KIE: This report represents a consensus of the individual physicians who served as consultants to the President's Commission; it has not been passed on by the Commission. It provides a statement of currently accepted medical criteria that could be used in implementing the proposed Uniform Determination of Death Act. The criteria are designed to help a physician determine if death has occurred, with no error in classifying a living individual as dead and with as few errors as possible in classifying a dead body as alive.
