How do partial pressures of gases influence one another?

Usually not at all.

Explanation:

#"Dalton's law of partial pressures"# states that in a gaseous mixture, the pressure exerted by a component gas is the same as the pressure it would exert if it #"ALONE"# occupied the container. In other words, given the same container, pressures are additive, and a partial pressure of a component gas does not influence the partial pressure of another component.

Of course the component gases could react with each other, but that's another story.
