create a vacuum in your syringe. The oil cannot expand to fill that space,
but any air bubbles in your syringe will. You may notice the tiny bubbles
getting bigger and bigger as you pull back. They will return to normal
size as you release the plunger. If the air bubbles do not disappear upon
releasing the plunger, you have an air leak most likely caused by the
needle not being screwed onto the syringe tightly enough, although on very

and coughing fits when they inject into a blood vessel. But you need to be
aware of the dangers of neglecting this simple technique that should take
about 3-5 seconds of your time.
