Just pull back .15 of air and that will be enough to get it all out. Just let one drop come out the needle and flick the remaining air bubbles out before you inject
Recently been in hospital (unrelated to forum topics). The hospitals can/do use alot of air in injections. Although they advised me that there needs to be alot of air in the injections to be a problem, i had them be vigilant with the air.
It really depends on how you go about thinking about it. I personally think if there's an issue at some form of an amount. I'd rather not have it at all, particularly if you cant stop it until it's too late.
Where does your body draw the line? I'd rather not find out.
I could only imagine you body making some form of clot from it, no matter how small it may be. - The experts say it's fine, so believe what you would rather.
Also bear in mind we’re all injecting into muscle and not veins so our risk is even lower again as the air disperses in the muscle for slow absorption.
