A Q & A about CPR on a first aid website doesn't compare to a peer-reviewed study with over 31 contributors.
Here is an exact quote from the paper:
(my bold) The results of the study do not support your uncritical acceptance of the defunct narrative about NDEs being the result of oxygen deprivation and hallucinations.
Here is an exact quote from the paper:
Quote:While some investigators have hypothesized there may be a brief surge of electrical activity after cardiac standstill, in contrast to anesthesia typically there is no measurable brain function within seconds after cardiac standstill. This ‘flatlined’ isoelectric brain state which occurs with CA [cardiac arrest] onset usually continues throughout CPR since insufficient cerebral blood flow (CBF) is achieved to meet cerebral metabolic requirements during conventional CPR. However it was estimated our patient maintained awareness for a number of minutes into CA. While certain deep coma states may lead to a selective absence of cortical electrical activity in the presence of deeper brain activity, this seems unlikely during CA as this condition is associated with global rather than selective cortical hypoperfusion as evidenced by the loss of brain stem function. Thus, within a model that assumes a causative relationship between cortical activity and consciousness the occurrence of mental processes and the ability to accurately describe events during CA as occurred in our verified case of VA when cerebral function is ordinarily absent or at best severely impaired is perplexing. This is particularly the case as reductions in CBF typically lead to delirium followed by coma, rather than an accurate and lucid mental state.

That's not impressive.

That makes you as blatantly anti-science as any young earth creationist. Worse actually.
