Thus, if a patient has suffered brain damage to such an extent that survival will not include the ability to lead a life even approximating the normal, or if the disease processes in a patient have debilitated the patient beyond any hoipeful prognosis, it is very likely that a consideration of all of the circumstances of the individual case will lead to the sound moral judgment that artificial resuscitation, whether manual or mechanical, may be considered in that particular case to be a relatively extraordinary means of prolonging life. Once this judgment is reached, then the wishes of the patient become the operative norm for further treatment.
