How Long Can A Brain Last Without Oxygen
My niece was without oxygen for about 5 minutes was brought back but is now comatose for 13 days now she has brain damage and had EEG had 7 seizures?
Hypoxic encephal.: The hypoxia has likely resulted a secondary brain injury, and depending on age, the extent of recovery will be unknown for some time. The seizures are not unexpected and will need control, but likely not to be a long-term challenge. Have a neurology consult, provide supportive care, and hope for the best. ...Read more

So sorry: Sorry to hear of this devastation. Cant tell exactly what's being asked, but will take a shot:there are many variables that go into how long a body can continue to function post cardiac arrest. The respiratory center is buried deep in midbrain, protected by the cerebral cortex. It can continue to function and effect respirations even after severe oxygen deprivation. I've seen go for several days. ...Read more
Does oxygen desaturation on a long-haul flight (13.5 hours) cause any sort of brain damage to a baby? I've read they go as low as 80% and lower.
Odd comment: Babies with a normal lung structure will maintain normal oxygen levels on a long flight the same way any adult or older child would. There is no drop in the blood oxygen level during a flight. Pressurized air craft are a safe mode of travel for infants. Someone is providing you with goofy information. ...Read more
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. ...Read more

Brain injury: If the brain does not get enough oxygen, a lot of problems can occur, such as dizziness, memory loss, seizures, and unconsciousness. If the brain is deprived of oxygen for a prolonged period of time, permanent damage can occur and is called anoxic (or hypoxic) brain injury. Someone with this condition is usually very sick and may be in a coma. ...Read more

No.: It may alter your sensation for a few seconds, but I would not say it makes you high. Kills a few brain cells along the way and depending upon the technique you use could result in permanent damage and death. ...Read more
All nutrients.: Your brain cells need whatever your other cells in your body need, only more often. One nutrient needed most is glucose, which is vital to correct brain function. That's why hypoglycemia is so very dangerous to the brain, as a drop in glucose can mean death of brain cells. Oxygen is also very important, and a lack of oxygen to the brain can cause massive brain cell death or a stroke. ...Read more

Why do people yawn? I heard yawning is a sign that your brain isn't getting enough oxygen. Is this true?
True: Yawning is a sign of tiredness. Additionally, when your carbon dioxide (the gas given off with exhaling) level starts to rise in your body, it does stimulate the brain to cause you to yawn. The theory is that the yawning will cause you to take a deep breath and inhale more oxygen and exhale the excess carbon dioxide. ...Read more
I don't breathe shallow or rapidly. And don't gasp for air...But I have white-outs and feel like brain/body isn't getting oxygen. What can cause this?
Tough to say: Without examining you fully and getting tests done, it is tough to say. You need to see a dr. For an eval as several issues including many metabolic issues (example: high or low blood sugar), neurological (example: seizure d/o), cardiac (example: arrhythmias, etc), are all possible...Best to get an eval. Good luck! ...Read more
