I saw air get into my bloodstream once and got a terrible panic attack instantly(first one ever). My blood pressure rised and I started feeling like I could not breath. Air bubbles do not belong in the bloodstream. Air could get trapped in the brain or somewhere else.
Ohhhh, and having tingly hands during a panic attack is perfectly normal...it is your body pulling the blood from your extremeities because it thinks it is in danger, a perceived danger, even if your not actually in danger. It is a protective mechanism...it happens to me all the time. The best thing to counteract it is take long, deep, slow breaths for several minutes.
I use to freak out about this as well but at the hospital I was assured it would pratically take a whole IV line full of air to do anything bad to you. That movie The Omen, shows Julia Stiles die from a small amount of air in her IV tube, but that is just a load of bull, it that amount is completely harmless!
NOTHING to worry about.
Your arm, chest, shortness of breath and hands tingling are anxiety.
