This article examines life-extending technologies such as resuscitation, mechanical ventilation, antibiotics, dialysis, and artificial nutrition and hydration. It considers these technologies in terms of the value issues of (1) equity of access, (2) equity of allocation, (3) cost-effectiveness and appropriateness of use, (4) legal concerns, and (5) determination and control of the application of technology. How we resolve these issues tests our character as individuals and as a society--it plays a key role in determining who shall live and what kind of society we shall become.
