a considered judgment that a physician can no longer stave off death. Why, then, have a patient consent to such an order? The primary point is that physicians should share with patients their judgment about what medicine can and cannot do. Because we cannot make death go away, we must make decisions about when to withhold or limit resuscitation openly, in honest and trusting conversation between doctor and patient.
