Blood sample.?

A sufficient quantity of air injected directly into an artery or vein has the potential to cause an "air embolus" which could indeed be fatal. We do run whatever is going through an IV through all the tubing (saline or Ringer's solution or whatever) to drive out the air before we start an IV, but you often do see a small bubble of air running through a line and it's not a cause for concern. You have to get a fairly major amount of air all at once to cause an embolus (like a whole syringeful). It would be a serious error.

An ordinary injection into the arm or leg or buttock is going into muscle or fatty tissue or just under the skin and air in the syringe would not be dangerous at all. The only problem there, and the reason that you see doctors and nurses pushing the syringe until all the air is out, is that if there is air in the syringe then there is NOT medication in that area, and you will not be giving the exact amount you mean to.

A small amount of air is not a concern. Some components of air are always dissolved in the plasma itself. That is what eventually would happen to the air in the bubble.

It would have to be a LOT of air. I forgot the amount but a lot more than just a small air bubble!

when drawing blood you are pulling not pushing the blood. even if a small air bubble were to enter it wouldn't cause a problem. the body would just compensate.

air embolism tha leads to, is a fatal medical emergency.

Thatswhy, one person should always be present near the pt when drip medication is administered.

He / she should call themedical attendant when the fluid level reaches close to the tip of the the drip needle inserted

If the med attendant doesnt come the regulator shouldbe operated to stop the drip

Don't you think a phlebotomist ( the guy who draws blood) would be the person to ask? If not, how about a nurse or doctor?

u will die due to air lock its definite no one can save u

good bye
