Pressure decreases as altitude increases.

Explanation:

This is true for any gas in equilibrium and not just limited to oxygen. Air at a lower altitude is compressed more due to the weight of a longer column of air above it. Therefore, the pressure will be higher.

This is evident in the fact that air gets thinner at higher places
