In this Article, which draws primarily on continental West European views on death and dying, the author contends that the Harvard criteria for irreversible coma (1968) are not reliable for diagnosing death in comatose patients under resuscitation treatment. The Article suggests that use of the Harvard Criteria to diagnose death leaves such patients legally unprotected against surgical assaults such as organ removal and biomedical experiments while they still may be living and capable of perception, possibly including the perception of pain and the spoken word. An alternative to the Harvard Criteria—angiography—is offered, and several additional issues related to the definition and diagnosis of death are discussed. Finally, the author suggests that even prior to death, termination of resuscitation treatment of irreversibly comatose patients, though followed by death, should be lawful.
