I haven't studied it in-depth, but it does seem to regard the near-death experience as a unique form of consciousness. A number of patients were interviewed in a clinical setting for this study, and researchers recorded a number of brief observations similar (in some respects) to those made the self-selected experiencers who publish on Internet forums like NDERF.org.
(Hypothetical question: would an ND experiencer be more inclined to tell the "whole story" in a clinical setting to a trained observer, or on a semi-open forum that is perceived as being more "welcoming"? Or, are the majority of NDERF.org respondents embellishing and confabulating their accounts?)
The most interesting observation--to me--is this:
The finding that conscious awareness may be present during CA is intriguing and supports other recent studies that have indicated consciousness may be present in patients despite clinically undetectable consciousness.
The reason that it interests me is that in a large number of NDE accounts, cardiac arrest is the trigger that launches consciousness from the body, something that the researchers seem to implicitly recognize. It serves as a boundary between physical and non-physical consciousness. In plain English, the study is admitting that "CA patients really are conscious, even though we can't measure this with our instruments."
