I'm just curious.
I use oxygen on a regular basis for cluster headaches. I use a non-rebreath mask with my regulator set at 20-30 liters per minute (total trauma levels...). I fall asleep with it on all the time. Why don't I wake up dead?
In a human, without co2 in our bloodstream, it cannot possibly exchange oxygen. ur body does take some in from the atomosphere
ALSO most doctor prescribed oxygen tanks have about 5 % carbon dioxide in it. up to 15% for people who have trouble sleeping. this is to help regulate the bloodstream and your metabolism
for aquatic creatures. to much oxygen does what peroxide can do to gills.
oxidize them, rendering them useless and the fish unable to respirate
this is only possible through a pressurized injection source.. PLANTS or airstones CANNOT DO THIS
