There was no apparent influence of the demographic data. This sample was only representative of Welsh people; hence no diversity of culture. The reports were, however, consistent with other documented British NDEs. It is apparent that NDEs are not wishful thinking as some experiences did not meet the expectations of the patient and two NDEs were unpleasant.
One of the most significant findings of this research was that the closer one comes to death, the more likely it is that a NDE will be reported. The total number of patients who survived ITU (not all of whom came close to death) were compared with cardiac arrest survivors (those who had been clinically dead for a period of time). It was discovered that there was a much higher frequency of NDEs among cardiac arrest survivors. In comparing heart rhythms among cardiac arrest survivors, it was also discovered that the rhythm most prevalent in the NDE group was asystole — a rhythm associated with the highest fatality.
None of the OBErs in this study viewed the hidden symbols placed on the monitors. However, this study has shown that one patient reported a very accurate OBE during a period of unconsciousness. The other OBErs also reported accurate descriptions but these were not verifiable and could have been viewed from their position in the bed.
When contrasted with the control group, who had undergone resuscitation but did not report an OBE, many discrepancies were discovered. Having been asked to re-enact their resuscitation, the control group’s reports were very inaccurate and demonstrated misconceptions and errors between the actual procedures performed, as well as equipment used. Many of these patients either had no idea as to how they had been resuscitated or made guesses, based on what they had previously seen on television.
