Question 2

is it possible for someone to pass out due to lack of oxygen and seize and while passed out remain completely aware that they are seizing? also, can someone pass out due to lack of oxygen and wake up just fine without any medical intervention?

Accepted Answer

: Interesting questions: First, a seizure represents an alteration of consciousness, and a generalized event secondary to hypoxia would not preserve awareness.  Second, lack of oxygen can result in syncope, and if re-oxygenation occurs in under 3 minutes, would not expect permanent damage.

Accepted Answer

4 minutes or more: In the event of a full blown cardiac arrest there can be brain damage in as little as 4 to 5 minutes without circulation at normal body temperature.

Question 8

how harmful for your health is it for you to black out from lack of oxygen?

Accepted Answer

Not good...: If you "black out" from lack of oxygen, it means your brain in not getting enough oxygen. It could also mean integer organs are not getting enough oxygen, like your heart, kidneys, liver, etc. You need to find out why you don't have enough oxygen and get treatment, which may include supplemental oxygen, if needed.

Question 9

will you die faster from lack of oxygen to the brain or glucose or other nutrients not getting to the brain?

Accepted Answer

Anoxic Brain Injury: Both glucose and oxygen are needed for brain metabolism and the brain cannot tolerate being without oxygen more than 5 minutes.

Question 10

can you get brain damage from lack of oxygen fainting?

Accepted Answer

Yes: The human brain can withstand at most 4 minutes of oxygen deprivation before experiencing brain damage. Damage may be irreversible at this time but the brainstem is more resistant, hence the occurrence of "persistent vegetative state". But a simple faint can result from only a few seconds of oxygen deprivation without causing long-term damage.
