A rationale in support of uncontrolled donation after circulatory determination of death.

In the United States, when people die unexpectedly, they are usually not considered as organ donors because of the difficulty of keeping organs viable when death occurs outside the hospital, in "uncontrolled" circumstances. New protocols to permit donation in these cases have renewed the debate about how we decide whether a person has died- and whether the moral imperative to help those in need of transplant should affect the determination of death.
