Question 1

what are we doing in brain damage by lack of oxygen?

Accepted Answer

Hypoxia/anoxia: A lack or deficit of oxygen to the brain can occur for a variety of reasons. The term for this is hypoxia. Complete lack of oxygen is referred to as anoxia and is more severe. The neurons are particularly sensitive to this lack of oxygen and will die. This then results in the brain damage. In the most severe cirucumstances, this can lead to death of the patient.

Question 2

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.

Question 3

how long does it take before brain damage occur from lack of oxygen to the brain?

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. If the body had been cooled by submersion in cold water it could be much longer. Less severe lack of oxygen will take longer to produce brain damage.

Question 4

when you pass out from lack of oxygen is the oxygen at that point low enough to cause brain damage?

Accepted Answer

Hypoxia: Yes it is low enough to cause brain damage.

Question 5

can you get brain damage from lack of oxygen from snoring?

Accepted Answer

2 different events: Snoring results from vibration emitted from the upper airways, for instance a sides of the nostrils moving toward the septum during inhalation or more likely from vibration of the soft palate, uvula &  perhaps tongue. Snoring is a noise. Its cause is airway obstruction. Severe obstruction blocks oxygen getting into the lung, hence possible brain injury--consider having polysomnogram test.

Question 6

i just found out im covid positive at 38 weeks. i have sever outburst of shortness of breath and coughing. can that cause fetal hypoxemia? im terrified this has caused brain damage in baby from moments of lack of oxygen?

Accepted Answer

: I would not fret about this. The fetus will get enough as long as you are not in a coma from lack of oxygen. Worry about your own health for now &amp; make plans for how you deal with a newborn.

Question 7

70% brain damage, not in a single area, due to lack of oxygen (caused by asphyxia), what are the chances to awaken and regain full consciousness?

Accepted Answer

Unlikely: The extent of brain damage is not as important as the specific areas of the brain that are affected. So, if the pons or medulla were affected, you would be considered brain dead already. But, if you loose that much area, you will have significant mental status changes and impairments of motor function. This is not a good circumstance.

Question 8

can smoking cigarettes cause brain damage due to lack of oxygen or something?

Accepted Answer

Indirectly: Smoking is a major cause of arteriosclerosis, narrowing of arteries  and reducing blood flow to the brain as well as strokes. All can lead to brain damage.

Question 9

im 7 months pregnant and every now and then ive been sleeping with my head under the covers. i just read an article about lack of oxygen and now im concerned about my baby. could i have caused brain damage to my baby?

Accepted Answer

: If you breathing is normal, there is unlikely to be any harm.  Have regular visits with your OB specialist.

Question 10

ive had a habit of sleeping with my head under the covers for majority of my pregnancy. i just read that its not good for the baby due to lack of oxygen so now im worried i may have caused brain damage to my unborn child?

Accepted Answer

: I consider the statement a myth. Your own body needs oxygen and when/if you did not get the normal amount while sleeping in any position the fail-safe systems your body uses to keep you going will force you awake. Discuss this with your OBGYN. The pattern your baby grows that is verified during your check-ups shows baby will do fine.
