as a nurse i can tell you that it actually takes about a litre of air in your blood stream before any damage starts occuring, the reason why we tap the syringe to get the bubbles out is so that we have an accurate measure of what we are giving, it is not to stop an air bubble getting into the blood stream as like i said above, unless you pump about a litre in, nothing adverse will happen.
