Near-death experiences: only oxygen deficiency in the brain? Through research at three of the country's largest Slovenian hospitals, Slovenian researchers attribute the near-death experiences of resuscitated people to the high proportion of carbon dioxide in those affected.

The researchers Zalika Klemenc-Ketis, Stefek Grmec and Janko Kersnik from the University of Maribor successfully examined the effect of the partial pressure of oxygen (O2) and carbon dioxide (Co2) and the serum values ​​of sodium (Na) and potassium (K) on 52 resuscitated patients, with an average age of 53.1 years. 42 of the resuscitated patients were men.

Near-death experience (NDE) was reported by 11 of those involved, which is around 21 percent. A near-death experience (NDE) is called an experience that occurs in people with a short-term cardiac arrest. Affected people often report hovering above the site and lights at the end of a tunnel.

An increase in Co2 and potassium levels in the blood of people with cardiac arrest occurs within minutes. These values, especially the increased Co2 content (hypercapnia), were related to increased near-death experiences. Carbon dioxide changes certain metabolic processes in the brain and, according to the scientists, is said to be responsible for the events reported later.

The term thanatology describes a science, among other things, of near-death experiences. A well-known representative is the Swiss doctor Elisabeth Kübler-Ross (1926-2004). She is considered to be the founder of dying research, but has incorporated her own interpretations very strongly into her work. (Thorsten Fischer, naturopath osteopathy, April 9th, 2010)
