The AWARE Studies: One Patient and a Thousand Shelves

Anecdotes are always open to the charge that memory and retelling did the work. The AWARE project, led by the resuscitation researcher Sam Parnia, was meant to fix that: interview cardiac arrest survivors soon after the event, using standard questions, and place images in resuscitation areas that could be seen only from near the ceiling. If anyone really left their body and looked down, they could be asked what the picture was.

The claim

At least one patient in the first AWARE study was consciously aware, and accurately perceived his own resuscitation, for several minutes after his heart stopped, a time when the brain is not expected to support consciousness. Some take this as the first objective, prospectively recorded evidence of perception during clinical death.

What was documented, when, by whom

AWARE (2014). Parnia et al., "AWARE: AWAreness during REsuscitation, a prospective study", Resuscitation 85(12) (2014), 1799 to 1805. The study ran at 15 hospitals in the UK, USA and Austria. Each site installed between 50 and 100 shelves, each holding a single image facing the ceiling. Of 2,060 cardiac arrests, 140 survivors completed first-stage interviews and 101 completed detailed ones. Forty-six per cent had memories of some kind, 9 per cent had NDEs, and 2 per cent "described awareness with explicit recall of 'seeing' and 'hearing' actual events related to their resuscitation". The abstract adds: "One had a verifiable period of conscious awareness during which time cerebral function was not expected."

That patient was a 57-year-old man. He described an automated voice saying "shock the patient", which matches an automated external defibrillator, and a man in blue scrubs and a blue hat, whose presence and role the team confirmed from the records. He also described a woman beckoning him from a corner of the room. Parnia told the Daily Telegraph that the man recalled two bleeps from a machine that sounds at three-minute intervals, which let the team estimate that his awareness lasted up to about three minutes into the arrest.

His arrest did not happen in a room with a shelf. According to the Psi Encyclopedia's summary of the study, about 78 per cent of the arrests occurred in areas without shelves, and no survivor identified an image.

AWARE II (2023). Parnia et al., "AWAreness during REsuscitation - II: A multi-center study of consciousness and awareness in cardiac arrest" (Resuscitation 191, 2023, article 109903) moved the target onto a tablet placed above the patient during CPR, added an audio stimulus through headphones, and recorded EEG and brain oxygen in real time. Of 567 in-hospital arrests at 25 sites, 53 patients survived and 28 were interviewed. Eleven reported memories or perceptions suggesting consciousness. The abstract's verdict on the tests is short: "Nobody identified the visual image, 1/28 (3.5%) identified the auditory stimulus." It also reports that, despite very low brain oxygen, normal EEG activity "consistent with consciousness emerged as long as 35-60 minutes into CPR".

Why it's cited

This is the closest the field has come to doing it properly: many hospitals, consecutive patients, standard interviews, and medical records to check against. The 57-year-old man's account was taken prospectively and checked by the team, not by an enthusiast years later. Parnia himself framed it cautiously, as one credible case rather than proof.

The skeptical case

Everything verified in the man's account was auditory or generic. An AED announces its instructions out loud. A person in blue scrubs and a hat is what a hospital resuscitation looks like. He reported nothing that required a view from above, and there was no image in his room to test him. The timing comes from his memory of two bleeps, not from a brain recording, and no EEG was taken.

The neurologist Steven Novella argued when the paper appeared that memories like this are more likely formed as the brain recovers than during the arrest itself. A second ordinary possibility is a brief return of awareness during the resuscitation, and AWARE II supports it in an unexpected way: it found that brain activity compatible with consciousness can return during CPR, sometimes long into it. That makes "aware during the resuscitation" plausible, but through a working brain, not without one.

Then there are the targets. Across both studies, roughly a thousand shelves and a tablet placed directly above the patient, the visual tests produced no hits at all. The one auditory hit in AWARE II is consistent with ordinary hearing, which no one disputes can survive deep unconsciousness.

Status

AWARE produced the most carefully documented single case of awareness during cardiac arrest, and it moved the debate toward measurement. It did not produce visual perception from outside the body, and its sequel made a brain-based explanation for awareness during CPR more plausible, not less. Rating: Moderate for the patient; the target tests are a negative result.
