THE PROBLEM OFIRREVERSIBILITYFor an individual to be deadby this definition, thestoppage of bodily integrative function such ascirculatory and respiratory function must beirreversibleIt is very common but very wrong for clinicians andothers to refer to someone who has suffered a cardiacarrest and been successfully resuscitated as havingbeen “clinically dead.” Being dead means irreversibleloss of circulatory function

CASE 3: THE MAN LIVING WITHOUT A

HEART

Some year ago, a dentist named Barney Clarke was a heart patient at

the University of Utah, where clinicians were experimenting with

artificial hearts. Since he was at death’s door and awaiting a heart

transplant, the physiciansremoved his heart and connected his aorta

and veins back up to a Jarvik-7 artificial heart pump. Barney Clarke

lived for four months on that artificial heart. At times he was

doing quite well with this machine running next to him, pumping like

a heart would pump blood. At times he would sit up in bed, even get

out of bed and go for a stroll, pulling this machine along with him

on a cart. If he is carrying on a conversation, smiling, and

discussing things with those at his side, would anyone, even

believers in a definition of death focusing on heart function,

consider him dead?
