However, euthanasia must be distinguished from the stopping of extraordinary means of health care or other aggressive medical treatment. The patient — or guardian in the case of an unconscious patient — has the right to reject outright or to discontinue those procedures which are extraordinary, no longer correspond to the real situation of the patient, do not offer a proportionate good, do not offer reasonable hope of benefit, impose excessive burdens on the patient and his family, or are simply "heroic." Such a decision is most appropriate when death is clearly imminent and inevitable. Here a person may refuse forms of treatment which at best provide a precarious and burdensome prolonging of life. In these cases, the person would place himself in God's hands and prepare to leave this life, while maintaining ordinary means of health care.
