Each time patients and their families are asked to make a decision about resuscitation, they are also asked to engage the political, social, and cultural concerns that have shaped its history. That history is exemplified in the career of Claude S. Beck, arguably the most influential researcher and teacher of resuscitation in the twentieth century. Careful review of Beck’s work discloses that the development and popularization of the techniques of resuscitation proceeded through a multiplication of definitions of death. CPR consequently (...) remains unique among medical treatments, because it is indicated precisely when a person dies, depending always on how each event of death becomes defined practically by patients, families, and medical professionals present at the time. It is therefore as an occasion to manage a surplus of definitions of death, and not as an occasion to determine the physiological efficacy of resuscitation, that one should approach analysis of contemporary challenges in decision-making about resuscitation.
