Not everyone will show symptoms from having air bubbles in the blood vessels but it can be a life-threatening condition. Bubbles formed in the vein through deliberate air injection can be pretty huge and may block the blood vessels. When this happens it is called embolism. The bubbles can travel all over your body and get stuck in any blood vessel anywhere. But since you inject the bubbles into a vein, it will travel back to the heart and further to that possibly the brain. If it gets stuck anywhere in those two critical places, it can be fatal. One of the most effective treatment for air embolism
is the administration of supplemental oxygen
. The administration of 100% oxygen can decrease the size of the air embolus (bubble causing the blockage) by causing nitrogen to diffuse out of the air bubbles and into the alveoli, a phenomenon referred to as nitrogen washout.
