I'm sorry man, but this doesn't make any sense.

This situation should never arise because it's easy to remove all air from a syringe before you IV.
But if you do find yourself with an air bubble in the barrel and you can't be arsed to get rid of it, then just ensure the plunger is higher than the needle because the bubble will rise up to the plunger end ensuring that the business end is all primed and ready to go. If you have the needle higher than the plunger, then the bubble will rise to the needle end leaving a gap between your gear solution and the needle. This means that registering won't be as obvious when you draw back because you won't see the little cloud of blood filling the barrel.
However, having air in your barrel is undesirable because as you suspect, it will affect the suction. Air is easily expanded and compressed. This means that drawing back and injecting will involve greater movement of the plunger to achieve the desired effect because the air is acting like a cushion.
This is why you should ensure that the barrel is air free before going any further. When there is no air in the barrel, the slightest movement of the plunger is transferred directly to the needle end, giving you much finer control.
Finally, don't worry about injecting small air bubbles, you won't drop dead. It takes several CCs of air to do any damage.
