The concept and causes of clinical and biological death. The difference, signs.

People live as if the hour of their death will never come. Meanwhile, everything on planet Earth is subject to destruction. Everything that is born will die after a certain period of time.
In medical terminology and practice, there is a gradation of the stages of body dying:
- sredagonia
- agony
- clinical death
- biological death
Let's talk more about the last two states, their signs and distinctive features.
The concept of clinical and biological death: definition, signs, causes
Clinical death is a borderline state between life and a biological death, lasting 3-6 minutes. Its main features are the lack of heart and lung activity. In other words, there is no pulse, breathing process, signs of body life.
- Medical terms are signs of clinical deaths are a coma, asystole and apnea.
- The reasons that caused her offensive are different. The most common - electric trauma, drowning, reflex cardiac arrest, abundant bleeding, acute poisoning.
Biological death is an irreversible state when all the life processes of the body have ceased, brain cells die. Its signs in the first hour are similar to clinical death. However, then they acquire a brighter severity:
- herring gloss and veil on the rainbow shell of the eye
- cadet purple spots on the lying part of the body
- dynamics of temperature reduction - every hour by a degree
- harding muscles in the direction from top to bottom
The causes of biological death are very different - age, cardiac arrest, clinical death without attempts to resuscitation or later their use, injuries incompatible with life obtained in accidents, poisoning, drowning, and falling from a height.
How clinical death differs from biological: comparison, difference
- The most important difference between clinical death and biological is reversibility. That is, a person can be returned to life from the first state, if you resort to resuscitation methods in a timely manner.
- Signs. With clinical death, cadaveric spots do not appear on the body, its winding, narrowing of the pupils to the “cats”, and clouding of the rainbow shells.
- Clinical is the death of the heart, and biological - brain.
- Fabrics and cells continue to live without oxygen access for some time.
How to distinguish clinical death from biological?
A person far from medicine, at first glance, determine the stage of dying is not always simple. For example, stains on the body, similar to cadaveric, can form in the observed during life. The reason is a violation of blood circulation, vascular diseases.
On the other hand, the lack of pulse and breathing is inherent in both types. Partly will help distinguish between clinical death from the biological state of the pupils. If, when pressed, they turn into a narrow gap according to the type of cat's eyes, then there is biological death.
So, we examined the differences between clinical and biological death, their signs and causes. Established the main difference and vivid manifestations of both types of dying of the human body.
