Email Predicting the death of a patient, even an elderly, demented one, is an inexact science, even for a doctor with decades of medical experience.

For example, brain death, as practiced in medical science, defines death as a point in time at which brain activity ceases.
As a point in time, death would seem to refer to the moment at which life ends. Determining when death has occurred is difficult, as cessation of life functions is often not simultaneous across organ systems. This is difficult, due to there being little consensus on how to define life.
This general problem applies to the particular challenge of defining death in the context of medicine. It is possible to define life in terms of consciousness. When consciousness ceases, a living organism can be said to have died. One of the flaws in this approach is that there are many organisms which are alive but probably not conscious for example, single-celled organisms.
Another problem is in defining consciousness, which has many different definitions given by modern scientists, psychologists and philosophers. Additionally, many religious traditions, including Abrahamic and Dharmic traditions, hold that death does not or may not entail the end of consciousness.
In certain cultures, death is more of a process than a single event. It implies a slow shift from one spiritual state to another. Thus, the definition of "life" simultaneously defines death.
Death was once defined as the cessation of heartbeat cardiac arrest and of breathingbut the development of CPR and prompt defibrillation have rendered that definition inadequate because breathing and heartbeat can sometimes be restarted.
Events which were causally linked to death in the past no longer kill in all circumstances; without a functioning heart or lungs, life can sometimes be sustained with a combination of life support devices, organ transplants and artificial pacemakers.
Today, where a definition of the moment of death is required, doctors and coroners usually turn to "brain death" or "biological death" to define a person as being dead; people are considered dead when the electrical activity in their brain ceases.
It is presumed that an end of electrical activity indicates the end of consciousness. Suspension of consciousness must be permanent, and not transient, as occurs during certain sleep stages, and especially a coma.
In the case of sleep, EEGs can easily tell the difference. The category of "brain death" is seen as problematic by some scholars. These patients maintained the ability to sustain circulation and respiration, control temperature, excrete wastes, heal wounds, fight infections and, most dramatically, to gestate fetuses in the case of pregnant "brain-dead" women.
Eventually it is possible that the criterion for death will be the permanent and irreversible loss of cognitive function, as evidenced by the death of the cerebral cortex. All hope of recovering human thought and personality is then gone given current and foreseeable medical technology.
Inthe Terri Schiavo case brought the question of brain death and artificial sustenance to the front of American politics. Even by whole-brain criteria, the determination of brain death can be complicated. EEGs can detect spurious electrical impulses, while certain drugshypoglycemiahypoxiaor hypothermia can suppress or even stop brain activity on a temporary basis.
Because of this, hospitals have protocols for determining brain death involving EEGs at widely separated intervals under defined conditions. Legal death The death of a person has legal consequences that may vary between different jurisdictions.
