What is the minimum number of nanocontainers that a person would need in their bloodstream to provide 1 hour's worth of oxygen?

I did some research and found that the average human requires 550 L of oxygen per day which means that:

(550 L O2 / day) x (1 day / 24 hours) = 22.9166667 L O2 / hour or 22916.67 mL O2 / hour

1 mL = 1 cm^3

22916.67 mL O2 / hour = 22916.67 cm^3 O2 / hour

Now convert that volume from cm^3 to nm^3

22916.67 cm^3 O2 / hour = 2.29167x10^25 nm^3 O2 / hour

So for 1 hour’s worth of O2, we need a volume of 2.29167x10^25 nm^3
