Currently, there is no drug or therapy that can reverse organ failure. However, organ function can recover to some degree. Doctors have discovered that some organs recover better than others. Multiple organ failure recovery can be a slow and challenging process.
In most people who are dying, the body's normal systems start to operate more slowly. The heart beats a little more slowly, or with a little less force, and so blood is moved around the body more slowly. This means the brain and the other organs receive less oxygen than they need, and do not function as well.
Decompensation progresses over a period of minutes even after the pulse is lost. Even when vascular collapse is the primary event, brain and lung functions stops next. The heart is the last organ to fail.
Chronic organ failure is sometimes reversible in the early stages if you're able to treat the original cause effectively. However, the later stages are generally marked by irreversible damage, such as fibrosis (scarring in your organs) or tissue death.
When a person is brain dead, or no longer has brain activity, they are clinically dead. Physiological death may take 72 or fewer 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.
Acute kidney failure can be fatal and requires intensive treatment.
Generally, the lung is the first organ to fail after injury (failure after 3.7 +/- 2.8 days). Significant renal failure and the need for dialysis decreased to < 5%; other signs of organ dysfunction (gastric, central nervous system) are difficult to verify.
The patient's kidneys gradually lose their ability to filter waste and extra water from the blood, creating a build-up within the body, which is terminal when left untreated.
Visions and Hallucinations
Visual or auditory hallucinations are often part of the dying experience. The appearance of family members or loved ones who have died is common. These visions are considered normal. The dying may turn their focus to “another world” and talk to people or see things that others do not see.

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.
In most cases, when a patient is receiving the care and support of hospice, they will not experience pain during the dying process. Instead, their body will naturally begin to shut down. They will begin to have a decreased desire to eat and drink and will start to sleep more.
No matter the cause of death - cancer, heart disease, or other organs shutting down - the experience can be frightening and painful for both parties.
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.
Without dialysis or a kidney transplant, kidney failure is fatal. You may survive a few days or weeks without treatment. If you're on dialysis, the average life expectancy is five to 10 years.
postulated that mechanical ventilation induces pulmonary production of inflammatory mediators, which exacerbate lung injury. Moreover, they suggested that overspill of these mediators into the systemic circulation of patients could contribute to multiple organ failure.
Sepsis can overwhelm the body. This can cause vital organs to shut down. This usually starts with the kidneys. Blood pressure can drop dangerously low.
In the last few days of life, symptoms of advanced or end-stage kidney failure include: pain – for example, a headache or bone pain. agitation. itch due to uraemia (a build-up of toxins in the blood due to kidney failure)
Dying from sepsis is a painful event since patients with sepsis shock can die within hours or days if they don't receive immediate medical attention and proper treatment. Patients who are older tend to have more painful deaths because they are more likely to have: Repeated exposure to an infectious agent.
Overview. End-stage renal failure, also known as end-stage renal disease (ESRD), is the final, permanent stage of chronic kidney disease, where kidney function has declined to the point that the kidneys can no longer function on their own.
The brain lives on for 30 seconds after death.
Although death has historically been medically defined as the moment when the heart irreversibly stops beating, recent studies have suggested brain activity in many animals and humans can continue for seconds to hours.
After death, there is are no reflexes of the pupils to light and the cornea also loses its reflex. The cornea of the deceased also become cloudy after two hours of death. Besides that, the pressure in the eyes start to decrease and the eyeballs become flaccid before it they sink into the orbits of the eyes.
