In the hours before death, most people fade as the blood supply to their body declines further. They sleep a lot, their breathing becomes very irregular, and their skin becomes cool to the touch. Those who do not lose consciousness in the days before death usually do so in the hours before.
Dying is a natural process that the body has to work at. Just as a woman in labor knows a baby is coming, a dying person may instinctively know death is near. Even if your loved one doesn't discuss their death, they most likely know it is coming.
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.
The signs and symptoms of active dying include: Long pauses in breathing; patient's breathing patterns may also be very irregular. Blood pressure drops significantly. Patient's skin changes color (mottling) and their extremities may feel cold to the touch.
For some people, the dying process may last weeks; for others, it may last a few days or hours.
End-of-life transition refers to a person's journey to death, especially in those with a terminal diagnosis. This process occurs differently for everyone. For some, it takes days or weeks; for others, it occurs rapidly. Partnering with a trusted medical team during this time can limit pain.
The heart and lungs are generally the last organs to shut down when you die. The heartbeat and breathing patterns become irregular as they progressively slow down and fade away.
Changing vital signs
As a person approaches death, their vital signs may change in the following ways: blood pressure drops. breathing changes. heartbeat becomes irregular.
You'll start to feel more tired and drowsy, and have less energy. You'll probably spend more time sleeping, and as time goes on you'll slip in and out of consciousness.
As the end of life nears, the body gradually loses its ability to digest and process foods and liquids. As organs and bodily functions shut down, minimal amounts of nutrition or hydration/liquids might be needed, if at all.
You might be unable to stop crying and worrying. Or you might feel that there is no point in doing anything. You might also find it difficult to see life going on as normal for most people. It can feel very strange to watch people go about their daily lives, do shopping, drive, and work.
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.
People often become more drowsy and sleep more towards the end of life. This is one of many signs that a person may have when they are in their last few days and hours of life, but not everyone will experience this.
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.
In fact, medical researchers believe that the phenomenon—which is commonly called a death rattle—probably doesn't hurt. Ultimately, because most people lose awareness or consciousness in their last few hours or days, it's hard to know for certain how much they're suffering.
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.
Agonal breathing or agonal gasps are the last reflexes of the dying brain. They are generally viewed as a sign of death, and can happen after the heart has stopped beating.
Increased need for medication due to uncontrolled pain or symptoms. Shortness of breath. Difficulties performing the tasks of daily living: bathing, getting out of bed, getting dressed, walking, or preparing and eating meals. Increased number of trips to the ER and multiple hospitalizations.
Although it can include end of life care, palliative care is much broader and can last for longer. Having palliative care doesn't necessarily mean that you're likely to die soon – some people have palliative care for years. End of life care offers treatment and support for people who are near the end of their life.
