Since gear isnt administered IV there would be no reason that i know of that this could hurt you. If you didnt aspirate and injected into vein then..well then you prolly would have several issues as well as o2 in your bloodstream. Even o2 in the bloodstream is overated as to its dangers..unless you get o2 injected into an artery..here are a few quotes from Wikpedia regarding air embolism.

The danger of air bubbles in your circulatory system is from the air itself displacing blood. O2 has nothing to do with it.
