Clinical+Death

=Definition:= A period during which vital signs are absent but resuscitation is still possible. HGD Chapter 19, p. 484

**Another definition:** __**Clinical** **death**__ is the medical term for cessation of blood circulation and breathing, the two necessary criteria to sustain life.It occurs when the heart stops beating in a regular rhythm, a condition called cardiac arrest. [|http://www.princeton.edu/~achaney/tmve/wiki100k/docs/Clinical_death.html]

Stopped blood circulation has historically proven irreversible in most cases. Prior to the invention of cardiopulmonary resuscitation (CPR), defibrillation, epinephrine injection, and other treatments in the 20th century, the absence of blood circulation (and vital functions related to blood circulation) was historically considered to be the official definition of death. With the advent of these strategies, cardiac arrest came to be called "clinical death" rather than simply "death" to reflect the possibility of post-arrest resuscitation; for medical purposes, it is considered to be the final physical state before permanent death. At the onset of clinical death, consciousness is lost within several seconds. Measurable brain activity stops within 20 to 40 seconds. Irregular gasping may occur during this early time period, and is sometimes mistaken by rescuers as a sign that CPR is not necessary. During clinical death, all tissues and organs in the body steadily accumulate a type of injury called ischmic injury.

No breathing, no circulation, and no brain activity characterize clinical death. But that's only half. The other side, the most integral part which separates clinical death from somatic death, is that clinical death begins at the very onset of the symptoms of death, say right after cardiac arrest has cause the heart to stop. It lasts for about four minutes, and it is the interval in which life can be brought back through CPR. After a short few minutes, death is permanent, because the state of the body has gone from clinical death to... Otherwise to summarize this paragraph above clinical death is the type of passing in which the body stars to die and can lead to death.

= Examples: = 1. Cardiac Arrest patients are an example of clinical death, and sometimes they are brought back to life. People who report near-death experiences are presumably in a state of clinical death.





= Analogies: = There is an old saying that, "you are not dead until you are warm and dead."

Make sure they are dead before you start sobbing on their head.
