I did not mean to emply for anyone to try this, I just was concerned about what I was told to do, I will never do this again and I do not recommend anyone doing that. I wanted to know if I could have caused any harm. It was for my peace of mind.

I was participating in an extern program and following a nurse around. She asked me to start an IV and then withdraw blood from the IV site (specimen). While doing so I pushed up a little on the syringe after asking if I could do so, I thought that my help with retrieving the blood, and the nurse stated that I could. This was an IV in the hand. I then started worrying about air emboli/pulmonary emboli so I started doing some research on air emboli/pulmonary emboli and found an article that stated that small amounts of air do not produce symptoms because the air is broken up and absorbed from the circulation. Although classical teaching states that more than 5 mL/kg of air (IV) is required for significant injury (including shock and cardiac arrest), patient complications secondary to as little as 20 mL of air (the length of an unprimed IV infusion set) have been reported. Further, as little as 0.5 mL of air in the left anterior descending coronary artery has been shown to lead to ventricular fibrillation. My question is this .5ml of air they are talking about could this occur from an IV in the hand or is this with central IVs?
