New York . One in five people who survive cardiopulmonary resuscitation (CPR) after cardiac arrest can describe near-death experiences when they were unconscious and on the verge of death. This has come out from a study. The study, led by researchers from New York University’s Grossman School of Medicine and elsewhere, involved 567 men and women whose hearts stopped beating during hospitalization.
Survivors recounted their experiences during cardiac arrest. This includes the experience of detachment from the body, the observation of events without pain or discomfort, and a meaningful appraisal of life, including their actions, intentions, and thoughts toward others.
The researchers found these near-death experiences to be distinct from hallucinations, delusions, dreams, or consciousness from CPR.
Sam Pernia, chief of the department of medicine at NYU Langone Health, said that recalled experiences and brain wave changes may be early signs of so-called near death.
Pernia said in a study published in the journal, “Our results are evidence that people on the verge of death and in coma go through a unique inner conscious experience without any discomfort.”
An important finding was the detection of spikes of brain activity, including so-called gamma, delta, theta, alpha and beta waves, for up to an hour in CPR.
Some of these brain waves typically occur when people are conscious and have high levels of mental function, including thinking, memory retrieval, and conscious perception.
The survey findings suggest that the human sense of self and consciousness, like other biological functions of the body, may not be completely shut off at the time of death.
Parnia said that these experiences cannot be considered a disordered or dying brain trick, but a unique human experience that emerges on the verge of death.
He said it clearly raises interesting questions about human consciousness.
