As new advances in engineering have occurred in the past quarter century, new ethical issues have arisen, as we frequently see in health care technology. The health care industry can now keep many people alive for a longer period of time, and people who would have died twenty‑five years ago can now be treated. Premature infants, heart attack victims, and other individuals can now be treated with new devices that prolong life. But new possibilities also raise ethical questions about who should receive benefits, who should pay for them, and when is it ethical to prolong life. Should a person who is being kept alive on by a machine and who has no chance of being returned to a state of health be permitted to die? At what birth weight should a premature infant be treated with unusually expensive equipment? Learning how to deal with ethical issues will be an important part of your engineering career. This summary can only touch the surface of the issues that lie ahead.
