A member asked:
Hi, i have a question about cerebral hypoxia brain damage. if i were to empty my lungs of all air and hold it for 30 seconds while taking 4 very small, fast hyperventilation like breathes, would that give me brain damage? can you explain?
A doctor has provided 1 answer
No.: Breath holding may result in loss of consciousness but breathing is under automatic control. You would start breathing again immediately. The degree of hypoxia during breath-holding is not sufficient to cause brain damage. Thanks for trusting HealthTap!
