One man, however, gave a “very credible” account of what was going on while doctors and nurses tried to bring him back to life – and says that he felt he was observing his resuscitation from the corner of the room.
Speaking to The Telegraph about the evidence provided by a 57-year-old social worker Southampton, Dr Parnia said: “We know the brain can’t function when the heart has stopped beating.
“But in this case, conscious awareness appears to have continued for up to three minutes.
“The man described everything that had happened in the room, but importantly, he heard two bleeps from a machine that makes a noise at three minute intervals. So we could time how long the experienced lasted for.
“He seemed very credible and everything that he said had happened to him had actually happened.”
Dr Parnia’s study involved
2,060 patients from 15 hospitals in the UK, US and Austria, and has been published in the journal Resuscitation.
