IAN: Interesting. Indeed, that's virtually indicated because
it is the existence of oxygen that prevents sudden and massive
damage resulting from hypoxia. Therefore, if the brains survived
intact, it tends to follow that they weren't oxygen deprived, and
moreover that they therefore were never brain dead. What's really
amazing is that the media reports state that there was "no brain
activity" in patients. However, I cannot find any such statements
in the actual study. In fact, the criteria for "clinical death"
is stated as such: "We defined clinical death as a period of
unconsciousness caused by insufficient blood supply to the brain
because of inadequate blood circulation, breathing, or both."
See the sections "procedures" and "patients" for this and more.
Media reports lead us to believe that brain-activity measures
were recorded by some means, but that is not the case. All that
the study did was determine that a patient had cardiac arrest,
ie, their heart stopped, for some time during which they were
unconscious, or "clinically dead." So the media claims of "no
brain activity" are an extrapolation without direct evidence.
And even if we assume the patients were brain dead for some
period, there is the problem of proving that the NDEs occurred
at the same time that there was no brain activity. Yet all the
study did was ask people after they were resuscitated if they
remember any NDE-like events, which could have occurred at any
time during their cardiac event. The study is seriously flawed
relative to the extraordinary conclusions being derived from it.
