Being cold is one of the factors that slows down the rate of cellular decay.
Intriguingly, this process is something that can now be manipulated through medical intervention. This is consistent with a mounting understanding: it is only after a person actually dies that the cells in the body start to undergo their own process of death. What has become increasingly clear is that the apparent irreversibility of death as we know it may not necessarily reflect true irretrievable cellular damage inside the body. Either way, the brain dies hours or possibly longer after these injuries have taken place and not just minutes. This is because the brain can die either from oxygen starvation after cardiac arrest or from massive trauma and internal bleeding. These people can be legally declared dead based on brain death criteria before their hearts have stopped. The only exception is the small proportion of people who may have suffered catastrophic brain injuries, but whose hearts can be artificially kept beating for a period of time on life-support machines. This is how roughly 95 percent of the population are declared dead. What was once called death-the ultimate end point- was now widely called cardiac arrest, and became a starting point.įrom then on, it was only if somebody had requested not to be resuscitated or when CPR was deemed to have failed that people would be declared dead by "cardiopulmonary criteria." Biologically, cardiac arrest and death by cardiopulmonary criteria are the same process, albeit marked at different points in time depending on when a declaration of death is made.Ĭlearly, contrary to many people's perceptions, cardiac arrest is not a heart attack it is the final step in death irrespective of cause, whether it be a stroke, a heart attack, a car accident, an overwhelming infection or cancer.
The advent of cardiopulmonary resuscitation (CPR) in the 1960s was revolutionary, demonstrating that the heart could potentially be restarted after it had stopped, and what had been a clear black-and-white line was shown to be potentially reversible in some people. The law, for example, relies on "time of death," which corresponds to when the heart stops beating. Since the cessation of the heart literally occurs in a "moment," the philosophical notion of a specific point in time of "irreversible" death still pervades society today. Consequently, within seconds, breathing stops and brain activity comes to a halt. This is because once the heart stops beating, blood flow stops and oxygen is cut off from all the body's organs, including the brain. A person became motionless, lifeless, and was deemed irreversibly dead. Throughout history, the boundary between life and death was marked by the moment a person's heart stopped, breathing ceased, and brain function shut down. It is a testament to the incredible impact of resuscitation science - a science that is providing opportunities to literally reverse death, and in doing so, shedding light on the age-old question of what happens when we die. Interestingly, this man represents one of a growing number of extraordinary cases in which people who would otherwise be declared dead have now been revived. The medical team who revived him were reported as being "stupefied" that they had been able to bring him back to life, in particular since he had not even suffered brain damage. For example, if the cat was attacking you, this might suggest that you're feeling attacked by some circumstance of your life.This was thought to have been possible in part because his body had progressively cooled down naturally after his heart had stopped, through exposure to the outside cold. If the cat was causing you to feel afraid, perhaps there is something in your life that's causing you fear or worry.Was the cat familiar to you, in the dream? Whether or not you recognize the cat from your waking life, you may experience a sense of familiarity to the cat in your dream.This might mean that help comes from unexpected places or people. For example, if you remember drowning, then being rescued by a cat, you might be filled with surprise and gratitude. To better understand your feeling about the cat in your dream, think about other dream elements you might remember.Were you happy to see the cat? Did the cat fill you with fear? Consider why this feeling might have come up for you. The feeling you had about the cat in your dream may tell you more about what the cat meant than any dream dictionary. Recall the feeling you had while dreaming.
