Did I oxidize when I kegged?

This weekend I transferred an ESB to keg. I was having some trouble with my auto siphon that led to a lot of bubbles in the line. I tried to correct it but ultimately ended up stopping the flow and trying to restart my siphon. While fidgeting with cursed tool I failed to notice that while pumping I was above the wort for a bit and was blowing bubbles in my keg. After I finished transfer I purged it with CO2 several times hoping to remove as much oxygen as possible. Did I ruin my beer?

You probably didn't ruin it. In my experience you have to get pretty violent to get enough oxygen in your brew to really mess it up. Just don't dump the beer into the keg from the carboy/bucket.
