Well, the final statement is actually true. If you consider the Ideal Gas Law (PV=nRT) and assume constant pressure and volume, a change of temperature will shift the value of "n" higher and thus raise the density of all the constituent gases. So yes, the oxygen would be more concentrated but so would the nitrogen and CO2. Doing the math though, under typical circumstances I think you'd be rather lucky to increase the gas concentration by more than 8%. So is it worth your time in case of an emergency? I dunno, couldn't hurt I guess.
