A heart remains viable for transplant for 4 to 6 hours after death, but new technology is extending this to 24 hours or more, allowing researchers to perfuse it with oxygen and nutrients to mimic the body, potentially revolutionizing organ donation by removing geographical limits. While the heart can beat briefly after blood flow stops, its functional life for transplantation is very short without immediate support.
For example, thoracic organs, like the heart and lungs, can only remain viable for transplant after being outside the body for four to six hours, while the liver can function for up to 12 hours and kidneys for up to 36 hours.
The brain and nerve cells require a constant supply of oxygen and will die within a few minutes, once you stop breathing. The next to go will be the heart, followed by the liver, then the kidneys and pancreas, which can last for about an hour. Skin, tendons, heart valves and corneas will still be alive after a day.
A widely discussed idea is that the brain may continue working for about seven minutes after death, potentially giving rise to vivid flashes of memory and awareness. Recent studies suggest this may not be just folklore.
The stages of death include: Pallor mortis: The main change that occurs is increased paleness because of the suspension of blood circulation. This is the first sign and occurs quickly, within 15-30 minutes of death.
Fear of Loss of Control
Human nature generally seeks to control the situations we encounter, but death remains something over which we have absolutely no control. This lack of control frightens many people.
For the first few minutes of the postmortem period, brain cells may survive. The heart can keep beating without its blood supply. A healthy liver continues breaking down alcohol. And if a technician strikes your thigh above the kneecap, your leg likely kicks, just as it did at your last reflex test with a physician.
A conscious dying person can know if they are on the verge of dying. Some feel immense pain for hours before dying, while others die in seconds. This awareness of approaching death is most pronounced in people with terminal conditions such as cancer.
Saying someone is your "seven minutes" means they are a significant, beautiful memory that you would want to experience one last time before you die, or a person whose memory is so important they would dominate your final moments.
During death, your body's vital functions stop entirely. Your heart no longer beats, your breath stops and your brain stops functioning. Studies suggest that brain activity may continue several minutes after a person has been declared dead.
You shouldn't fear death because it's a natural, inevitable part of life, and accepting its impermanence helps you focus on living fully in the present, find peace by letting go of attachments, or find hope in spiritual beliefs about an afterlife, with philosophies suggesting it's just the end of experience, making the fear itself pointless. Many find liberation in understanding that all things change and by focusing on leaving a positive legacy, as suggested by existentialists.
It takes around 12 hours for a human body to be cool to the touch and 24 hours to cool to the core. Rigor mortis commences after three hours and lasts until 36 hours after death.
Final stage (minutes before death).
In the last minutes of life, breathing becomes shallow and may stop altogether. The heartbeat slows and eventually ceases.
- *Hinduism*: Some Hindu texts suggest the spirit may linger near the body for up to 13 days after death. Scientific Perspective From a scientific standpoint, there's no empirical evidence to support the idea that the spirit or consciousness remains in the body after death.
How long will I have to wait to receive a transplant?
If brain death is confirmed, why does an individual's heart continue beating? As long as the heart has oxygen, it can continue to work. The ventilator provides enough oxygen to keep the heart beating for several hours.

“ Some scientists claim that the brain might be active for a short time after someone dies, maybe 7 minutes or more. They're not sure what happens during that time, if it's like a dream, seeing memories, or something else.
“Our data shows that a dying brain can respond to sound, even in an unconscious state, up to the last hours of life.”

Seriously ill patients encountered by hospice and palliative care clinicians are at risk for thirst due to dehydration, electrolyte disturbances, hypotension, xerostomia, and immobility which can impede access to water.
It's common to have fears about the process of dying. But many people say they worry about the unknowns of dying more than actually fearing death. Having some idea of what to expect can help some people. Not being prepared, or imagining what might happen, can be distressing for you and for your family and friends too.
The hardest deaths to grieve often involve a child, a spouse/life partner, or a loss due to suicide or homicide, as these challenge fundamental beliefs about life's order, shatter primary support systems, or add layers of trauma, guilt, and unanswered questions, leading to potentially complicated grief.
