When a person is dying,what is the feeling?This is definitely one of the most common questions among living human beings.The good thing is that the question has been answered. Below is an article explaining step by step on how a person feels like when they are dying!
Scientists reported in October 2017 that they had discovered a person’s consciousness continues to work after the body has stopped showing signs of life.
That means they may be aware of their own death and there is evidence to suggest someone who has died may even hear their own death being announced by medics. For close to 30 minutes, when people are mourning and touching the body, the person is aware of what’s going on.
A team from New York University Langone School of Medicine investigated the topic through twin studies in Europe and the US of people who have suffered cardiac arrest and ‘come back’ to life, in the largest study of its kind.
Study author Dr Sam Parnia told Live Science: ‘They’ll describe watching doctors and nurses working and they’ll describe having awareness of full conversations, of visual things that were going on, that would otherwise not be known to them.’
He said these recollections were then verified by medical and nursing staff who reported their patients, who were technically dead, could remember details of what they were saying.
Doctors define death based on when the heart no longer beats, which then immediately cuts off blood supply to the brain.
Once that happens, blood no longer circulates to the brain, which means brain function halts almost instantaneously.
You lose all your brain stem reflexes, including your gag reflex and your pupil reflex.
The brain’s cerebral cortex, which is responsible for thinking and processing information from the five senses, also instantly flatlines.
This means that within two to 20 seconds, no brainwaves will be detected on an electric monitor.
This sparks a chain reaction of cellular processes that will result in the death of brain cells.
However this can take hours after the heart has stopped, researchers said.
The findings suggest old age decline is linked to cells’ weakening ability to generate energy in the form of ATP.
Without this energy, the cells can’t hold calcium in the muscle, causing it to flood out and trigger necrosis.
‘Dying C. elegans also undergo what we term a “belly punch” phenomenon where death contraction in the head drives the pharynx backwards into the intestine, and the impact triggers cell death,’ said Professor Gems.
‘Discovering rigor mortis in worms is exciting as it highlights a key step in the chain of events leading from healthy adulthood to death from old age,’ Gems said.
‘It helps us to understand death in humans, and perhaps in the future to prevent death in mortally ill patients.’
