Not good...: If you "black out" from lack of oxygen, it means your brain in not getting enough oxygen. It could also mean integer organs are not getting enough oxygen, like your heart, kidneys, liver, etc. You need to find out why you don't have enough oxygen and get treatment, which may include supplemental oxygen, if needed.
