Nitrous Oxide/Oxygen Deprivation Brain Damage?
Over a short period of time I inhaled 140 balloons full of pure nitrous oxide. Each time I would exhale until my breath was gone, suck the contents into my lungs, breath it back into the balloon and repeat about four times. Each time my vision would black out but I would still be conscious but on the verge of passing out. I read that vision blackouts are a symptom of severe hypoxia and nitrous oxide exacerbates this by displacing oxygen in the blood and lungs.
What are the chances I did damage to my brain, heart and body?
