7 minutes after death : You're alive
In March, doctors in a Canadian intensive care unit found that a person had sustained brain activity for seven minutes after turning off his life support machine. Even after medics declared the person clinically dead, brain waves continued to occur as if in sleep. The researchers also found that the experience of death can vary widely among individual patients.
The most important next step for scientists is to find ways to monitor the brain on the brink of death, improve the quality of resuscitation and better prevent brain damage after a restart of the heart, Parnia said. Researchers in the study also monitored the brain for seven minutes to understand how much oxygen gets into the brain when the cortex is back online and how the experience is related to brain activity itself, he added. After death, patients recorded the same activity in the cerebral cortex and other parts of the body.
The flatliner films also suggest that reviving death can increase normal brain activity, just as a student who dies and wakes up suddenly can recall obscure passages from a long-forgotten book.
The new study suggests that a person's consciousness can continue to work even after their heart has stopped beating and their body's movements have failed. In the real world, Parnia said, the return ticket from death often includes newly acquired cerebral superpowers, which often offer a new perspective on life.
The study shows that cardiac arrest survivors are able to die again while they are dead, including the doctors who try to save them and listen to their conversations, and be brought back to life. This means that a dead body can be trapped in a state of consciousness, even if the brain is still functioning for a short time. This means that a person may even hear doctors announce their death, essentially trapping their body and brain function in their body.
Even more shocking is that there is evidence that the deceased may even be declared dead by doctors themselves. The study shows that cardiac arrest survivors can return to life while they are dead.
Dr. Sam Parnia has studied post-death awareness and investigated cases of cardiac arrest in Europe and the United States (quotation required). Scientific studies have shown that brain death is defined by the cessation of brain activity within 7 minutes of death. Consciousness and death are a common theme in society and culture in the context of the afterlife.
Many, however, believe in an afterlife that occurs in many religions. The vast majority of deaths occur after cardiopulmonary abstinence, which also ends brain function.
Brain death may be a determining factor, but clinical diagnosis is not simplified, and biological processes can persist even after the brain stops. It is unusual to determine neurological death in intensive care units, where patients with severe brain injuries are typically admitted after an opioid overdose.
In fact, a brain - a dead body - can be kept alive for hours, or all day, or even weeks, or months after death.
In medicine, the activity of the entire brain, including the brain stem, in a patient on life support is called brain death. The diagnosis of "brain death" is made after a brain reveals its true state because it has no access to oxygen or nutrients. In order to diagnose brain death in patients with cardiac death (stopped heart), it is necessary to first restart the blood circulation and perform neurological tests many hours later.
It is true that a patient whose normal body temperature is without oxygen for minutes and who is then resuscitated is likely to be diagnosed brain dead the next day.
Canadian doctors in intensive care seem to have observed that a person's brain continues to function even after clinical death. In this case, doctors confirmed that their patient was dead after normal observations, including the absence of a pulse and unreactive pupils. However, brain activity stopped seven minutes after the body appeared to have died.
Tests showed that the patient's brain appeared to continue to function and experienced the same brain currents as in deep sleep. Many of the known electrical signatures of consciousness exceeded the values found in waking states, suggesting that the brain is capable of well-organized electrical activity in the early stages of clinical death. A recent study found that rats showed a similar pattern of activity in their brains seven minutes after a human died.
The brain showed that the low gamma waves produced during the early stages of consciousness, such as the first few minutes after death, became stronger during this short period of time. This suggests that our final journey into permanent unconsciousness may indeed involve a short state of heightened consciousness and memory.
