I wonder how you got this idea. If you want to increase your output nothing works better than starting the day with a 30 minute walk. Every 2 hours do some exercise for 5 to 7 minutes. This is also cheaper. I recommend doing a few squads as it is the best exercise.

I got the idea from noticing that the CO2 level can make it harder for me to think, so I wondered what would happen if I went in the other direction (more oxygen).

Buy a $20 SpO2 monitor, and realize that your blood is already saturated with O2. You'll find that you're generally between 97%-99% to begin with, so what is adding oxygen going to do? The amount of oxygen that reaches your tissues is a function of the carrying capacity of your erythrocytes, and unless you're very sick or in an extreme environment, that isn't driven by ambient O2 levels.

how are measuring this “harder to think” feeling to avoid confirmation bias?

yeah that's a great point, I need to come up with some way to measure it.
