what would happen if you permanently oxidized blood?

[Legolessed]

I know people in athletics have injected oxygen rich blood into their system for a boost in performance but what would happen if you were able to permanently keep the blood oxidized? What if you were able to artificially take blood from your veins, reoxygenate it and pump it back into the body, like the lungs do, but instead of doing it at just one place in the body, what if you reoxyginated the blood in multiple places, allowing the blood to be permanently oxygenated? would said human had little physical limitations when it came to cardio? also what if you were able to inject something in you, that would have a chemical reaction once in your bloodstream that would oxyginate your blood. Like sodium chloride but with something that reacts to blood?

Death by oxygen poisoning. That's what will happen.

A normal human might experience some extended physical endurance temporarily. Then they'd probably die.

 

You'd have to genetically modify the person so that their body can actually sustain the greater oxygen content in their blood on an ongoing basis.

 

But that person would also be extremely susceptible to low oxygen environments like High Altitude or smoke from a fire, etc, as their body would come to rely on the greater oxygen content.
