In the United States death is determined upon EITHER the irreversible cessation of cardiopulmonary function or the irreversible cessation of all brain function.
But how exactly is “irreversible cessation” measured There are growing calls to amend the prevailing standards and criteria for determining brain death and circulatory death.
On determining irreversible cessation of brain function, the Aden Hailu case now being briefed to the Nevada Supreme Court contends that the most commonly (though not universally) used criteria should be changed.
On determining irreversible cessation of cardiopulmonary function, two Australian researchers just argued that we should omit the requirement for irreversibility in the definition of circulatory death and redefine it as “cessation of circulatory function with cessation of higher brain function.”
