Your brain stops. Other vital organs, including your kidneys and liver, stop. All your body systems powered by these organs shut down, too, so that they're no longer capable of carrying on the ongoing processes understood as, simply, living. Death itself is a process.
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.
The heart is the last organ to fail.
As organs begin to shut down, most people experience drowsiness and may gradually lose consciousness. Eventually the heart and lungs will stop working and the body dies. Breathing patterns change. A person may breathe more slowly or more quickly.
There are three main stages of dying: the early stage, the middle stage, and the last stage. These are marked by various changes in responsiveness and functioning. However, it is important to keep mind that the timing of each stage and the symptoms experienced can vary from person to person.
Sometimes the breathing may be fast, and at other times there may be long gaps between breaths. Breathing may be shallow or noisy. This, too, is due to blood circulation slowing down and a build up in the body's waste products. It is not painful or distressing for the person.
The first organ system to “close down” is the digestive system. Digestion is a lot of work! In the last few weeks, there is really no need to process food to build new cells.
Periods of rapid breathing, and no breathing for brief periods of time, coughing or noisy breaths, or increasingly shallow respirations, especially in final hours or days of life.
What happens when someone dies? In time, the heart stops and they stop breathing. Within a few minutes, their brain stops functioning entirely and their skin starts to cool.
Hearing is widely thought to be the last sense to go in the dying process. Now, the first study to investigate hearing in palliative care patients who are close to death provides evidence that some may still be able to hear while in an unresponsive state.
One of the wildest innovations is “living funerals.” You can attend a dry run of your own funeral, complete with casket, mourners, funeral procession, etc. You can witness the lavish proceedings without having an “out-of-body” experience, just an “out-of-disposable-income” experience.
These results provide insight into the observation that the uterus and prostate are the last internal organs to decay during human decomposition.
Gasping is also referred to as agonal respiration and the name is appropriate because the gasping respirations appear uncomfortable, causing concern that the patient is dyspnoeic and in agony.
As the moment of death comes nearer, breathing usually slows down and becomes irregular. It might stop and then start again or there might be long pauses or stops between breaths . This is known as Cheyne-Stokes breathing. This can last for a short time or long time before breathing finally stops.
Anticipatory medicines are sometimes also called end of life medicines or just in case medicines. It's common to prescribe medicine for pain, anxiety and agitation, nausea and vomiting and noisy respiratory secretions.
“First hunger and then thirst are lost. Speech is lost next, followed by vision. The last senses to go are usually hearing and touch.”
The stages of the Kubler-Ross theory include denial, anger, bargaining, depression, and acceptance.
They might close their eyes frequently or they might be half-open. Facial muscles may relax and the jaw can drop. Skin can become very pale. Breathing can alternate between loud rasping breaths and quiet breathing.
The end-of-life period—when body systems shut down and death is imminent—typically lasts from a matter of days to a couple of weeks. Some patients die gently and tranquilly, while others seem to fight the inevitable. Reassuring your loved one it is okay to die can help both of you through this process.
It depends on the organ. For now, the time window can be between 4 and 36 hours. But someday, doctors hope to be able to maintain organs for weeks on end.
