It is when you inject, once the needle is in the muscle, you pull back on the plunger. If there's an air bubble, then your good to go on the injection.

Just to add to that.......if you get blood filling the syringe, then obviously you are in a vein and do not want to inject there. Also, when you pull back on the plunger, it is just a slight pull, if you pull to hard, you run the chance of collapsing a vein and not getting any blood in the syringe.

EXACTLY!!!! However....you only need to aspirate (pull back on the lunger) very slightly to see just a small air bubble. Also, do it very slowly, and STEADY to avoid moving the dart in the site...this will minimize soreness.
