All death caused by lack of oxygen to brain

Click For Summary
SUMMARY

All deaths are fundamentally caused by a lack of oxygen to the brain, as established in the discussion. However, the clinical definition of death includes the absence of neurological activity, which can occur even if oxygen is present. The debate highlights that while oxygen is essential for brain function, other factors, such as trauma or neurological failure, can lead to death despite oxygenation. Thus, the assertion that all deaths are solely due to lack of oxygen is overly simplistic and does not account for complexities like brain death and organ viability.

PREREQUISITES
  • Understanding of clinical definitions of death
  • Knowledge of brain physiology and oxygen requirements
  • Familiarity with neurological activity and brain death criteria
  • Basic concepts of organ viability and artificial life support
NEXT STEPS
  • Research the clinical criteria for brain death and its implications
  • Study the effects of oxygen deprivation on brain function
  • Explore the physiological limits of oxygen consumption in humans
  • Investigate the role of artificial life support in organ viability
USEFUL FOR

This discussion is beneficial for medical professionals, neurologists, and anyone interested in the complexities of death, brain function, and the ethical considerations surrounding life support systems.

I saw this in a locked topic:

All deaths (100%) have the same cause: lack of oxygen to the brain.

even if you strap yourself with 500 kilos of dynamite and blow it up? and what if you actually pump oxygen into your brain, and die because of that?

Who is right?

Technically, if one could isolate the brain and provide it with oxygen and nourishment (e.g. glucuse), one would be considered 'alive'.

One has to look at the clinical definition of death. Clearly, without oxygen, the brain dies.

On the other hand, if there is no neurological activity, then one is considered 'brain dead', but the other organs could be kept alive 'artificially' for some time. One could oxygenate the brain, but if the brain cells have ceaesed to function, and are decaying, then the brain is dead, and one is dead.
 
i think that it is not 100% deaths because of lack of oxygen to the head, i mean just like he said strap yourself with 500 kilos of dynamite and your still breathing the second it goes off you die because your brain got blown into bits not because oxygen didnt get to your brain, plus he is again right, humans cannot breath in pure oxygen because then they die, that just disproves his theory
 
Well, I suppose if you try really hard you can find ways of disassembling the brain such that it stops living even though there's no lack of oxygen...

but really, isn't that stretching it a bit?
 
And that's why some threads have been locked, and should stay that way. :rolleyes:
