Advances in resuscitation science have indicated that, contrary to perception, death by cardiorespiratory criteria can no longer be considered a specific moment but rather a potentially reversible process that occurs after any severe illness or accident causes the heart, lungs, and brain to stop functioning. The resultant loss of vital signs of life (and life processes) is used to declare a specific time of death by physicians globally. When medical attempts are made to reverse this process, it…

Do out-of-body and near-death experiences point towards the reality of nonlocal consciousness? A critical evaluation
In recent years there was a steady flow of academic studies claiming that the mind or consciousness can function independently from a working brain. Such research is presented with great confidence

In the present chapter, death is considered from three different but complementary points of view: the diagnostic-medical which defines five formal stages from diagnosis to the palliative phase, the physical approach in terms of the characteristic symptoms, and the psychological approach, focusing on the meaningfulness of life.
Semiology and Mechanisms of Near-Death Experiences
Recent prospective studies confirm that NDEs reflect a spectrum of highly distinctive memories which are associated with negative or positive emotions and can be influenced by the nature of the causal event, but the temporal sequence with which these images unfold is variable.
Donation after brain circulation determination of death
In cases of circulatory cessation, such as occurs in DBCDD, death can be defined as the permanent cessation of brain functions, determined by the permanent stoppage of brain circulation.
Near-death experiences, posttraumatic growth, and life satisfaction among burn survivors
Survivors of large burns may face positive and negative psychological after-effects from close-to-death injuries and posttraumatic growth (PTG) and life satisfaction afterwards and social workers and other health providers need to be comfortable helping burn survivors discuss any NDEs and process these through survivors’ spirituality and religious belief systems as they recover.

Clinicians should be cautious of implementing recommendations that are grounded in consensus-based expert opinions particularly when recommendations contravene contemporary scientific evidence.

Abstract: Despite their different etiologies, three types of spiritually transformative experiences (STEs)--near-death experiences, psilocybin experiences, and meditative experiences of cosmic


Near-death experiences.
In a near death experience, the patient is clinically dead, but is then revived and able to describe what " death was like, yet the person was conscious, aware and watching as attempts were made to resuscitate him.
Childhood near-death experiences.
A neurophysiologic hypothesis as to the cause of NDEs is presented and it is suggested that a core NDE, triggered by the process of dying or resuscitation efforts, may be a natural developmental experience.

History of the Science of Cardiopulmonary Resuscitation
Through much of recorded history, resuscitation was forbidden. Although written accounts of resuscitation can be found, it is clear that successful reversal of death was thought to have been
