Bubbles in the syringe

My goal is no bubbles and this is why. This is talking about what happens when air enters a vein during intravenous treatment.

"Air bubbles of less than 30 milliliters are thought to dissolve into the circulation harmlessly. Small volumes do not result in readily detectable symptoms, but ongoing studies hypothesize that these "micro-bubbles" may have some adverse effects. A larger amount of air, if delivered all at once, can cause life-threatening damage to pulmonary circulation, or, if extremely large (3-8 milliliters per kilogram of body weight), can stop the heart.

One reason veins are preferred over arteries for intravascular administration is because the flow will pass through the lungs before passing through the body. Air bubbles can leave the blood through the lungs. A patient with a heart defect causing a right-to-left shunt is vulnerable to embolism from smaller amounts of air. Fatality by air embolism is vanishingly rare, in part because it is also difficult to diagnose."

Well seeing as i have never injected IV, im not worried about that at all. I have around 100 injections with an air bubble and never once has it affected me. If your in a vein you should know before you get anywhere near the air bubble

Ok I see your logic. You first make sure you aren't in a vein by aspirating and then you are gtg. Apologize if I came across as ambushing with my copy paste job.

Its fine. I understand why you would worry. But yeah, i aspirate with the needle facing down in the muscle so the bubbles is in the top . If i am in a vein i have neither injected oil nor air so it wouldnt matter. Just pull it out replace needle and move over a little, inject again, aspirate, if no blood inject.

The air will help to push the oil that remains in the top of the needle. Once in the muscle it will just dissolve and you will never know the difference
